Glenn Rhee (TV Series)

"Those four people you lost on that run, that's on you. And Noah, that's on you, too. Those five lives, you have to carry that. People like you are supposed to be dead, but these walls went up just in time, so you're not. You don't go outside those walls anymore. Not by yourself, not with anyone else. And that's how you're gonna survive. (...) I'm someone who knows who you are. I know what you did. And it's not gonna happen again. (...) Don't forget what I said. (...) No. I'm saving you."

- Glenn to Nicholas

Glenn Rhee is a main character and survivor of the outbreak in AMC's The Walking Dead. He is the main supply runner for the Atlanta camp group and saves Rick Grimes in the walker-infested Atlanta, bringing him back to his camp to reunite him with his family. Eventually, after the group stays on the Greene farm, Glenn forms a long lasting relationship with Hershel Greene's daughter, Maggie, and marries her. At the West Georgia Correctional Facility, which his group establishes as its base, he becomes a reliable council member but falls ill to a sickness that prevents him from doing his duty. After the prison assault that leaves it destroyed and many dead, Glenn escapes and reunites with his wife, while following Abraham Ford on a journey to Washington, D.C.. He is among the new recruits to go to the Alexandria Safe-Zone, where he becomes a supply runner.

Personality
Glenn is bright, loyal, resourceful, fast, quick-thinking, and brave. Keenly aware of the extreme dangers he puts himself in for the group, his youth makes him willing to take the risk. Glenn thinks on his feet and shows great compassion and humanity. Despite all the horrors he has seen, he maintains a youthful enthusiasm for life and its unexpected pleasures. He is an integral part of the group, showing surprising depth and emotion when experiencing even the most devastating tragedies.

While on the farm, he begins a relationship with Maggie Greene. Over the course of the latter half of season two and the third season, he has become extremely close and loving toward her, doing whatever is necessary to keep her safe. He is trustworthy and loyal, as seen in the episode "When the Dead Come Knocking", when Glenn and Maggie are captured by the Governor, he is brutally interrogated by Merle but will not reveal where the rest of Rick's group have set up camp.

Glenn's love for Maggie and his close bond with her father, Hershel Greene, leads Glenn to become less of the group canary in the coal mine and more of his own voice. Upon Hershel's death, Glenn pledges to take over his role as conscience and hope, which involves decisions like protecting Tara Chambler in spite of her ties to the Governor, and encouraging his leader Rick Grimes to spare the residents of Terminus. However, after discovering that Eugene Porter was lying about Washington and finding out Maggie's sister Beth was alive and later seeing her dead on the same day, Glenn noticeably becomes much colder and less trusting. This is shown when he says that he would have killed Dawn Lerner, who accidentally killed Beth, himself and that he would not have stopped to help the man trapped in the storage container at Terminus, whom he had convinced Rick to rescue.

Atlanta, Georgia
Glenn was originally from Michigan, born of Korean immigrants. He moved to Atlanta sometime within his adult years, where he delivered pizzas for a living. As it turned out, his knowledge of every short cut in Atlanta proves extremely useful to the group's scavenging needs. In the episode "Cherokee Rose", Glenn wears a shirt that has some Boy Scout markings on it, a sign indicating that he may have been a Boy Scout.

He knows the city fairly well and can navigate his way through back alleys and the streets. When the outbreak began and the city was converted into a refugee center, Glenn, being resourceful, was able to survive despite the city quickly being overrun by walkers. He mentions having been saved by Theodore "T-Dog" Douglas before linking up with the rest of the Atlanta camp survivors.

In the episode "Nebraska", Glenn talks about his mother and reveals that he has multiple sisters, but their fate after the apocalypse is currently unknown.

"Days Gone Bye"
At the end of the episode, when the horse Rick Grimes is riding on into Atlanta is attacked and eaten by walkers, Rick is able to escape and climbs into a tank to hide from the swarm of walkers outside. Glenn contacts Rick via radio after Rick shoots a walker inside it and says, "Hey you... Dumbass... Yeah, you in the tank... Cozy in there?"

"Guts"
Rather than go into Atlanta alone, Glenn brought more people with him to scavenge for supplies (though he later comes to regret the idea since this was the first time he did it. And the results were not as favorable as working alone). He spots Rick as he was attacked by a mob of zombies upon entering the city and sees him escape into a tank parked in the middle of the street. Glenn manages to reach him through the CB in the tank and helps him escape the zombie mob. He then later leads Rick to his group as they try to think of what to do next since the zombies are aware of their presence (due to Rick's earlier action, though he was unaware there were survivors). At first the group thinks they can escape through the sewer, but Glenn scouting it with Morales reveal bars blocking their way and a zombie feasting on a rat. After telling the others that idea is out, Rick gets the idea to put zombie entrails on their person to mask their scent and wade through the zombies to get transportation. Glenn volunteers to go with him and the two make their way to a parking lot. The plan works until a sudden rainstorm passes through and washes off the entrails, giving the two away. Rick and Glenn are forced to run but manage to make it to the lot and secure a loading truck. Realizing they need a distraction, Rick hot-wires a Dodge Challenger and has Glenn lead the zombies away from the store while Rick picks up the others. The plan succeeds and Glenn is seen leaving Atlanta in the Challenger, whooping in victory. He makes a great asset to Rick's group.

"Tell It to the Frogs"
After they all get back to the camp-site and reunite with the other survivors, Glenn is asked by Rick to go with him back in the city because he knows his way in and out. He leads Rick, T-Dog, and Daryl Dixon to the building that Daryl's brother Merle was handcuffed onto. Heading up the stairs they find no walkers. On the roof, Daryl calls out to Merle, but they only find Merle's hand, a bloody hacksaw, and the bloody handcuffs.

"Vatos"
When Rick decides to go back for Merle he enlists the help of Glenn because of his knowledge of the city. Glenn reluctantly agrees and joins the party to go save Merle. In the city, they realize that Merle was able to escape by cutting off his hand and after following Merle's bloody trail the group starts to organize how to get the bag of guns back. Glenn organizes the plan to get the guns like a skilled tactician arguing that he's agile enough to get in and out of the streets. At one point Daryl asks Glenn what his profession was before the apocalypse to which Glenn replies, "Delivered pizzas. Why?" Glenn succeeds in acquiring the weapons, but is taken hostage by a group called the Vatos who also want the guns. Rick and the group come to the Vatos hideout with a hostage called Miguel but the negotiation goes badly and both groups draw their guns on each other. The battle is interrupted by Abuela, a woman who reveals to the group that the Vatos are actually looking after an abandoned nursing home and its residents. The group decide to split the guns between themselves and the Vatos group, and return to the spot where they left the van only to find it missing. Assuming Merle to be the culprit, they immediately head back to camp and are just in time to fend off an attacking herd of walkers.

"Wildfire"
After the attack on the camp-site which left many people dead, he and the others struggled to decide what to do with Jim, who was bitten. Glenn says his goodbyes to him, as does everyone else, and leaves the man sitting by a tree.

"TS-19"
Following their arrival at the CDC, Glenn takes advantage of the building's luxuries (food, clean clothes, etc.), and follows around the rest of the survivors. He, along with everyone else except for Jacqui and Dr. Edwin Jenner, escape the building before it explodes, and then head to Fort Benning, a military base.

"What Lies Ahead"
Glenn was forced to stop along with the others when Dale Horvath's RV breaks down. He is then later seen fixing an old truck; when a herd of zombies come their way, he hides under a car with Shane Walsh. Sophia Peletier then gets chased by a duo of zombies and the group looks for, but she is not found by the end of the episode.

"Bloodletting"
Glenn and the group continue to look for Sophia when all of a sudden Maggie Greene appears on a horse and takes Lori and tells Glenn and the others to head to their farm they make it back to the highway, but Sophia's mother Carol does not want to go and wants to keep looking for Sophia.

"Save the Last One"
Glenn makes it to the farm with T-Dog and watches Hershel perform surgery on Rick's son Carl. He then sits out on the porch, prays for this to end and starts to form a relationship with Maggie (Hershel's daughter). Glenn then waits for Shane and Otis to return to the farm with the supplies. Shane reveals that Otis is dead and Glenn feels sorry even though he didn't know him.

"Cherokee Rose"
At the farm, Dale and T-Dog find a walker inside of one of the wells, and the group quickly rallied to devise a plan to rescue the walker from the well without contaminating the water. The survivors then lower down Glenn as bait. The plan goes awry when the old rusty water pump they’re using as a pulley breaks, sending Glenn within reach of the ravenous reverent. They save Glenn who, despite his panic, managed to lasso the corpulent creature. Unfortunately, the risk and subsequent struggle to haul out the zombie is all for nothing, as its rancid body gets snagged on the lip of the well only to rip in half, dropping its fetid bowels into the water below.

Later, Glenn and Maggie go for an excursion to the local pharmacy to get more medical supplies and a pregnancy test for Rick's wife Lori, and while they are there, they end up having sex.

"Chupacabra"
Glenn is frustrated by Maggie's hot and cold behavior towards him. He shares a theory with Dale that all of the women are acting strangely because their menstrual cycles are aligning. Dale advises him to keep that theory to himself, and also discovers that Glenn and Maggie had sex. He mentions that Hershel would likely not approve, to which Glenn replies, "Tomorrow I might be dead." Glenn is the only person at this point that knows Lori is pregnant. Maggie passes a note to Glenn during dinner asking him where he thinks they should have their second sexual encounter, and he replies the (barn) loft. But Maggie does not read his reply right away. Glenn sets out to investigate the barn and wait for Maggie, but makes the shocking discovery that the barn is already in-use as a containment and concealment vessel for numerous walkers.

"Secrets"
Glenn, unable to hold the secret of the barn, tells Dale about it, as well as Lori's pregnancy. After this incident, Maggie feels betrayed by Glenn and initially refuses to speak with him, though she does another run into town with him. While there, Maggie is attacked by a walker and Glenn jumps in to rescue her. They manage to get Lori´s morning after pills, which Rick finds.

"Pretty Much Dead Already"
Glenn reveals to the whole group that there are walkers in the barn. Maggie is again frustrated by Glenn's inability to keep secrets, but he reassures her that it was to keep her safe. Later, when he participates in the shooting at the end of the episode with Shane, Andrea, T-Dog, and Daryl, he first looks at Maggie for approval of shooting, and she agrees.

"Nebraska"
At Hershel's home, Maggie asks Glenn if he would stay if the rest of his group were to leave, but Glenn is unsure how to answer. Beth suddenly grows ill and collapses. She suffers from a fever and other serious symptoms, and seems to be in some state of shock. The group looks for Hershel to care for Beth, but discover that he has vanished, leaving behind his empty flask as a clue. Rick decides to look for Hershel at the local bar, and takes Glenn as backup. En route to town, Glenn confides to Rick that Maggie told him she loved him. Rick says that they need more good things like that in their lives, and that he should embrace those moments. At the bar, Rick and Glenn find Hershel and tells him about Beth. Hershel reflects that he had robbed his daughters of a normal grieving process by giving them a false hope, and allowing himself to believe it too. Hershel also says that Rick must relate, saying he saw the same feeling wash over Rick's face when Sophia emerged from the barn that there is no hope. Rick argues that nothing has really changed, and people are counting on them to be strong. They are interrupted when the bar door opens and two strange men walk in, identifying themselves as Dave and Tony. The five men converse cordially at first, but the strangers become impatient when Rick's group will not divulge information about the Greene farm. Glenn and the group are immediately untrustworthy of the strangers when Tony loses his patience and says he is considering shooting them all. When Dave reaches for his gun, Glenn watches as Rick pulls out his gun and shoots the two men.

"Triggerfinger"
At town, after killing Dave and Tony, Rick, Hershel, and Glenn are about to leave but instead get pinned down in the saloon by members of Dave and Tony's group: Sean, Nate, and Randall. Rick tells them that Dave and Tony pulled their guns out on them first but the group begin to shoot. Rick tells Glenn to check the back exit. As Glenn walks down some creaky steps and approaches the door, a shadow outside reaches for the handle and begins to twist it but Glenn shoots through the glass and scares him off. Rick tells Hershel to cover Glenn while he makes a run for the car. A man named Sean who was part of the group sneaks up behind Glenn and attempts to shoot him but Hershel shoots and wounds Sean, who starts crying out in pain. Rick asks Hershel what happened, he says he thinks Glenn was hit. Rick finds Glenn is just frozen behind a dumpster and approaches him. Rick, Hershel, and Glenn return to the farm with Randall blind folded in the backseat as a hostage. The group argues on what to do with Randall, Rick says they will fix him up and than drop him off to defend himself but Shane thinks that he will tell his group where the farm is and this will start a war. Hershel reminds Shane that it is his farm and while he is there he needs to keep his mouth shut. Maggie pulls Glenn aside and asks him if anything is wrong, he explains how her father saved his life, and that he froze and could not do anything to help. He had froze because she told him that he loved him, and he was afraid to die because of how it would affect her. She tries to embrace him, but he pushes her away.

"Judge, Jury, Executioner"
In the farmhouse, Glenn finds Hershel checking up on Beth. Hershel asks Glenn about his family and tells him about his own Irish heritage. He hands Glenn a pocket watch that belonged to his grandfather. "No man is good enough for your little girl," Hershel says, "until one is". As the sun sets, Rick again asks Lori if she thinks he's doing the right thing. Lori nods. The group gathers in the house. Rick asks if anyone thinks Randall should be spared. Dale posits that the only people who think so are himself and Glenn, but Glenn too sides with Rick. "He's not one of us," Glenn offers. Glenn along with all the other survivors gather around Dale before he is shot by Daryl to prevent reanimation.

"Better Angels"
Glenn attends Dale's funeral and is sad because he regrets going against the latter's wishes to spare Randall, but Andrea comforts him and tells him that Dale was proud of him overall and knew how much Glenn cared for him. Later, Randall disappears from the barn and while the group is looking for him Shane emerges from the woods claiming Randall has escaped and is armed. Glenn and Daryl are sent to look for him in the woods. They are attacked by a walker, and when Glenn kills it, it turns out to be a reanimated Randall. Both Daryl and Glenn are puzzled by the lack of bites on his body, and also find it strange how his neck had been snapped. They return to the farm to tell the rest of the group about what happened.

"Beside the Dying Fire"

With a gun to her head, he forces Glenn to drive back to Woodbury.

Glenn uses his feet to knock stuff on it, but eventually breaks the chair and stabs it. Merle comes back later with Martinez, and behind them Maggie is held topless by The Governor.

Glenn is later seen being taken care of by Hershel, and it also appears that there is tension between him and Maggie.

"Home"
Glenn proposes that the prison survivors defend themselves from The Governor by attacking Woodbury immediately, and inquires to Michonne about the town. Hershel, however, remarks that Glenn's decision to take over the leadership from Rick may be unwise at the time, due to Maggie still recovering from her and Glenn's detention and torture in Woodbury. He advises Glenn to comfort Maggie but Glenn first decides to search for the origin of the walkers with assistance from Carl. Glenn obliges to Hershel's request after completing this task. Upon talking to Maggie, he asks her why she is acting depressed, and she responds with explaining the abuse she endured from The Governor. He then asks her if she was raped, to which she responds with a "no," which relieves Glenn, but annoys Maggie.

He helps her escape, and when later asked why he would want her help, he responds that he needs it to find Maggie.

Glenn then proceeds to enter the tunnel and shines his flashlight at rubble. It is shown that walkers are stuck in the rubble, so Glenn begins investigating them. He is looking to see if one is Maggie. None of them are Maggie, so Glenn pulls out his knife along with Tara and kills them all. Glenn and Tara then proceed to climb over the rubble.

Once they get to the other side, Tara's foot gets stuck under a rock and it is shown that a herd of walkers are coming toward them. Glenn begins shooting at them and attempting to help Tara.

One by one, the four other survivors are brutally slaughtered over the pig trough. Glenn, being the next in line, is about to be executed as Gareth walks in and questions one of the guards about the survivors. This diversion led to Gareth getting in an argument with Rick over his bag of weapons, further delaying Glenn's execution. Gareth then orders for the murdering to continue, but once the guard prepares to knock Glenn unconscious, an explosion abruptly stops him, causing Gareth to flee. Rick breaks free from his cuffs, kills the guards, then sets Glenn and the others free. The four soon discover that Terminus was planning to butcher them and use their corpses for food. Rick orders them to not put down the guards and kill any Terminus member on sight.

The four fight their way back outside, and Glenn convinces Rick to unlock a container with a survivor inside as an attempt to keep their humanity. However, the survivor is half-crazed, and eventually stumbles into a walker, which promptly eats him. Glenn appears shocked, but continues fighting through Terminus until the group reaches Boxcar A, where they free the remaining survivors. Maggie is extremely relieved to see Glenn alive. Glenn then leaves Terminus with the group, and is happy to be reunited with Carol, Tyreese, and Judith.

"Strangers"
Glenn is seen with Maggie and she embraces him. Whilst on the move the next morning, the group hear screams for help. They go and assist the man from a group of walkers. He introduces himself as Gabriel. He takes the survivors back to his church, which they quickly check is secure and not a trap. It's then decided that the group will need to go and fetch supplies. Glenn goes with Maggie and Tara to scavenge a weapons store, where he finds three silencers in a mini fridge. After Rick, Michonne, Gabriel, Sasha and Bob return from the food-bank with a lot of supplies, the group celebrate with a big supper. Glenn listens on as Abraham makes a toast to the survivors and expresses his desire for them to come with him to Washington D.C. Rick agrees to do so, and the group all laugh and celebrate.

"Four Walls and a Roof"
When Rick, Tyreese, and Sasha come back inside the church after failing to find the missing Bob, Sasha wants to know where her people are, so she angrily confronts Gabriel. Rick steps in when she threatens to become violent, but he also confronts Gabriel, who confesses that he survived by refusing to take in people who needed his help. Glenn stands by the window and reveals that there's somebody lying on the grass outside. They rush out and find Bob with his leg missing. They carry him inside and Bob reveals what Gareth and his people did to him. Sasha insists that somebody fetch the first aid kit, but Bob tells her to save it, and reveals he was bitten at the food-bank. Sasha, Glenn and the others are upset, but they prioritize on making Bob comfortable. Glenn mentions Jim to Rick and reminds him that he lasted two days before they left him.

When Abraham announces that he's taking Eugene and leaving to ensure his survival, an argument breaks out between him and Rick when he insists on taking the bus. Glenn manages to stop this confrontation from turning violent by promising Abraham that if he stays for one more night to help deal with Gareth, then he and Maggie will leave with Abraham the following morning. Abraham reluctantly agrees.

Rick leads a group, which includes Glenn and Maggie, as they leave for the school to confront Gareth, who waits until they're gone and then breaks into the church to ambush the people left behind. Rick and co turn the tables on Gareth and Glenn, Maggie and Tara watch on in horror as Rick, Abraham, Sasha and Michonne brutally kill Gareth and his people.

The following morning, Glenn and Maggie say goodbye to Bob, who passes away shortly after. Abraham then decides it's time to go. Glenn bids farewell to Rick and gets on the bus with Abraham, Eugene, Rosita, Maggie and Tara, as they depart for Washington.

"Self Help"
Abraham and his group are driving down a road in the bus as they journey to D.C. Glenn humorously questions Eugene about his hair. The bus suddenly breaks down and crashes when it collides with another car and flips. Everyone is safe but the group are forced to fight off the surrounding walkers, with Glenn and Abraham first out the bus. When it's suggested that they turn back to the church, an enraged Abraham refuses. Glenn agrees that he'll do whatever Abraham wants, as he's with him. The group end up in a library and fortify it for safety. Glenn has a talk with Abraham, where he thanks him for coming with him. Glenn suggests that Abraham fix up his hand. Glenn then heads to bed with Maggie, where he asks her if she's thinking about the church.

The next day, the group find a firetruck to use to get to Washington. When Abraham moves it forward, walkers begin pouring out of the warehouse behind. Glenn kills a few before Eugene turns on the fire hose to deal with the rest. Glenn mentions that there's a goodwill store where they might be able to get some supplies but Abraham is eager to go. When they stop again, Glenn watches the perimeter. He then complains about the smell. The group walks down the road and discovers an enormous herd of walkers. Glenn suggests a detour around but Abraham adamantly refuses, much to the groups objection. Abraham grabs Eugene to take him back whilst the others try and stop him. When Tara tries to stop Abraham and he pushes her away, Glenn tells him that enough is enough. Abraham is about to get violent with Glenn when Eugene confesses he's not even a scientist and that he lied in order to be protected and survive. This stuns Glenn and the others tremendously. Abraham responds in rage and violently punches Eugene several times. He collapses to the ground and Rosita is forced to intervene and threaten Abraham with her gun. He stumbles away and collapses to his knees in grief as Glenn and the others try and rouse Eugene.

"Crossed"
After Eugene's bombshell and subsequent attack at the hands of Abraham, he remains unconscious and in a critical condition. Abraham is also non-responsive and he shuts himself off. Glenn and the others take charge, with him, Tara and Rosita going to fetch water while Maggie stays behind to watch over Eugene. Rosita shows Glenn and Tara how to make a water filter using a bottle, as Eugene taught her to do. Rosita tells the story of how she ended up accompanying Abraham on his mission. Glenn spots ripples in the stream, caused by a fish. Glenn and Rosita construct a make-shift net which they successfully use to catch the fish. Glenn tells Rosita the group will need her skills and he asks her if she's up for staying with him and the others, no matter where they end up. She confirms she is. Tara interrupts the conversation when she happily shows them a yo-yo she found. With food and water, the trio make their way back to Maggie, just as Eugene begins to come round.

"Coda"
With Abraham back in action, the group make their way back to the church just in time to save Michonne, Carl, Judith and Gabriel from a big group of walkers. Maggie and Michonne embrace one another and Maggie is ecstatic and emotional when she learns that Beth is still alive and Rick and the others have gone to rescue her. Tara suggests they go and join them, which they do.

After arriving at the hospital where Beth is being held, they arrive as Rick and the group are leaving. Maggie is evidently excited, but is crushed when she sees a tearful Daryl carrying Beth's corpse. Maggie drops to the floor in horror and sobs hysterically, as Glenn attempts to comfort her.

"What Happened and What's Going On"
After Beth's funeral, Glenn ran for a supply run alongside Rick, Daryl, and Sasha. He covered Rick when the latter checked an abandoned truck, but found nothing. Later on, after Rick decided to set Noah's community as their next destination. A walled community with 20 people in it. Glenn paid attention to what Rick said that despite the place is far away, if it turns out to be right, then they had to take the journey. Glenn asked Rick what if the place is not there anymore, not believing there's any hope to settle in anymore. Rick talked him out of it by telling him that they gonna keep moving on, before being added by Michonne who said, "then we'll find a new place."

"Them"
Glenn appears when Maggie, Daryl, and Sasha came back from the woods. While they were driving they ran out of gas and they all start walking. Then Glenn and the others stopped when they see tons of walkers then they all started to kill them all. Then the others continue to walk when they spotted some cars. Then Glenn came up to Maggie and she saw a walker in the trunk then he opened the trunk and killed the walker. Then the group was relaxing when 4 dogs came out of know where, then Sasha killed them and they all had a barbecue. Then they kept moving then Glenn wanted to give Daryl some water but he didn't want it. Then the group found some water then Eugene tried to take a sip, but Abraham knocked the bottled of water of his hand, then they all hear thunder and lightning and then a tornado formed, but Daryl said, he found a barn then they searched the barn. Then at night Rick made a speech about his grandpa when he was in war, then he said a few words that we are The Walking Dead. Then Glenn got up and help his group to stop the walkers from breaking in, but it was all a dream.

"The Distance"
Glenn goes with Abraham, Maggie, Michonne and Rosita to check for Aaron's vehicles. He drives the car during the night run with Michonne, Rick and Aaron. When they hit a herd and crash through many walkers, the car gets stuck from guts in the engine. Aaron sees a flare and runs off after it, leaving the others to follow him. Glenn gets separated but fights off the walkers, eventually finding and saving Aaron, who then helps him save Rick and Michonne. When they meet up with the rest of the group and Aaron's boyfriend, Eric, Glenn tells Rick that everything is going to be fine if he lets the couple stay with each other. He then repairs the RV when it breaks down near D.C. He is then seen departing the RV as they arrive at Alexandria.

"Remember"
Glenn is the first through the gate into the Alexandria. In his interview he states that the group were almost out there too long. Aiden Monroe and Nicholas meet with Tara, Glenn, and Noah in order to train them as runners for future missions. While out in the woods, Aiden explains to the newcomers that they are to follow his instructions. They soon approach a bloody rope used to restrain a walker, which had escaped. The men start making loud noises to lure it, much to the dismay of Tara, Noah, and Glenn. When the walker emerges from the bushes, Nicholas and Aiden attempt to capture it. Tara tries to help, but the rotting walker proves too much, causing Glenn to step in and stab it in the head, angering Aiden. Back in town, Aiden confronts Glenn, which turns physical and ends up with Aiden being punched by Glenn until his mother, Deanna, steps in and orders Aiden to back off. Deanna thanks Glenn for punching her son.

"Forget"
Glenn appears at the party at Deanna's house. When Noah reveals that he is having doubts about his place in both the community and with them, Glenn he reassures Noah that he is family now.

"Spend"
Glenn is seen loading supplies into the back of a truck for a supply run. Maggie stands near behind, waiting to wave him off, along with Deanna and Reg Monroe, Aiden's mother and father. As Tara, Eugene, Nicholas, Noah and Aiden pile into the truck, Deanna thanks Glenn for keeping his son in line. Maggie bids her husband goodbye and they pile into the truck towards the warehouse.

Upon their arrival at the warehouse, Aiden was quick to point out their fastest route, in and out, before Glenn tells him that they should scout the perimeter to find all their exits if things were to go awry, to which Aiden agrees. Once their reconnaissance was over, the group discovers a group of around two dozen walkers behind a gate. Aiden, looking unnerved by the number of walkers, compliments Glenn's knowledge and strategies, and suggested they get to work. Glenn pairs off with Noah and they begin to look around for the object Eugene needs. When Aiden is cornered by an walker with a shield over its head, making it difficult for Aiden to kill it. Glenn quickly notices the grenade hooked to the walker and screams for Aiden to stop. Aiden impulsively continues shooting and accidentally hits a grenade attached to the walker's belt-pouch, throwing everyone back from the force of it. The fence that held the two dozen walkers behind at bay to collapsed and allowed them out.

Glenn notices Aiden pierced against the wall, but Nicholas pronounce him dead without checking. He quickly finds Noah and they search for Eugene and Tara first. Eugene calls out for them and they find Tara passed out on the ground. Walkers approach Eugene and Tara, attracted to her blood. Noah saves them and helps carry Tara. Glenn calls for them to take shelter in the office. When they are behind the closed doors, Nicholas meets up with them and is shocked when Aiden cries out. Eugene tells them to go ahead and save him while he protects Tara.

Noah launches a flare in the opposite direction from Aiden, drawing the walkers away. They try to save Aiden, only for Nicholas to freak out and run. Noah and Glenn are forced to leave Aiden behind as the walkers get closer and closer. They chase after Nicolas as he runs out through revolving doors, only for all three of them to get trapped in two different compartments with walkers cornering them from all sides. Glenn quickly puts a plan in action as Eugene drives by, blaring music and pulling walkers away from one side. He tells Nicolas to hold onto the door as he tries to break the glass. Nicolas freaks out again and pushes his way out from his side, allowing the walkers to have access to Glenn and Noah.

Noah's leg is grabbed by the walkers, and he trips. Glenn grabs Noah's hand and tries to pull him back, but Noah tells Glenn "Don't let go" and allows himself to be pulled out of the door. After a struggle, Noah is pushed against the clear glass, getting devoured as Glenn watches. Glenn cries as Noah is torn apart in front of him, and is devastated when Noah finally dies. Enraged, Glenn leaves the building and gets back to the van outside of the warehouse. There, Glenn finds Eugene on the ground after being thrown out of the van by Nicholas, attempting to leave them, and all evidence to his cowardice, behind. Glenn knocks him out and throws him into the back of the truck. When Eugene asks where Noah and Aiden were, Glenn just tells Eugene to watch Nicholas. They drive back to camp minus two members and a barely alive Tara. Eugene holds the unconscious Nicholas at gunpoint per Glenn's orders.

His voice is heard at the end of the episode when they arrive back at Alexandria as he screams out "Help!"

"Try"
Glenn tells Rick the truth about everything that happened at the warehouse during the supply run, while at the same time, Nicholas is telling the complete opposite to Deanna and placing the blame for Noah and Aiden's deaths on Glenn. Glenn finds Nicholas cleaning blood out from the back of the van and threatens that he is no longer allowed to go out on supply runs or leave with anyone else for their own protection. Glenn and Nicholas are both seen rushing to the town square to witness the fight between Rick and Pete.

"Conquer"
Glenn appears along Abraham and Carol when they visit Rick, who is healing from his sustained bruises from his fight with Pete before. When Rick hatches a plan to take over Alexandria, only if Deanna and the others are up against them, he quickly tries to cancel the idea. Later, Glenn meets with Maggie after she spoke with Deanna, trying to figure out what the night's meeting would be about. Maggie informs him it would be just as they thought it would, and that she believes that she can convince the community to let Rick stay. Nicholas stalks Glenn while he is with his wife, waiting for Glenn to be alone. Glenn tells Maggie that he loves her before separating to prepare for the night's gathering. Nicholas then lets Glenn see him climbing over the wall to lure Glenn out of the community, and Glenn follows. Once Nicholas felt he had led Glenn far enough away from the community, he shoots Glenn, but Glenn survives and escapes Nicholas's sight. Nicholas then follows Glenn's trail of blood until Glenn attacks him from behind. During the scuffle, Glenn severely damages Nicholas's leg, but Nicholas regains the advantage by exploiting Glenn's bullet wound. Before Nicholas could kill Glenn, a walker intervenes, forcing Nicholas to retreat. The walker attacks Glenn as more join to try and eat him. Nicholas leaves Glenn to die, and begins his injured walk back to Alexandria. After nightfall, a still alive Glenn attacks Nicholas again and breaks the latter's ankle. Glenn then punishes Nicholas for getting Noah killed by beating him down. Glenn nearly breaks Nicholas's jaw before he decides to just kill him. Nicholas, however, pleads for his life, making Glenn hesitate. Glenn repeatedly asks him to stop begging so killing him would be easier, but Nicholas does not listen. Glenn eventually spares Nicholas and helps him to his feet. The two wounded men head back for Alexandria.

"First Time Again"
Glenn first appears in this episode as a flashback. In a flashback Glenn and Nicholas show at the infirmary both bloody and bruised from their fight in the woods. Glenn is patched up by Rosita and Maggie asks him what happened. Glenn tells her that walkers attacked him and Nicholas in the woods and Glenn was accidentally hit by by a bullet that ricotched off of a tree and hit him in the shoulder. Glenn later appears at Rick's meeting where they discuss how to get rid of the walker herd in the quarry. Glenn tells Maggie that she should stay in Alexandria and watch over Deanna who is still devastated over the deaths of Aiden and Reg. Maggie tells Glenn that's not the only reason he wants her to stay and Glenn acknowledges this. Glenn notices Nicholas and looks at him in disapproval. Nicholas raises his hand and says he wants to help Rick with the plan as they are going to need all help he can get. After Glenn sees this he offers to go too likely to watch Nicholas. Glenn later appears with he and Nicholas helping to build the wall to lure the walkers away. Glenn notices Maggie and Tara hugging which he smiles at. Glenn and Nicholas are later seen at the hardware store they are assigned at to clear out. Glenn tells Nicholas that he will be keeping a close eye on him from now on. Nicholas tells him he just wants to help which Glenn says he can.

In the present, Glenn is seen at the quarry when the truck holding one of the walkers on the opposite side of the quarry begins to fall Rick tells everyone to get ready and get into their positions. Glenn with Nicholas and Heath begin to head off to the hardware store that they have to clear. They arrive at the hardware store that they have to clear out so the walkers inside will not distract the herd they are trying to lure away. Glenn goes around to the side and sees a door. Glenn says they'll let a few walkers out at a time so they don't get overwhelmed. Heath isn't so sure on the plan but Nicholas defends Glenn saying he knows what he is doing. Nicholas and Glenn begin to pry open the door but when they open it it's revealed that a shutter was keeping it closed. They go to the front of the store and Glenn says that he and Heath will break the glass while Nicholas stays on the side. Nicholas says he wants to help but Glenn tells him to stay off to the side and if things go bad to go and radio Rick. Glenn shoots the glass and the walkers begin to pour out. Glenn manages his side of the walkers but Heath struggles and is being overwhelmed. Nicholas steps in and saves Heath and Nicholas asks Glenn if he can kill the last walker which Glenn approves of. Glenn, Nicholas and Heath run off into the woods. Glenn, Nicholas and Heath begin to travel back to Alexandria when they hear a loud horn coming from Alexandria.

Relationships
{{Scroll-1|

Maggie Greene
"I care more about her than I care about me."

- Glenn to Daryl about Maggie.

Maggie and Glenn were tasked with going on a supply run shortly after the Atlanta group arrived on Hershel's farm. On the supply run, the two end up having sex, which Maggie regards as a one time thing. Later, she decides to have sex with him again but he stumbles upon walkers in Hershel's barn. Maggie asks him not to tell anyone, but he eventually tells Dale, causing Maggie to become upset. When Glenn and Maggie make another run into town for supplies, Maggie gets attacked by a walker but Glenn is able to save her and kill the walker. This, along with Glenn's convincing, helps the two begin to mend their relationship. Right before Glenn leaves with Rick to find Hershel, Maggie tells him, "I love you".

Their relationship went through another rough patch after the shootout at the bar. Glenn told her that he froze because she told him that she loved him, and he was afraid to die because of how it would affect her. She tries to embrace him, but he pushes her away. With the help of Hershel's approval, their relationship heals once again. When they leave Hershel's farm due to it being overrun with walkers, Maggie is distraught but is comforted by Glenn.

In the following three months, Glenn and Maggie continue to care and support each another. When Maggie begins thinking pessimistically about her father's chances of survival, Glenn makes her think more positively. Later on, Maggie and Glenn make a run into town to get supplies for Lori's daughter but get captured by Merle and taken to Woodbury. When The Governor brings Maggie into Glenn's holding room with her shirt off, he believes that she was raped and becomes enraged. Maggie gives up the prison's location when The Governor threatens to kill Glenn. She later assures him that she wasn't harmed.

Later while on watch, Maggie and Glenn have a talk and they are on good terms again, they kiss.

In "This Sorrowful Life", Glenn gives Maggie a ring cut off from the finger of a female walker outside the Prison after getting Hershel's blessing to marry her. Maggie accepts the ring, and the two become engaged.

As time passes, Maggie and Glenn take to calling themselves married. In "30 Days Without An Accident", Maggie believes she may be pregnant. She is somewhat disappointed to learn she isn't, and tries to convince Glenn that the relative safety of the prison makes having a baby more of a possibility, that she wants to live and not worry about dying.

Maggie's hope soon turns to hard reality when a mystery virus overtakes the prison. Glenn falls ill and is quarantined, separating him from Maggie. When walkers overwhelm the quarantine ward, Maggie helps save him and keep him stable until others arrive from a trip to find medicine. Glenn begins making a recovery.

Unfortunately, as Glenn is still recovering, The Governor attacks the prison. Maggie puts Glenn on a bus with most of the sick and elderly residents, but leaves the bus to look for Beth. By the time she returns, the bus has gone.

Maggie, who fled the prison with Sasha and Bob, becomes single-minded in her goal of finding Glenn, dead or alive, especially after she searches the bus (now full of walkers). She begins leaving messages written in walker guts for Glenn to look for her on the way to Terminus.

Just as Glenn and Tara Chambler are about to be killed by walkers in a decaying tunnel, Maggie and her group find them. Maggie and Glenn have an emotional reunion, with Maggie burning the photograph he'd taken of her in the guard tower shortly before the virus hit, saying he'll never need a photo of her again.

They and the rest of their combined groups make their way to Terminus, where they are soon captured.

Rick Grimes
"What life I have I owe to him. I was nobody to Glenn, just some idiot stuck in a tank. He could have walked away, but he didn't. Neither will I."

- Rick to Daryl about saving Glenn.

Glenn meets Rick when he is most in need and near suicide, left alone in the tank after his horse went down in downtown Atlanta. Despite much sarcasm against Rick, Glenn saved his life and would begin to see Rick's boldness surpassing his very own before introducing him to the Atlanta camp, ultimately reuniting him with his family. As time went on, Glenn became Rick's backbone of the camp and during their journey to the Greene farm. Despite learning of Lori using Glenn as an errand-boy to pick up Plan-B pills, Rick continued to acknowledge it was not his fault and later showed distress in constantly using the young man as a runner. When Hershel relapsed following the barn shoot-out, Glenn followed Rick into the town's bar where they found the Greene patriarch and Rick proceeded to lead him out of his dilemma. However, the very same trusting behaviour he showed Rick went on to betray him as he was forced into a shoot-out with the others. After the fallout of this incident, Glenn continued to follow Rick blindly up until Maggie and himself were forced to abandon her father's farm. They eventually found the survivors of their group, including Rick, who admitted that they were all in infected with the mysterious zombie virus. This caused Glenn to doubt Rick, though it was later shown to have subsided after surviving with him side-by-side after many months under his leadership. Glenn even went as far as to try and calm Rick's disturbed reaction to Lori's death by attempting to bring him back. Met with hostility, Glenn subsided and allowed Rick to remain the way he was in hopes he would return to normality some how. Rick risked his life to infiltrate Woodbury and in turn saved Glenn from being executed by the Woodbury soldiers along with Maggie. Their relationship starts to crack again, they have a heated discussion on the road after Daryl left them and Maggie tries to stop them, as Rick becomes unstable Glenn starts questioning his leadership, telling Hershel Rick is wandering in crazy town. Glenn, upset because Merle stayed in the prison with them, tells Rick he would have never asked him to live with Shane after he tried to kill him. By Season 4, their relationship appears to have stabilized.

Lori Grimes
"They were family."

- Glenn to Oscar and Axel, regarding the group's casualties, Lori included.

Glenn and Lori are good friends and look after each other during their stay at the Atlanta Camp. As the first to know about Lori's pregnancy, Glenn proves his friendship to Lori by offering to ride into town to retrieve helpful medical supplies, at the personal risk of a walker attack. He also provides wise advice for her to talk to Rick about the pregnancy, which she is grateful for. Lori was okay with Glenn telling Dale about her pregnancy because she felt that she should not have put Glenn on the spot and that they were friends. After Lori's death in Season 3, Glenn cared for Lori so much that he and Maggie would care for her baby, Judith.

Carl Grimes
"Carl, you and I will go down to the tombs. We need to figure out where the breach is."

- Glenn to Carl.

Carl and Glenn are good friends during their stay at the Atlanta Camp. As time goes on Carl and Glenn have established a brotherly like bond. On several occasions, Glenn helps to look after Carl for Rick and Lori, and cares for his well-being. While discussing his plans to face the governor, Glenn asks Carl to help look for breaches in the prison, and is obeyed by him. Carl is happy to see Glenn return from Woodbury, and their friendship continues as normal.

Judith Grimes
"Back when you had two legs and we didn't have a baby crying for walkers every four hours!"

- Glenn arguing with Hershel about staying or leaving the prison.

Glenn cares for Judith and has been willing to go and retrieve supplies for her to ensure her survival. During the conflict with the Governor, Hershel tries to devise plans in avoiding The Governor by leaving the prison. Glenn saw Judith as a burden, and says that she will cry and become a major maintenance. He even says that she will bring walkers on them if they decide to leave the prison.

Shane Walsh
"Have I mentioned that I really like your new haircut? You have a nice shaped head."

- Glenn commenting on Shane.

Shane and Glenn are good friends and look after each other during their stay at the Atlanta Camp. As the temporary leader of their group, Glenn respects Shane and his leadership. During their stay at the Greene farm, the group finds a walker in one of the water wells, and decide to use Glenn as live bait to hang a noose around its neck so that they could pull it out. Before heading down, Glenn tells Shane that he likes his haircut, while Shane assures him they will get him out alive. After the walker attack at the farm, Glenn and the others reunite at the highway and is saddened when he learns of Shane's death. Glenn is shocked to learn of Shane's betrayal and plan to kill Rick, and loses any respect he had for him.

Merle Dixon
"He tied me to a chair, beat me and threw a walker in the room. Maybe I can call it even but he..... He took Maggie to a man who terrorized her! Humiliated her! I care more about her than I do about me!"

- Glenn telling Daryl why he cannot forgive Merle.

Glenn and Merle didn't get along well during their time in Atlanta and the campsite, as Merle was unwilling to co-operate with the others. He also declared himself in charge, which angered Glenn and the rest of the group. Glenn showed little regret or remorse for Merle being left behind in Atlanta and reluctantly went along on the rescue mission to free Merle from the rooftop. Much later, Merle captured Glenn and Maggie and took them to Woodbury, where he interrogated Glenn on where the remaining Atlanta Survivors were located, including Rick. Merle attacked and beat Glenn continuously and even went as far as bringing in a walker to attempt to persuade Glenn to talk. Glenn and Maggie gave up the location of the prison but then shortly afterward, Rick, Michonne, Oscar, and Daryl breached Woodbury's walls, rescuing Glenn and Maggie although Maggie revealed the location of The Prison. When Rick and Maggie returned and rescued Daryl and Merle Dixon, Glenn tried to kill Merle showing a negative relationship however he was stopped by Daryl. Glenn was in full agreement with Rick in not letting Merle come to stay at the Prison, triggering Daryl to leave.

Later, after saving Rick from dying, Merle was allowed to enter the Prison, a decision Glenn did not agree with, and later he tried to convince Rick to give Merle up as a bargaining chip to The Governor, showing that Glenn had developed a severe hatred of Merle for his actions towards him and Maggie. Merle apparently showed no regret or remorse for what he did to Glenn and Maggie, which may have contributed to Glenn's dislike of him.

Later on, Merle decided to go to the meeting between Rick and The Governor in order to kill The Governor, but Glenn would not allow him to go, triggering a fight between the two in which Merle almost stabbed Glenn before Beth broke it up. Thus strengthening Glenn and Merle's bad relationship.

In "This Sorrowful Life", Daryl questioned Glenn if Merle had apologized for his actions, but Glenn shook his head. Daryl promised Glenn that Merle would apologize eventually, but Glenn, in turn, needed to show some forgiveness. Glenn responded that he could've forgiven Merle, had he not given Maggie to The Governor who, in turn, humiliated her. Glenn still no doubt dislikes Merle, has not forgiven him, and most likely does not show any remorse for Merle's death at the hands of The Governor.

Daryl Dixon
"You've got some balls for a Chinaman."

- Daryl to Glenn.

Glenn and Daryl didn't get along well during their time in Atlanta and the campsite, but as time goes on they have established a good friendship. At first, Daryl had a more racist view of Glenn, calling him a "Chinaman" while looking for the bag of guns and also calling him Short Round (The Chinese character from Indiana Jones and The Temple of Doom). Daryl has grown out of his prejudice stage and has accepted Glenn for who he is and proved it by having Glenn come with him to search for Randall and praises Glenn's skills after he kills a zombified Randall. Although Daryl cracks about Glenn's driving, Daryl and Glenn get along real well and they have made quite a team. Daryl was impressed of Glenn's recovery from the flu, and praises him, saying that he is a tough son of a bitch. During season 5, their friendship is always genuine and stable.

Dale Horvath
"I let him down."

- Glenn to Andrea regarding Dale.

Glenn and Dale are good friends and look after each other during their stay at the Atlanta Camp. Glenn had a true friendship with Dale, frequently asking for advice and helping him fix the RV when Jim died. Dale is the first person Glenn talks to regarding his sexual encounter with Maggie, he also tells Dale both Lori and Maggie's secrets revealing the level of trust he had for him. Glenn saw Dale as a mentor type figure. Dale's death hit Glenn hard when he and Andrea were attempting to fix the RV, with Andrea telling him that Dale would be proud, this resulted with Glenn breaking down in tears as he reflected on how Dale was a true friend. In the episode The Distance, Dale is silently remembered by Glenn.

Andrea
"He was proud of you. Maybe not in that moment, but overall."

- Andrea to Glenn regarding Dale.

Glenn and Andrea are good friends and look after each other during their stay at the Atlanta Camp. During their supply run in Atlanta, Glenn appreciates Andrea and they often work together, showing an amount of trust between the two. During their time at Atlanta and the Greene farm, Glenn and Andrea work with each other to ensure the group's survival, thus strengthening their friendship. After Dale's death, Glenn helps Andrea repair the RV, and tells Andrea he let Dale down. Andrea consoles Glenn, and tells him that Dale was always proud of him. After the walker attack at the farm, Glenn and the others reunite at the highway and is concerned for her when she isn't present. When Andrea arrives at the prison, Glenn is shown to be not trustworthy of her anymore and aggressive towards her. Glenn refuses Andrea's offer to stay with the governor at Woodbury, and insists on engaging Woodbury. Glenn is saddened by Andrea's death.

Carol Peletier
"You know my friend Glenn? He's the best tucker I know. And he'll make sure that you feel toasty and warm, okay?"

- Carol to Lizzie regarding Glenn.

Carol and Glenn are good friends and look after each other during their stay at the Atlanta Camp. Glenn shows concern for Carol due to her being unable to defend herself from walkers, and protects her whenever he can. When Sophia goes missing, Glenn assists Carol in finding her. Glenn is saddened and sorry for Carol when Sophia's fate is revealed, and constantly looks after her. After Hershel is bitten, Glenn is thankful towards Carol for assisting in saving him and appreciates his medical skills. Later, Carol asks Glenn for a favor which involved helping her kill a female walker so she can practice performing a C-Section as she may have to be the one to deliver Lori's baby due to Hershel's current condition and because of Carl being born that way, which improves their friendship.

Sophia Peletier
"Y'now, maybe in some weird way this is for the best. At least we know and now we can move on. Yeah, it's just like... It meant so much to everyone-- finding her, y'know?"

- Glenn regarding Sophia.

Glenn seems to care a lot about Sophia and the other children at the Atlanta camp, and cares for all of them. After Sophia's disappearance, Glenn helps by scouting out routes to search for Sophia on a map. He also physically searches for Sophia on certain occasions. After the discovery and death of Sophia, Glenn states that finding her was important to the whole group.

T-Dog
"When the evacuations started, T-Dog drove his church van to the home of every senior he knew just in case they needed a ride. He saved my ass on a thousand occasions. He wasn't just a good guy... he was the best."

- Glenn to Hershel regarding T-Dog.

Glenn and T-Dog are good friends and look after each other during their stay at the Atlanta Camp. During their supply run in Atlanta, Glenn appreciates T-Dog and they often work together, showing an amount of trust between the two. When T-Dog gets beaten by Merle, Glenn attempts to intervene the fight. During their time at Atlanta and the Greene farm, Glenn and T-Dog work with each other to ensure the group's survival, thus strengthening their friendship. After T-Dog's death, Glenn is devestated, and tells Hershel that T-Dog gave survivors a ride to safety in his church van and says that he was a good man who saved many lives. Glenn cared for T-Dog so much that he believed that Rick and the group should have killed the prisoners at first sight.

Jim
"Think I'm in this by myself? You can't take us all. There's too many of us. We've been on the road, not hiding in some dungeon. Rick, Shane, Dale, Jim, Andrea."

- Glenn to Merle.

Glenn and Jim barely interacted, though Glenn and Jim had some of the same interests such as cars. After the group lay Jim by a tree so that he could reanimate and be with his family, Glenn was saddened and gloomy. While being interrogated by Merle, Glenn honors Jim by telling Merle that the group is strong and that Jim is still with them.

Hershel Greene
"You're like my own son."

- Hershel to Glenn when treating his wounds.

Hershel and Glenn initially don't have a very good relationship, with the former disapproving of his relationship with his daughter, Maggie. But as the time passes, Hershel realizes that Glenn is a capable man who can care and protect his daughter from the dangerous world they live in. He gives Glenn a pocket watch (which has been passed through generations in Hershel's family) and along with it permission to be with Maggie.

Later on in the prison, Hershel tells Glenn that he is like a son to him, showing their extremely close bond and friendship. When the Prison is overrun by Walkers after a delivery van driven by a Woodbury soldier unloads them during the Woodbury attack, Glenn (along with Michonne) helps to rescue Hershel. Glenn later confronts Hershel telling him he wishes to marry Maggie. Hershel happily agrees, saying "You have my blessing."

When Glenn falls ill from the mystery virus spreading throughout the prison, he still helps Hershel and Sasha with the other patients in quarantine until he becomes too weak to do so. Hershel works tirelessly to save him, to the point where he pleads with Maggie not to kill the walker who is about to kill him, as the walker is wearing intubation that he can use for Glenn. Maggie manages to kill the walker without damaging the mask, and Hershel stabilizes Glenn until Michonne, Tyreese, Bob, and Daryl arrive with medicine.

Glenn is ill and/or unconscious throughout the fall of the prison, meaning he knows nothing of Hershel's capture or death. When he comes to and gathers some supplies and mementos from the abandoned prison, one of the items he takes is Hershel's watch. When Tara, a member of the Governor's militia, accidentally tells him about the murder (mentioning an "old man" the Governor killed), Glenn asks if she means Hershel. Upon getting confirmation, Glenn is devastated. He comments that he was a great man and taught him to keep hoping, showing that his father-in-law's message has been passed down.

Beth Greene
"Why don't you go check on Beth? Go on."

- Glenn to Maggie about checking up on Beth.

Glenn cares for Beth due to her youth and the fact that she means the world to Maggie and Hershel, and looks after her from time to time. Before they arrived at the prison, it is presumed that they started caring deeply for one another like siblings. Following Glenn's return from Woodbury, Beth is glad to see both him and Maggie again. After Glenn and Maggie's marriage, Glenn's relationship with Beth has improved, and is now her brother-in-law. Beth would sometimes write about Glenn and Maggie's happiness together in her diary, explicitly stating that she believed that they would grow old together. Glenn was visibly shocked and saddened when he discovered Beth had been killed.

The Governor
"Get the hell out of here!!!"

- Glenn to The Governor during the attack of the prison.

Philip is one of the few people in the series that Glenn has an extreme dislike for, mainly for what he did to Maggie during their kidnapping. Philip had Merle interrogate Glenn while he bluffed raping Maggie in an effort to divulge the location of the Prison. After Rick and Maggie attack Woodbury, Glenn is angered at Rick for not killing The Governor during the attack and instead focusing his efforts on rescuing Daryl, who had been taken by Woodbury while covering the others as they escape. He was eventually able to let go, to the point where he didn't shoot him during the Woodbury Army's assault.

Michonne
Glenn and Michonne showed signs of distrust when they first met outside of Woodbury. However, by the next day, they were both untied in their desire to kill Merle, which strengthened their bond slightly. Glenn vouched for Michonne when Daryl returned to the prison and questions arose about why they let Michonne in and not Merle. After Merle had left the prison, both Glenn and Michonne showed little regret towards his death.

The two of them became prominent supply runners for the prison after the disappearance of the Governor. Glenn and Michonne worked together in raiding the superstore shelter, though they did not scavenge for supplies together. Once they returned the prison, however, their interactions became minimal due to Glenn being quarantined from everyone not infected by the influenza at the prison. Michonne volunteered to go to the college to search for medicine that would help treat those who had fallen ill, Glenn included.

Glenn was separated from Michonne when the prison fell, and only wanted to find Maggie when he woke up. Thus, he was willing to leave his entire group behind for the sake of his wife. After he found her, he suggested going to Terminus to see if any of their group had arrived there. Glenn was understandably not too excited and quite disappointed when he was reunited with Rick and Michonne, as he believed that the residents of Terminus would kill all of them.

Glenn and Michonne had little interaction throughout Season 5, but they continued their friendship even when Glenn and Maggie left with Abraham for Washington D.C., where Glenn stated to Maggie that he missed everyone they had left behind. When they returned to the church where the two groups had split, Glenn and Michonne were happy to see each other again, and they left for Atlanta together.

Michonne and Glenn went with Rick, Tyreese and Noah to Noah's old community in the hopes of finding good people. Michonne was shocked to hear that Glenn didn't believe it mattered if people were good anymore, as they died just the same. She pleaded with them to go to Washington D.C. anyway, which Glenn hesitantly denied. When Rick told her that she was right, Glenn appeared indifferent, but supported his decision regardless. Glenn and Michonne worked together to steady Tyreese and carry him out of the ruined community, and both were saddened when he died.

Both Glenn and Rick were distrustful of the water left for them in the road, though Michonne was more worried about whoever was watching them. Glenn and Michonne volunteered together to search for the vehicles that Aaron had promised them, and they turned up positive results. The two rode with Rick at night for the community Aaron was directing them towards, showing that they were growing comfortable around each other. Glenn was grateful toward Michonne for saving him from the walkers when he ran out of bullets.

Michonne came to Glenn's aid when Nicholas attacked him and Noah, which Glenn appreciated. They both felt disgusted by Nicholas's lies to Deanna in an attempt to get Rick's whole group removed from the community. They ended Season 5 on fairly good terms.

Tyreese Williams
"Get him up!"

- Glenn to Rick and Noah, ordering them to help Tyreese.

Glenn accepted Tyreese and his group into the prison after first meeting them, and vowed to put in a good word for them with Rick. Despite Glenn's and Hershel's words, Rick still throws them out after remembering what the last result of trusting other strangers was.

When the prison members officially opened their doors to survivors, Glenn and Tyreese seemed to be on good terms, going on supply runs together, though Tyreese admits he went on the supply run for a different reason. Glenn separates Tyreese and Karen once he learns of her sickness. Glenn does not take sides in the argument between Rick, Daryl and Tyreese because he himself had fallen sick to the influenza at the prison.

Glenn and Tyreese do not interact for the rest of the season, but he shares hope with Sasha that he may still be alive, showing that he saw Tyreese as a strong individual.

Glenn and Maggie remain behind with Tyreese, Judith, Bob, Eugene and Gabriel, all of whom are horrified at Rick's orchestrated massacre of the remaining Terminants.

Glenn leaves with Abraham while Tyreese stayed with Rick, cutting off communication between the two for a large period of time. When Noah was to be brought back to his community, Glenn left his grieving wife to help Tyreese get him there. Glenn was shown to be concerned for Tyreese after seeing him bitten and amputated, and defended him from a horde of walkers at the gates. Glenn stood over Tyreese's corpse remorsefully at the end of Tyreese's life.

Sasha Williams
Although Glenn and Sasha have relatively little interaction, it is known that the two respect each other. When Sasha and her group first arrive at the prison, Glenn allows them to remain just outside their cell block and lets them bury Donna next to the other graves in the field. When someone else in their group suggested attacking Glen and taking the prison for themselves, Sasha denied him, citing that these people had welcomed them in. Glenn promises to vouch for them when Rick returned. Despite Glenn's and Hershel's words, Rick still forces Sasha and her group to leave.

Over the course of the following months after the Woodbury survivors fled to the prison and Rick welcomed Sasha back in, Glenn and Sasha went on numerous supply runs together, strengthening their bond. On one supply run to The Big Spot, Sasha and Glenn worked together to clear the entrance and rescue Bob from the walkers, although neither was successful in the attempt to save him.

Glenn and Sasha were both infected by the influenza and were quarantined together, although neither spoke as Glenn was always busy helping other sick victims.

When the two escaped Terminus, both opted to just leave the place behind instead of going back to kill them all.

When Bob was returned without one of his legs to Rick's group by surviving Terminus residents, Sasha brutally slaughtered Martin, which horrified Glenn.

Glenn expressed his regrets over Tyreese's death to Sasha, wondering if he could have done something more to save him.

Upon their arrival at Alexandria, the two did not easily adapt to the environment, but still tried to make it work within the community.

Bob Stookey
Bob was found by Glenn and Daryl before the start of Season 4. Though not much interacting between them is shown, Glenn saves his life, only for Zach to get killed instead. After a huge number of prison inhabitants had been sick, including Glenn. Bob volunteers to pick up medical supplies with Daryl, Michonne and Tyreese at a school. Bob contributes to the healing of Glenn who saves him from the influence when he gets to prison. Glenn is saddened by Bob's death.

Tara Chambler
Glenn and Tara, for now, have a very utilitarian relationship; they are companions because they need each other's help for survival. Glenn, though aware of Tara's participation in the Governor's raid on the prison, is not overtly hostile toward her and helped her escape the prison. Tara, guilty over helping destroy his home, is incredulous that Glenn would want her help but feels obliged to do so.Their relationship improves significantly in "Claimed"; Glenn seems to genuinely trust Tara by the end of the episode, and Tara even assisted him in getting Abraham to stop the truck so he could go back and look for Maggie. In "Us", realized wasn't the case. Tara is also shown to be feeling very guilty and in a great deal of debut to Glenn since even when she injuries her leg she continues walking and follows him into a dark and dangerous tunnel, in the tunnel she is trapped by fallen debris and the walkers move in, Glenn refuses to abandon her and fights off the walkers until they are rescued by more of the group. When Glenn is reunited with the others he decides not to mention Tara's involvement in the prison attack so that she can have a fresh start with them.

Abraham Ford
Glenn and Abraham started out pretty badly when Abraham was telling Glenn that Maggie was dead and that he should "do something with his life". This results in a fight, the noise from which attracts a horde of walkers. Due to Eugene accidentally shooting their truck's gas tank full of holes, rendering it useless, he, along with Eugene and Rosita, decided to follow Glenn and Tara to look for Maggie. During a conversation with Tara, Abraham reveals he has respect for Glenn, but believes saving the world is more important. Later, when Glenn apologizes for hitting him, Abraham jokingly tells Glenn that he isn't sorry for fighting Glenn due to his love for combat. Abraham ultimately forgives him. During season five, it is seen that their friendship is much stronger than before.

Eugene Porter
"Why the hair?"

- Glenn to Eugene.

Eugene seems to appreciate and has a neutral relationship with Glenn. Eugene decides he has to know if Glenn and Tara made it out of the tunnels alive and he tricks Rosita into going to the tunnel exit to find out. Glenn even gave him his own riot gear to increase Eugene's odds of surviving the journey to the capital. Even after learning about Eugene's lie, he still tries to protect him from Abraham.

Rosita Espinosa
"Try not to be an ass."

- Rosita to Glenn.

Glenn and Rosita have a relatively friendly relationship, their relationship likely developed further when Rosita gave Glenn the picture of Maggie he had taken back at the prison. Despite their relationship, Rosita yells at Glenn for not considering Tara's injury, calling him an "ass", however when Glenn and Tara are about to enter the tunnel, she gives him a goodbye hug and tells him to try not to be an ass. Lately, it is shown that they deeply respect each other.

Noah
"Don't let go!"

- Noah to Glenn.

Glenn and Noah did not know each other until after Beth's death. Although Glenn doubted that Noah's home was still intact, he still went for his sake, as well as to honor Beth, but was ultimately proven right. However, after arriving at Alexandria, the two became supply runners together with Tara, and became closer. Later, when Noah was sitting by himself at the welcoming party, Glenn and Maggie asked him to join, insisting that he is a part of the family. During a supply run, when Noah ends up being devoured by walkers due to Nicholas' arrogance, Glenn is highly traumatized and almost kills Nicholas out of rage for getting Noah killed, showing that he cared for him.

Aiden Monroe
"Hey... hey! Look, we got a way doing things around here-- it killed our friend! (...) Look, I'm not having this conversation. You will obey my orders out there! (...) Say that again. Come on. Come on, tough guy."

- Aiden to Glenn.

Glenn and Aiden met a few days after Glenn and his group entered Alexandria. They started off smoothly, and they respected each other, until Glenn started seeing how he deals with the walkers, one of which almost bit Tara. Aiden tried to warn Glenn how they do things at Alexandria, which Glenn disapproved of. Aiden asked his mother why she let Glenn and his group in before trying to punch Glenn in the face, only to be knocked to the ground in the attempt.

Apparently, Deanna's forced integration of Rick's group turned their relationship for the better, as the two seemed to listen to each other when raiding the warehouse. When inside, Aiden impulsively shot an armored walker several times, one of his gunshots hitting a grenade. Glenn tried to save him with the aid of Nicholas, but was unable to due to Nicholas' desertion. Glenn was then forced to try to save him alone, but Aiden told him not to because he did not want to get another person killed, revealing that he had gotten his last team killed. Glenn was dragged away by Noah shortly before the walkers killed Aiden, greatly saddening Glenn.

Nicholas
"Noah died because of you. And I tried to tell you how it is and how it has to be! And you try to kill me? (...) Shut up. (...) Shut up. (...) SHUT UP! (...) Shut up..."

- Glenn to Nicholas, trying to summon the will to kill him.

Glenn and Nicholas, upon meeting first, held a mutual respect for being capable survivors. They greeted each other graciously, and proceeded to follow Aiden on Glenn's first supply run with Alexandria. Before their supply run could begin, Nicholas and Aiden insisted on killing a walker that had devoured their friends, but found the walker out of sight. Glenn hastily ordered Nicholas to be quiet when he whistled to try and lure out the walker, but Nicholas did not stop. When Glenn killed the walker before it could be tied up, Aiden and Nicholas were outraged that the glory of killing the walker had been taken away. Later, when they returned to the community, Nicholas and Aiden were adamant that Glenn and his friends be removed from their positions and find new jobs. A scuffle between the runners (and Daryl) broke out, but was ended due to the intervention of Deanna. Deanna reprimanded Aiden and Nicholas and ordered them to be more open to Glenn's ideas since he had been gathering supplies longer than them.

After Deanna's forced integration of Rick's group, Nicholas and Aiden grudgingly accepted Deanna's order to listen to Glenn.

On their next excursion, Nicholas and Glenn were charged with escorting Eugene into a storage warehouse to find a power converter. Nicholas firmly established that they needed to be quick, so the runners should run in and exit through the front doors, but Glenn disagreed in favor of scouting the building first. After finding walkers surrounding the front doors, they returned to the back and went inside with Eugene and the other runners. After walkers inside the warehouse tried to get at them from behind a fence, Nicholas told everyone to just move on, to which Glenn agreed. After the explosion accidentally set off by Aiden, Nicholas pronounced Aiden dead without checking him. After Aiden cried out, Nicholas was hesitant to go back and save his "friend" from the walkers. When he, Glenn and Noah reached Aiden, they tried to remove him from a pair of metal bars that impaled him. Nicholas, in favor of saving himself, marooned the runners and tried to escape without them out the front door, which made Glenn upset. When Glenn and Noah caught up with Nicholas, they all became trapped inside of a revolving door. In spite of Glenn's plan to get everyone out, Nicholas panicked and opened his door first, causing the walkers to reach Noah and devour him. Glenn was distraught at Noah's death, and wholeheartedly blamed Nicholas. When Nicholas tried to escape without him and Eugene, Glenn beat him down, but brought him back to Alexandria regardless to face Deanna.

Nicholas blatantly lied to Deanna about Aiden's what had happened to Aiden, whence Glenn and he were both remanded to stay until she sorted out who was responsible, as they both told different stories. Once Glenn discovered Nicholas's lie, he confronted him on each of the people he had gotten killed, calling him a coward that should not have lived. He warned him to stay behind the walls for the rest of his life, but Nicholas did not heed his warning and snuck out of the community to retrieve a weapon he had stashed. He later stalked Glenn while he talked to his wife, waiting for an opportunity to lure him out of the community. He picked his moment and allowed Glenn to see him climb over the walls. He lured him far enough away from the community to kill him, and he shot Glenn in the shoulder. Glenn survived, however, and assaulted Nicholas while he was tracking Glenn. When walkers got involved in the violence, Nicholas ran, leaving Glenn for dead. While walking back to the community, Nicholas was attacked again by a still alive Glenn, where Glenn broke Nicholas's ankle. Blaming Nicholas for Noah's death, Glenn prepared to kill Nicholas for his cowardly actions, but Nicholas pleaded for his life. Not having the heart to kill a man just yet, Glenn stopped himself from killing Nicholas and instead picked him up. The two wounded men went back into Alexandria together.
