Eugene Porter (TV Series)

"The key to survival is allowing oneself to be shaped by the assigned environment. In doing so, a broad range of capabilities are acquired, allowing one to flip the script and use said capabilities to shape said environment for maximum longevity. I'm saying I'm in the process of said stage two. I've changed, adapted… I'm a survivor."

- Eugene to Abraham Ford about being able to stay alive

Eugene Porter is a main character and survivor of the outbreak in AMC's The Walking Dead. He and his traveling companions Abraham Ford and Rosita Espinosa were en route to Washington, D.C., before Eugene revealed that he had been lying about being a scientist. Eugene is an intelligent man whose skills in producing resources and intellect are much appreciated by the group. He is good friends with Abraham and Tara Chambler.

Personality
Eugene is aloof, eccentric, cultured, and highly intelligent. While a detriment to the group while on the road due to his cowardice and clumsiness, being neither "combat ready or for that matter combat inclined," Eugene's value is evident in his ability to build helpful devices such as water filters and batteries out of common items. He's extremely able to force locks. He likes reading books and he is shown to be interested in video games.

Eugene prioritizes his survival over anything else, even allowing multiple people to sacrifice themselves to protect him under the false belief that he was an important scientist. Despite his manipulative abilities, he does possess a will to do good when he can, and as he continues to survive, he begins to put into perspective the importance of his conscience, going so far as to expose his lie for the well-being of his new friends.

Over the course of the second half of season 5 and the entirety of season 6, Eugene slowly begins to develop his skills as a survivor, and his courage. While this is slow at first, it is only when the survivors fight back against the herd in Alexandria that he truly shows he has developed the courage and skills needed to survive. This evolution continues after the time jump, and he shows his courage and newfound skills to survive when he is taken hostage by Dwight and the Saviors, and gives the other survivors the opportunity to fight back.

Houston, Texas
Very little is known about Eugene's life before or as the outbreak began. Eugene lied about who he was, stating that he worked on a Human Genome Project with nine other scientists, dealing with research on how to combat diseases with other diseases.

He is seen to be an avid fan of video games. He is also seen to have knowledge of dinosaurs, as he mentions that no one can know for sure if the zombie disease didn't cause the extinction of the dinosaurs; though it was most likely a joke in attempts to impress Tara Chambler. While his occupation prior to the outbreak is unknown, he appears to possess a vast amount of knowledge of many different areas, and is well read.

Post-Apocalypse
Eugene somehow survived the onset of the outbreak, and eventually came across Abraham Ford, who saved him from walkers. Seeing the opportunity of being protected, he lied to Abraham, pretending he was a scientist who knows what caused the epidemic, and that he was on a mission to go to the capital, where supposedly he could reverse the effects of the plague and restore order to the world. Eventually, they were joined by Rosita Espinosa and several other survivors, who traveled from Houston to northern Georgia, losing several members on the way.

"Inmates"
After Glenn Rhee collapses from fighting off walkers, Tara Chambler uses the end of the latter's gun to kill the remaining walker. While she does so, they pull their truck up to her. After Tara sarcastically thanks them for their help, the trio exit their truck, to which Abraham tells her that she has "quite a mouth," then asks about what else she has.

"Claimed"
Attempting to stop Glenn from leaving the convoy, Abraham reveals that Eugene knows what caused the outbreak and is escorting him to Washington D.C., but does not give any additional information about the mission. A fight between Glenn and Abraham alerts walkers in a nearby cornfield, Eugene attempts to alert them about the danger, but is unsuccessful. Eugene gets an automatic firearm from the truck, and due to him being inexperienced with using firearms, he shoots a hole in the truck's gas tank. The rest of the group finish off the walkers, and due to the truck now being useless, Abraham, Rosita, and Eugene leave with Glenn and Tara to look for another vehicle to complete their mission.

"Us"
Eugene is seen with Rosita, Abraham, Glenn and Tara as he talks to Tara about video games as they walk down the railroad, and she hands him a metal object that he remarks can be used for a homemade battery. The group comes across a building where a walker is just about to fall on top of Eugene until Abraham shoves him out of the way, knocking Tara down in the process. Eugene is given Glenn's riot gear for protection as part of a deal to Abraham so that they can keep going forward towards Terminus in search of Maggie. As the group parts ways with Tara and Glenn at the train tunnel, Eugene tells Tara that he found her hot, even though he was aware of the fact she was a lesbian. Eugene, Abraham and Rosita find an abandoned van on the street, with Abraham killing the walker inside. Eugene expresses concern for Glenn and Tara, although both Abraham and Rosita press on that Glenn and Tara are not their priority. As Abraham sleeps in the back, Eugene gives Rosita directions which ends up bringing them on top of the train tracks to the area where Glenn and Tara would exit according to his calculations. He reveals that the trio's origin point was Houston, Texas and that they spent a long time making their way across the country, eventually ending up in Northern Georgia. Their convoy was also bigger, and they had lost 8 people along the way. Eugene spots Bob Stookey, Maggie Greene, and Sasha Williams while Rosita and Abraham argue over her stopping the van for Eugene. Together, the six of them are able to rescue Glenn and Tara from a herd of walkers. Eugene, Rosita, Abraham, Glenn, Tara, Bob, Sasha and Maggie find Terminus and are greeted by Mary, who offers them something to eat and welcomes them to Terminus.

"A"
Eugene appears in the train car at Terminus when Rick Grimes, his son Carl, Michonne, and Daryl Dixon enter.

"No Sanctuary"
Eugene is seen to be trapped in the train car with the rest of the group, who are all making makeshift weapons. The group is then ordered by the Terminus residents to go to either side of the car. Expecting the residents to come through the side door, the group readies themselves to fight their way out, however, the Terminus residents open a top door and drop a flash-bang grenade into the car, disorienting the group and taking Rick, Bob, Daryl, and Glenn to be butchered.

Later, the group left in the car hears the explosion set off by Carol Peletier, Eugene sets up a charge by the train car door in case no one is there to let them out.

Sasha then demands to know what the cure to the outbreak is. After continued attempts by Abraham and Rosita to deter her questions, Eugene admits that he was part of the Human Genome Project, and that he may know a way to reverse the outbreak in Washington, D.C..

Rick and the other three, having escaped the butchers, free the rest of the group and fight their way out of Terminus, jumping the fence. Eugene is not a good fighter so tries to stay away from conflict. When a walker tries to grab him he swerves and lets Sasha deal with it. Eugene, Abraham, and Rosita are seen leaving Terminus with Rick's group, after meeting up with Carol, Tyreese Williams, and Rick's infant daughter Judith.

"Strangers"
Eugene is seen to be traveling with Rick's group, when they happen upon a man in distress in the woods, who reveals himself to be Father Gabriel Stokes. He and the group are lead to Gabriel's church, in which Abraham coaxes Rick and his group to travel to Washington DC with them during dinner. Rick agrees.

"Four Walls and a Roof"
When Abraham and Rosita hear that they're being watched, they wanted to leave the Church, and continue their journey to Washington. Abraham tells Eugene to get up, however he refuses. Being told once more, Eugene finally gets up before walking towards the church doors, before Rick says they can't take the bus, in which Abraham and Rick begins an argument over. Abraham gets aggressive, and Rosita tries to stop him. When Tara, Maggie and Glenn tells them that they're going with them if they just wait 12 hours. Abraham agrees with the plan, and they stay. When Rick and the others are on their way to slaughter the Hunters, Eugene stays at the church where he sits behind a desk. When Gareth and the Hunters get in the church, he mentions Eugene's name knowing he is there. Right before the Hunters break into the room they're staying in, Rick comes back and saves them. The next day, Rosita, Abraham, Eugene, Maggie, Tara, and Glenn head to Washington, D.C..

"Self Help"
Eugene is first seen in the bus thinking about what Gabriel had been saying at the church. Maggie then asks him how long it'll take to stop the walkers, where he explains a number of factors contribute. He tells Glenn he likes his own hair and his old boss T. Brooks Ellis loved his hair. The bus then breaks down and flips over a car. Eugene is okay but walkers arrive at the bus. Everyone except Tara and Eugene jump out to kill walkers. Eugene is trapped inside by a walker but Tara kills it, tells him to 'get brave' and hands him a knife. They leave the bus and Eugene is petrified and doesn't help. But when he sees a walker about to kill Tara he stabs it and saves her. After the fight, Abraham is concerned about Eugene but he tells him hes is fine. Eugene suggests heading back to the church but Abraham insists on continuing. Before leaving, he spits on the walker that was going to kill Tara. Eugene is next seen watching Abraham and Rosita have sex, where it is suggested he does it a lot. Tara comes and tells him she's grateful to him for saving her life. He confesses he sabotaged the bus and no one would keep him around if he couldn't save the world. Tara says they would because he's her friend.

The next day when the group are attacked, Eugene uses a fire hose on top of a fire truck to save everyone. The group continue down the road and Eugene is seen reading 'The Shape of Things To Come'. Maggie comes over and tells him she thinks he has the mullet so its not like he is like everyone else. When Abraham insists they go through a herd of walkers, Eugene is dragged by him. The others try to stop Abraham until Eugene screams that he's not a scientist. Everyone is shocked. Eugene tells them he just knows things and is a good liar. Rosita guilts him by telling him people died trying to get him here, including Bob. Abraham begins to assault Eugene, eventually knocking him out and causing him to crack his head on the concrete.

"Crossed"
Eugene is unconscious throughout the episode as a result of Abraham's beating. At one point, Maggie uses a ladder and a blanket to shield Eugene from the sun. He regains consciousness at the end of the episode, as he is heard making moaning noises.

"Coda"
Eugene is seen unconscious in the back of the fire truck when Abraham, Rosita, Eugene, Tara, Glenn, and Maggie return back to Father Gabriel's church.

"What Happened and What's Going On"
Eugene appears when he listens to Rick explains the camp Noah was talking about, then in the end he watches the group burying Tyreese and Gabriel speaking.

"Them"
Eugene is with the group on their long trek. When "a friend" leaves them water and the others don't want to risk it being poison, Eugene tries to drink some but Abraham swats it away. He helps keep the barn doors closed when walkers attack.

"The Distance"
Eugene watches as the group deals with Aaron, a supposed recruiter for a community called the Alexandria Safe-Zone. He then goes out to guard the perimeter. He rides the RV on both legs of the journey to Alexandria, playing cards on the table with the others.

"Remember"
Eugene enters Alexandria with the rest of his group and is interviewed by Deanna Monroe, leader of the Safe-Zone, where she assigns him to work on the solar arrays that help power the town. He can be seen residing in the house with everyone during the first few nights of their stay in Alexandria. When Glenn and Deanna's son Aiden get into a brawl at the town gate, Eugene can be seen watching among the townspeople.

"Spend"
Eugene is tasked with helping Glenn, Tara, Noah, another supply runner Nicholas, and Aiden find components of a power grid in a nearby warehouse. Due to his acknowledged cowardly nature, Eugene becomes reluctant to take part in the assignment and even more reluctant to carry a gun, but he is forced to join them because he is the only person who can identify what the group is looking for.

While at the warehouse, Eugene finds the parts of the power generator with Tara, but the supply run goes awry when Aiden accidentally shoots a grenade on a walker, causing an explosion that frees all of the other walkers in the building. Although Eugene is unharmed, Tara is knocked unconscious and suffers massive head trauma. When a walker approaches them, Eugene tries to kill it, only to be attacked by another from behind, and saved by Noah. After the group brings Tara into an office to check her wounds, they discover Aiden, whom they presumed dead, is still alive. When Glenn states they will need at least three people to save him, Eugene offers to stay behind and look after Tara.

With the others gone, Eugene uses this opportunity to escape, although he manages to carry Tara out of the building and take down two walkers in the process. He ultimately winds up helping the group by using noise from the van to draw walkers away from them. Afterwards, Eugene waits in the vehicle for rest of the group, when he is confronted by Nicholas, who orders him to drive off now or he will be left behind. Eugene refuses to leave without the others, but is unable to stop Nicholas from commandeering the van. Nevertheless, Nicholas is stopped by Glenn, who savagely beats him. On the drive back to Alexandria, Eugene is seen staring at the still-unconscious Tara.

"Conquer"
Eugene appears sleeping by Tara as Abraham comes by to check on her. Abraham then notices Eugene sleeping and says that he'll be back to check on her later after he left, but before he can leave Rosita knocks over a nearby pan sleet on purpose to wake Eugene. After giving her a shocked and disapproving stare, Abraham turns back towards the now awake Eugene. The two begin a slow conversation, with Eugene mentioning that Tara saved his life multiple times before he did the same. He then goes on to apologize to Abraham for lying to him about Washington. After a brief moment Abraham does the same, mentioning that he almost killed Eugene. After the two make amends they continue to watch over Tara with Rosita.

Eugene is later present at Deanna's community meeting, regarding Rick, and witnesses everything that takes place.

"First Time Again"
Eugene is first seen at Alexandria's infirmary where he visits Tara. A few seconds later, Glenn and Nicholas enter, wounded from their fight with each other in the woods but tell the people inside it was an accident relating to shrapnel. Eugene is later seen at one of the gates when an unknown man, who introduces himself as Heath, comes up, asking for entry. Eugene tells him that he is simply covering for another's shift and is unable to let him in due to lacking the proper authority. However, he eventually lets him in after Heath tells him that he lives in Alexandria. Heath asks him if any recent events had taken place, and Eugene tells him to speak with Deanna. Before he leaves, Eugene tells him that he appreciates him keeping up with the "hair game".

He is later seen at the meeting discussing about Rick's plan relating to the large herd at the nearby quarry. Sometime after, he is seen in the food pantry gathering food for himself when he overhears one Alexandrian, Carter, trying to convince Deanna's son Spencer, Tobin, Francine, and Olivia to help kill Rick and take back Alexandria from Rick as he believes they are becoming dangerous and power-hungry. Eugene drops a glass jar which alerts Carter of his presences. Carter approaches Eugene and says that he heard the plan before aiming his gun at Eugene. Eugene states that he didn't hear anything. He is almost killed by Carter, but is saved as Rick, Michonne, and newcomer Morgan Jones walk in on them and disarm Carter.

"JSS"
Eugene and Tara head into the infirmary and meet Dr. Denise Cloyd who was a psychiatrist. She had wanted to help out Pete, the previous town doctor, but he didn't want her help. Now with Pete's death she is the Safe-Zone's new doctor. Eugene is not sure of of her but Denise asserts she can do it. Meanwhile during the Wolves attack, Aaron and Rosita bring Holly in after she got attacked. Eugene stays with Denise and Tara. When they were trying to help Holly, Eugene doesn't want Denise to be a coward. When Denise tries to preform surgery, Holly dies.

"Now"
Eugene is briefly seen listening to Rick's speech to the Alexandrian's regarding the herd outside the walls.

"Always Accountable"
At the end of the episode, Eugene's voice is heard calling for help on the radio.

"Heads Up"
Eugene is seen attending Rosita's lesson on how to use a machete, but seems very distracted by the noise of the walkers outside. He admits that he's scared of dying; Rosita tells him that dying is easy and that watching friends die is much harder to bear.

"Start to Finish"
Eugene is rescued by Tara and Rosita from the herd of walkers, seconds after hearing Daryl on the radio and letting out a cry of help. The three seek refuge and get trapped in a nearby garage. Later, Eugene uses his lock-picking skills to escape the room. They stumble into the same room where Owen is holding Denise captive, with Carol and Morgan unconscious on the floor. He forces them to surrender their weapons and Eugene watches as the Wolf leaves the house, taking Denise with him.

"No Way Out"
During the final battle in Alexandria, Eugene informs Rosita that they will soon have to make a stand against the herd, but she tells him that "we will, not you", knowing he is unlikely to do anything. When Morgan, Carol, Tara and Rosita go out into battle, Eugene decides to join them, even after Rosita says he doesn't have to - he tells her "no one gets to clock out today. And hell, this is a story people are gonna tell." Eugene then proceeds to fight in the battle and helps to slaughter the herd throughout the night. The next day, he is seen with the other residents resting at the infirmary.

"The Next World"
Eugene opens the Alexandria gates for Rick and Daryl as they leave for a supply run. He gives Daryl a map of the area and discusses ways to track down sorghum in order to drastically improve their food stocks.

"Not Tomorrow Yet"
Eugene attends the meeting at the church concerning the plan of attack on the Saviors. He is later seen shortly after Rosita and Abraham break up, standing at their bedroom doorway while eating one of Carol's beet and acorn cookies and commenting on the cookie's soft texture, before Rosita slams the door in his face.

"Twice as Far"
Eugene is first seen taking over his daily shift on gate duty.

Eugene and Abraham leave Alexandria. Abraham comments on Eugene’s hair and his recent transformation. Eugene tells him he is a survivor, which Abraham dismisses.

They arrive at a building that Eugene plans to use for manufacturing bullets. Abraham is about to kill an approaching walker, but Eugene calls dibs. The strike from his machete bounces off the metal that has melted on to the walker’s head and he struggles with it, Abraham eventually stepping in and killing it. Eugene is furious and tells Abraham he no longer needs his protection and has outlived his usefulness to him. Abraham leaves and tells Eugene to find his own way home.

After Denise is killed by Dwight, it is revealed that he and his men have captured Eugene. Dwight demands that he, Daryl and Rosita take them back to Alexandria and if they do not oblige, he will kill them. Eugene spots Abraham hiding behind oil barrels nearby and insists that they should kill him first. Dwight orders one of his men to investigate, and while he is distracted Eugene turns and bites his crotch. Abraham uses the distraction to shoot two Saviors, and Daryl and Rosita are able to retrieve their guns. Dwight manages to break free from Eugene, who is hit during the shootout. As Dwight and the remaining Saviors flee, Abraham, Rosita and Daryl carry Eugene back to Alexandria.

Back at the infirmary, Eugene has been patched up after he was grazed by a bullet. He tells Abraham that he was not trying to get him killed and was looking for their opportunity. Eugene asks him if he is apologizing for doubting his skills as a survivor. “You know how to bite a dick, Eugene, and I mean that with the utmost respect,” Abraham says.

"Last Day on Earth"
Eugene insists on joining Rick and the others in escorting Maggie to Hilltop in the RV. When the group encounters the first blockade of Saviors, Eugene exits the vehicle with everyone else while Rick converses with one of the Saviors. Once back inside the RV, he and Sasha study a map and figure out an alternative route.

The group come across a line of walkers chained together blocking the road. Eugene notes that such an elaborate roadblock took a lot of people to accomplish. When the Saviors start firing at them from the woods, Eugene retreats back into the RV as Rick clears a path for them to continue.

They encounter yet another roadblock, this time a giant wall of logs in the middle of the road. Eugene points out the tire marks and again comments that this took vast manpower and a lot of vehicles. The Saviors then hang their captive from a nearby overpass. The logs erupt in flames behind them, and the Savior remarks that it may be the last day on Earth for one of Rick’s people. They return to the RV and drive off.

Inside the RV, Eugene points out that the Saviors are probably looking for the RV and might not expect them to travel by foot. After nightfall, Rick and Eugene go over the plan: Eugene will drive the empty RV to lure the Saviors. Eugene hands Rick a recipe for making bullets, in the event that he gets killed. Rick smiles and says that they're lucky to have Eugene with them. "You're a survivor," Abraham tells Eugene. They hug. Eugene then gets into the RV and drives away.

It is revealed Eugene was captured and beaten by the Saviors, and he is lined up with the others. Negan then exits the RV and tells the group that he is going to ‘beat the holy hell’ out of one of them as punishment for killing his men. He begins his game of Eeny, Meeny, Miny, Moe and as his bat crashes down on one of the survivors, Eugene’s fate is left unknown.

"The Day Will Come When You Won't Be"
When Abraham is beating beaten by Lucille, Eugene can be seen visibly scared, and on the brink of tears after seeing his friend die. When Negan begins to bash Glenn's skull in, Eugene is shocked, and can be seen crying. He will later help Rosita and Sasha carry Abraham's body to the RV.

"Service"
Eugene is by the gates as Rosita and Spencer drive up and ask him to open it. Spencer asks if he would like to help, but Eugene says he doesn’t think he’d be up to that and he is repairing a portable audio system for when the Saviors arrive. He looks worried when Negan shows up and demands to be let in. Later, he is present during the meeting in the church to locate the missing guns. When no one speaks up, he looks around and notes that some people are absent from the meeting. That night, Rosita pays Eugene a visit and shows him an empty shell casing and asks him to make her a bullet.

"Swear"
Eugene is on lookout duty when he sees Tara approaching Alexandria. He meets her at the gate and starts tearing up, upset about Tara finding out that Denise, Glenn and Abraham were killed by the Saviors.

"Sing Me a Song"
Eugene and Rosita are about to leave when he realizes she has no intention of scavenging for Negan. After arguing with Spencer, Rosita leads Eugene out of Alexandria.

Eugene and Rosita arrive at the factory that he had previously taken Abraham to with the intent to manufacture bullets. She orders him to make her one using the shell casing she found in Alexandria. Eugene hesitates and says that a single bullet won’t do it as the Saviors have the numbers and someone will pay the price for her actions. Rosita calls him a coward and says he is only alive because he lied and people feel sorry for him. She says she will pay the price and tells him to do something useful for once. Eugene quietly gets to work.

As they approach Alexandria, Rosita thanks Eugene for making a bullet and apologizes. He refuses to accept the apology and says that she meant what she said, now she just feels bad. Spencer drives up and reveals a bounty of supplies and weapons. He whistles towards the gate and a Savior opens it. They realize that Negan is in Alexandria.

"Hearts Still Beating"
Eugene watches as Laura flirts with Spencer. She calls him out before telling him to leave.

Eugene gathers round with the other residents as Spencer and Negan play pool in the street. He watches in horror as Negan disembowels Spencer, and Rosita tries to kill Negan with the bullet he reluctantly made for her, but she hits Lucille instead. Negan recognizes the bullet is homemade and demands to know who made it. Rosita insists it was her, and Eugene is horrified when Arat shoots Olivia in the face as punishment. Negan refuses to leave until he knows who made the bullet. Tara steps in and claims it was her, but Eugene interjects and confesses it was him. Rosita begs the Saviors to take her instead as Eugene is taken away.

Relationships
{{Scroll-1|

Abraham Ford
"Thank you for your protection... I almost certainly needed it between here and Houston but your services are no longer required. The truth, plain and honest. You've outlived your usefulness to me."

- Eugene scolding Abraham after saving him from a walker.

Abraham is seen to be Eugene's escort to Washington, DC. It is seen that Eugene feels a superiority complex over Abraham, because he considers himself to be smarter than Abraham. However, Abraham does not appear to be that angry over the disabling of their vehicle, despite it being caused by Eugene's poor riflemanship from his failed attempt to kill some walkers. Abraham was willing to do anything to protect Eugene, up until the latter finally revealed that he is not a scientist and doesn't know how to stop the plague, completely severing their friendship and partnership, as Abraham beats Eugene almost to death. Despite this, Abraham still preserves Eugene's life when he knocks a bottle of water he found on the road from his hand, fearing it could be poisoned. Their friendship is repaired while visiting an unconscious Tara- Eugene apologizes for his lie as Abraham apologizes for almost killing him, and they both seem to return to being friends. However, in "Twice as Far" when Abraham saves him from being bitten by a walker whose head is drenched in liquid metal, Eugene scolds him as he could have killed it himself and that he no longer needs Abraham's protection but the two repair their relationship after Eugene helps save Rosita and Daryl from the Saviors by creating a diversion and biting Dwight in the crotch, taking a bullet during the firefight as well. When Eugene volunteers himself as a diversion to get Maggie to Hilltop, Abraham and he share a touching moment of reminiscence, and they hug. Upon Abraham's execution, Eugene is utterly devastated by the loss of his mentor, protector, and best friend. Eugene will later help carry his body to the RV.

Rosita Espinosa
As traveling companions, it can be assumed that they have a stable friendship. However, in "Us", Rosita is annoyed at Eugene's lack of navigational skills. Eugene is also mentioned by Abraham to be attracted to Rosita, as he watches her and Abraham together quite often. After finding out Eugene is a liar, Rosita stood up for him, protecting him from Abraham's wrath, proving that she does see him as a friend. She also works to reconcile Abraham and Eugene's relationship, showing a level of compassion.

As the two continued to survive the apocalypse alongside each other, Rosita began to look down on Eugene, doubting his capabilities due to his awkward and cowardly nature; this was especially evident during the machete lessons she had been conducting with the Alexandria residents in "Heads Up", where she lectured him on fear, and in "No Way Out", where she decided that Eugene was not capable of fighting. He soon proved to her that he was indeed a capable fighter during the herd massacre. It is assumed that she now treats Eugene with more respect as a survivor.

Tara Chambler
"Thank God nothing happened to your hair.''"

- Tara to Eugene

Eugene has a very close relationship with Tara. Upon meeting and traveling with Tara, Eugene is shown to take an interest in Tara in "Us" where he talks to her about video games. Later when Abraham decides to let Tara and Glenn go through the tunnels alone, Eugene confesses to Tara he finds her "seriously hot", she tells him that she's a lesbian and he claims he already knew, although it is unclear if he was being truthful. Later, 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. Eugene and Tara interact several times throughout the journey to Terminus, Gabriel's Church and the road to Washington. Eugene confides in Tara that he was the one to disable the bus carrying them to Washington, and despite her best judgement, Tara keeps his secret. Tara does appear stunned to learn Eugene lied but is actually more sympathetic towards him than the others, as he had little survival skills and lying was the best he could do.

During their time at Alexandria, Eugene goes on a run with Glenn, Tara, Noah, with two Alexandria residents to find a device that would restore power to Alexandria. Tara is severely injured in an explosion, and due to his new found friendship with Tara, Eugene has a change of demeanor. He vowed to Glenn that he'd keep Tara safe, and surrounded by walkers, Eugene picks Tara up and exits the warehouse in which they'd entered to find the device; killing walkers as he brings her to the van outside. He has also been shown to visit Tara several times while under medical care. When he seen Tara awake in "First Time Again", he was shocked with happiness.

Glenn Rhee
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 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. Eugene later accompanies Glenn on a supply run after arriving at Alexandria and they appear to be on good terms now. Eugene was horrified and reduced to a sobbing wreck that he covered his eyes when Negan killed Glenn.

Sasha Williams
When they first met, Sasha appeared to be stunned to hear that Eugene knew what caused the outbreak and agreed to accompany him and Abraham to Washington. However, Sasha still appeared skeptical as she demanded he tell her what the cure was and how it worked. Eugene did, but nevertheless Sasha still protected Eugene from the walkers in their escape from Terminus. It is unknown how Sasha reacted to Eugene's lie, but she seems to be on neutral ground with him regardless.

Rick Grimes
Eugene and Rick have a good relationship. Though they haven't interacted much, Eugene seems to respect Rick's abilities as a leader, trusting Rick's plan to kill Gareth and the Hunters despite the plan involving using himself as bait. He was also present when Rick announced his desire to find Noah's home community in Richmond, Virginia, and when they arrived in Alexandria followed, through with his plan to stay in one house rather than be divided among themselves in case Alexandria was more than it appeared. In "First Time Again", Rick saved Eugene from being killed by Carter.

Maggie Greene
In "Self Help", Maggie, along with Tara, is supportive of Eugene and his abilities and a friendship develops between them. Despite having lied, Maggie still tried her best to revive him after getting knocked out by Abraham, despite clearly being mad at him. Maggie and Eugene are on better terms now as they have been seen together without any resentment present towards him.

Aiden Monroe
When Glenn, Tara, Noah, Nicholas and Aiden returned from their first supply run together Eugene saw Glenn and Aiden coming to blows and appeared concerned for Glenn and witnessed them fight. Eugene later, reluctantly, accompanied them on a supply run to find more parts for Alexandria's generator. Though Eugene tried to plead his case not to go Aiden still insisted he needed to as he didn't want to "come back with the wrong shit". When Aiden accidentally causes and explosion that gets impaled through metal bars but still alive, Eugene insisted Glenn, Noah and Nicholas rescue him. How Eugene reacts to Aiden's death is unknown but he was presumably saddened.

Nicholas
Eugene and Nicholas didn't interact much but they didn't get along well due to Nicholas' cowardly nature. Later when Eugene rescues Tara but Nicholas arrives without Glenn or Noah Eugene immediately stopped him from taking off in the truck, demanding to know where his friends are. When Nicholas threatened to leave him if he didn't get back in the truck, Eugene immediately pulled out his gun to shoot him though Nicholas overpowered him but Glenn arrived in time to stop him. Eugene may have lost any respect for Nicholas after this as he was seen holding him at gunpoint while unconscious on the trip back.

Noah
Though they didn't interact much, Eugene appeared to care for Noah's well being. Eugene accompanied Noah on a supply run and was greatly saddened to learn of his demise.

Carter
Eugene and Carter didn't interact much but they have a bad relationship, especially after Carter tried to kill him after overhearing his plot against Rick.

Trivia

 * The name used for Eugene's casting call was "Wayne Kesey", until the casting was revealed at NYCC on October 12th, 2013.
 * In an interview with Access Hollywood, Josh McDermitt described Eugene as someone who lived "in a dark apartment, by himself, maybe with his mom, and not so much a hoarder of everything, but just a hoarder of just like weird items that mean something to him that would mean absolutely nothing to someone else."
 * Eugene is one of the seven main characters to never kill another human being on-screen, including Lori, Andrea, Dale, Hershel, Gareth, and Deanna. However, Deanna and Gareth have ordered the execution of another character.
 * Eugene is the only of these seven to still be alive.
