- "I was scared as hell you didn't make it. Truly. The entirety of every second of every minute I was out there. I'm torn to tethers about Jesus, but if anything had happened to you (...) I keep thinking that. That in a quick twist, it could've been me instead of him at the end of that blade. We all wait and wait for the right moment to say what's nearest and dearest, and before we know it, the sand has passed through the hourglass. Which is all my way of saying that I'm done waiting. I'm done playing the losing game of "wondering whens." I truly..."
- —Eugene trying to confess his feeling to Rosita.[src]
Eugene Porter is a main character and a former antagonist as well as a survivor of the outbreak in AMC's The Walking Dead. He and his travelling 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 Negan, but were not recognized by the members of Alexandria. He later joined the Saviors and eventually became a high-ranking member, serving as one of Negan's lieutenants and the Sanctuary's chief engineer. Following a tense encounter with his former protector Rosita, Eugene reevaluated his decisions and saved the Militia by causing the Savior weapons to explode at a vital moment, earning his friends forgiveness and acceptance once more. Six years after Rick Grimes' assumed death, Eugene now serves as Alexandria's engineer, with people having a greater appreciation for his talents.
Eugene is aloof, eccentric, 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 also extremely able to force locks. Due to some of his personality quirks, Eugene may have Asperger's Syndrome, a fact that producers have hinted at. He shows extremely poor social skills, poor coordination, peculiar habits of speech, and seems to have difficulty reading body language. He enjoys reading books and he is shown to be highly interested in video games. He sports a mullet, which he is very proud of. He is somewhat of a voyeur, who enjoys watching people having sex and eyeing up women. He very rarely smiles and speaks in a long winded, pedantic and clinical fashion. He has on occasion shown an ability in neologisms, evident when he saw a very unusual stuffed toy he took a liking to and named it a "grimbly gunk". He has a fondness for good food such as lobster, and also enjoys pickles.
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, although at the same time he was genuinely remorseful over this-he was always compassionate enough to care when others died and honestly showed regret over their sacrifices, but at the same time could not find the courage to put others before himself, something he was deeply ashamed of. After being kidnapped by the Saviors, he uses the same lie in order to impress Negan, and seemingly becomes one of his men in order to survive. 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, first when he saves Tara's life after being injured by a grenade. 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. Eugene even offers to put his life in danger to distract the Saviors from Rick and the group while they attempted to take a sick Maggie to the Hilltop Colony, showing how mature he'd become over the course of the series.
Eugene's newfound confidence, courage and selflessness however is severely retracted when he is captured along with his fellow survivors by the Saviors and is forced to witness the brutal executions of his close friends Abraham and Glenn within minutes of each other. Ever since that night, Eugene has reverted back to his cowardly state in order to continue surviving under Negan so he can never feel as afraid for his life as he did at that moment.
As the Sanctuary comes under siege, Eugene is shown to heavily question his decisions and his loyalties. As a result, Eugene has trouble sleeping and begins drinking heavily. Though Eugene discovers that Dwight has betrayed the Saviors, he chooses not to expose him, even after Dwight directly foils his plan to lead the walkers away. He is also conflicted with whether or not to help Gabriel escape with Harlan Carson to help Maggie and claims that Rick's group are now just his former traveling companions. Daryl and Tara leading the walker herd inside the Sanctuary appears to cause Eugene to let go of all ties to his former friends and to now state that anything he does will be for his own benefit. Despite this, Eugene still remains conflicted to the point that he aids Gabriel and Harlan in escaping to ease his conscience.
After being made the leader of his own outpost, Eugene begins to act more tyrannical and cruel, appearing to let his new power go to his head. He shows little care for Gabriel beyond keeping him from getting others sick (although this is most likely because he is angry about the death of Harlan, who was killed after Gabriel convinced Eugene to help them escape from the Sanctuary).
After an encounter with Rosita and the reminder of his betrayal of the only friends he ever had, Eugene has a change of heart and takes a stand by sabotaging the Savior weapons to allow the Militia to win. In doing so, Eugene acts selflessly as he would've been safe if he hadn't betrayed the Saviors and allowed them to slaughter his former friends. Eugene's act of bravery saves the lives of many people and earns him the forgiveness of the friends he had proclaimed to no longer care about. When discussing his choice with Rosita, Eugene makes it clear that it was her opinion of him and his actions that swayed him to do the right thing in the end.
Six years after Rick's supposed death, Eugene seems to have become a far braver, more competent, and more selfless individual, as he fearlessly took out several walkers, was willing to distract a large herd so that Rosita could get away, and encouraged Gabriel to stay with Rosita after she became pregnant with Siddiq's baby, despite his own feelings for her.
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 and once stated the zombie disease could have caused the extinction of the dinosaurs (though he admits it's highly unlikely but he finds the theory amusing). 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.
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. During their journey they encountered fellow survivor Althea, who interviewed them both before parting ways.
Eventually, they were joined by Rosita Espinosa and several other survivors, who traveled from Houston to northern Georgia, losing several members on the way.
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.
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.
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.
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.
Michonne 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.
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, D.C. with them during dinner. Rick agrees.
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 and kills Gareth and the Hunters. The next day, Rosita, Abraham, Eugene, Maggie, Tara, and Glenn head to Washington, D.C.
Eugene is first seen in the bus thinking about what Gabriel had been saying at the church. Tara tells Eugene that his hair is getting a little long in the back, and suggests he gets it cut. Then, she jokes, "Or is it your source of power?" Eugene responds, "I ain't slaying a lion anytime soon, and I wouldn't be putting any wagers on me dispatching 1,000 philistines with the jawbone of an ass." Tara asks Eugene what’s up, and he says he's thinking about what that preacher did.
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 he 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 up behind Eugene, and Eugene admits to watching Abraham and Rosita. Eugene says he enjoys the female form, and he considers it to be a victim-less crime which provides a distraction. Tara says that she was looking for Eugene to thank him for saving her life back at the bus. Eugene reveals that he sabotaged the bus to make it crash. Eugene says he put crushed glass in the fuel line back at the church and that the vehicle should have failed before it even got to the road. When Tara asks why he did that, Eugene says that he couldn't survive on his own. Eugene says that if he couldn't save the world that there is no way they would keep him around. Tara says they would because they're friends. Tara says that Eugene needs to keep secret what he did and not to do it again. Eugene goes, at Tara's urging and she takes a swift look at Rosita and Abraham before she goes as well.
The next day when the group is attacked, Eugene uses a fire hose on top of a fire truck to save everyone. The group continues 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 it's 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 reveals that he lied about knowing a cure, and that he only wanted to get to Washington, D.C. in order to ensure his survival Rosita guilts him by telling him people died trying to get him here, including Bob. Eugene admits he is aware of that, but when he inadvertently comments that he is "smarter than you" an enraged Abraham punches Eugene repeatedly, badly injuring him and leaving him an unconscious bloody mess.
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.
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.
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.
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.
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.
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.
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. Eugene asks Glenn to know what happened to Noah, but Glenn refused to answer as they put Nicholas in the back of the van. On the drive back to Alexandria, Eugene is seen staring at the still-unconscious Tara.
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.
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 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.
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.
Eugene is briefly seen listening to Rick's speech to the Alexandrian's regarding the herd outside the walls.
At the end of the episode, Eugene's voice is heard calling for help on the radio.
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. Eugene walks away while Rosita continues on with her lesson.
Eugene is later seen when Spencer shimmies over the wall along a rope he's attached to the watchtower with a grappling hook.Eugene and Tara notice that the rope is slackening, and Eugene goes to get help. As the grappling hook loses its grip, Spencer falls into the herd. Tara hangs off the wall, and begins shooting at walkers so he has a chance to escape. Soon after, Rick, Tobin and Morgan manage to pull Spencer up to safety.
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.
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.
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.
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.
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 Neil to investigate, and while he is distracted, Eugene turns and bites his crotch. Abraham uses the distraction to shoot two Saviors, including Neil, 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, which he confirmed. "You know how to bite a dick, Eugene, and I mean that with the utmost respect," Abraham says in awe.
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 comes 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.
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 kill Glenn's in the same manner, Eugene is horrified, and can be seen sobbing into his hands. He later helped Rosita and Sasha carry Abraham's body to the RV.
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.
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.
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, deeply hurt and wounded by her words.
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.
As Spencer hands over his scavenged goods to the Saviors, Laura begins flirting with Spencer, in which Eugene watches from a short distance away. Laura catches him and orders him to walk away or else.
Later, Eugene gathers around 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 lies and 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.
Eugene arrives at The Sanctuary and shakes with fear as he is escorted through the building by Laura, who takes him to a private apartment and reveals Daryl has escaped. She asks Eugene if he has any leads to his whereabouts; Eugene tells her that he doesn't and assures her that he'd tell her if he did. Eugene is delighted to find the fridge stocked with food and Laura offers him something to eat. He asks for canned pasta in tomato sauce. He's disappointed to learn that they're out of pickles.
Laura shows Eugene around the factory floor and explains the Saviors' point system, which he's exempt from; he can take whatever he wants. She gifts him a jar of pickles. Outside, Eugene is brought before Negan. When asked for his name, Eugene responds with "Eugene." Negan then prompts the Saviors for their names and they respond in unison: "Negan." Negan grills Eugene about his credentials. Scared, Eugene falls back on an old lie and claims he has multiple PhDs and was part of the Human Genome Project. Negan asks Eugene for advice on how to prevent his fence-line walkers from deteriorating. Eugene impresses Negan with his proposed solution: covering them in a shell of liquefied metal that will make the walkers indestructible once it dries. As a reward for his ingenuity, Negan offers to send several of his wives to Eugene's apartment.
Eugene plays video games while three of Negan's wives watch. During conversation, Tanya jokingly asks if Eugene knows how to make a bomb. Eugene lists the ingredients he would need to make one.
Later, Tanya and Frankie visit Eugene, seeking his help; they explain that Amber wants to commit suicide and ask if he can make some pills for her. Eugene reluctantly agrees. He uses his position of power to cut in line in the marketplace and order cold capsules. He goes back to his apartment and makes the pills.
Laura escorts Eugene to the factory floor, where a crowd has gathered around the furnace. Negan enters and points Lucille directly at Eugene. "You are gonna wanna pay close attention to this," he says. Eugene tries to look away as Negan beats Dr Carson, but Laura forces him to watch as Negan throws Dr Carson head first into the furnace, burning him alive, and horrifying Eugene further.
Frankie and Tanya visit Eugene in his apartment. He correctly guesses that the pills are for Negan, not Amber, and refuses to hand them over. Tanya calls him a coward, to which Eugene responds "That's a correct assessment" They leave angrily.
Negan pays Eugene a visit. He tells Eugene that he doesn't make his invitation lightly and explains that he doesn't need to be scared anymore. Negan asks Eugene "Who are –" but before he finishes the question, Eugene seemingly betrays his former friends by responding "I'm Negan".
Eugene oversees workers at the Sanctuary fence-line as they execute his plan to fortify the walkers with molten metal. Dwight joins Eugene on the upper stairway. Dwight asks him if he's on board; Eugene assures him that he is. After a name exchange, Eugene ends his introduction with, "We are Negan." To this, Dwight reluctantly replies "...yeah."
While trying to assassinate Negan, Rosita and Sasha observe Eugene in the Savior's compound, apparently giving orders. They later hear a radio broadcast made by Eugene who is now the Saviors Chief Engineer. That night, while Eugene and another Savior go to examine the fence, Rosita and Sasha kill the other Savior and attempt to rescue Eugene. Tearfully, Eugene refuses, telling them that he didn't ask to be rescued nor does he want to be. Eugene tells the two to go as other Saviors must be en route before running back inside.
Eugene brings Sasha a blanket and pillow. He explains that he's never been as scared as he was that night in the RV in the woods; he joined Negan to ensure he never feels that way again. He recommends she do the same. Sasha orders him to leave.
Eugene stops by Sasha's cell and assures her she made the right choice in joining Negan. Sasha sobs, convinced that she made the wrong decision and she'll be used as a tool against Rick's group. She begs Eugene to bring her a weapon – a knife, gun or razor blade – so she can kill herself before Negan uses her against their friends. He agrees to consider her request.
Eugene knocks on Sasha's cell door and slips her the suicide pill that he made for Frankie and Tanya. He tells her he does not want her to go, but by the sounds of things she's already gone.
After arriving at Alexandria, Eugene calls for Rick to concede or die. Rick reluctantly signals Rosita to trigger the explosives in the moving van next to Eugene, but the Scavengers have betrayed Alexandria and Rick's group is captured. As Negan releases Sasha from the coffin, she emerges as a walker, having used Eugene's suicide pills. A firefight immediately breaks out, and Eugene flees back to the truck. He is later transported out of Alexandria when reinforcements from the Kingdom and the Hilltop force the Saviors and Scavengers to retreat.
Returning to the Sanctuary, the Saviors prepare for war. Negan questions Eugene on Sasha's death, but he lies that they wrapped the tarp too tight around the coffin and she suffocated.
Eugene makes his first appearance during the Militia's attack on the Sanctuary. He exits the Sanctuary alongside Negan, Dwight, Simon, Regina and Gavin. Eugene tries to talk but Rick shuts him down. Rick offers everyone a chance to survive if they surrender.
Eugene and the others refuse to surrender, and once the Militia opens fire on them, he and the others proceed to flee back inside the Sanctuary.
Eugene is present for the meeting with Gregory, Negan and his other lieutenants (Simon, Dwight, Regina, and Gavin) at the Sanctuary. They discuss the joint rebellion of Alexandria, the Hilltop and the Kingdom. The meeting is interrupted when shots are fired by the militia, and Regina and the others exit to face the intruders. The events of "Mercy" then take place.
Following the herd and the loss of Negan, the lieutenants inside the Sanctuary debate what to do in their current predicament. Regina is the first to suggest that they must assume Negan is dead. Simon disagrees and questions if Regina is really Negan; she states that she is. She then proposes that they send a crew of forty workers outside to clear a path in the herd, but Eugene argues that the workers would be overcome in minutes. Regina explains that the workers would be a distraction while a small team snuck past the herd to warn the outposts. Eugene points out flaws in that plan as well, claiming it would cause unrest among the workers. They continue to disagree until Dwight becomes a voice of reason. Dwight takes Eugene's side. Gavin turns his attention to who the Savior mole has to be. Dwight turns the conversation to everyone needing to get out. Simon agrees with Dwight and promises they will kill whoever the mole is, slowly over a few days, with everyone looking at Eugene.
Eugene enters Dwight's room with his jar of cucumbers. He expresses thanks for Dwight's support in the meeting. He tells Dwight they will get out of this "pickle" together. Eugene sits at a chess set and touches a piece but Dwight tells him to be careful and wait because they're still wet. he made them himself. Eugene leaves, thanking Dwight once gain. Eugene plays video games at the Sanctuary until the power suddenly goes out.
Later, Simon makes a decision to turn off Sanctuary's power since they cannot access the fuel reserves. The workers, suffering from the heat, move up onto the second floor, against their normal orders, knowing something is wrong and they demand to see Negan. Eugene and the lieutenants try to vouch for him when suddenly they hear Negan's whistling, and they all fall onto their knees. Negan and Gabriel, who escaped the trailer by covering themselves in the viscera of the walkers, have made it safely here. Negan reaffirms his power, and the workers quickly agree to return to work. Negan orders Gabriel to be kept in a cell.
Later, Eugene, his fellow lieutenants and Negan are being debriefed on a weapons bag from worker who tried to assassinate Simon earlier. The group concludes that a worker from the sanctuary could not have acquired anything from the armory and deduces it must've been given to them by the traitor. Eugene observes the bag and sees a spot of paint on it, the same color as that on his finger from touching Dwight's chess set. Keeping the discovery to himself while he looks at Dwight. Privately, Negan tells Eugene he will reward him handsomely if he can figure out the mole within the Saviors. Eugene later goes to see Gabriel and finds him suffering, and calls for medical attention. Eugene orders him to Harlan Carson, but Gabriel insists they have to get to the doctor for Maggie.
Eugene sits in his room, attempting to brainstorm a list of facts he knows about the current situation. He then confronts Dwight in his room and makes it known that he is aware of his involvement in Rick's plan. He attempts to talk Dwight down from any further opposition in exchange for keeping his involvement a secret, but Dwight insists that, with all that is occurring, the Saviors are sure to face defeat. Eugene refuses to defy Negan and walks out, warning Dwight not to try anything else that would result in any harm to the Sanctuary's inhabitants. Eugene observes the front doors of the compound, still swarmed with walkers. He asks Laura how long the barricades will hold, she theorizes at least one or two days.
Eugene is called to the infirmary by Harlan Carson, who is tending to Gabriel's worsening condition. Carson speculates several infections, and that Gabriel does not have long before his situation grows dire. While he shows concern due to not having the right medicine, Eugene condemns Gabriel's actions as a member of Rick's militia, deeming it partially his fault for his current condition.
Carson leaves Eugene in charge of watching Gabriel while he ventures to the marketplace to search for the appropriate medicine. Gabriel awakens, asking if Eugene is willing to help him break Carson out of the compound. Eugene reminds him that the area is overrun and that he is someone who only looks out for himself. They share a talk about the principle of doing the "right thing", Eugene is adamant that doing the right thing for one could mean trouble for another, while Gabriel argues that doing the right thing requires faith in one's self and believing that God has a plan for everyone. When Eugene deems Gabriel's beliefs as absurd, he retorts that as a man of science, Eugene would have initially doubted the concept of walking corpses, showing that the unbelievable is still possible. With this concept, Gabriel expresses hope that Eugene will eventually know when to do the right thing when the time comes. Eugene ponders his words, looking down at the dry red paint on his thumb.
Eugene is visited in his room by Tanya, who inquires about a broken radio that Eugene was tasked with repairing a week prior. He explains that he was unable to complete the task due to the current situation, and expresses concern that Tanya does not seem troubled; she recounts that she's already felt trapped while serving under Negan. Tanya give Eugene one more day to fix her radio, but he asks for the second bottle of wine that she is holding before she leaves, explaining that it'll help him sleep. Tanya explains that she also has trouble sleeping, due to the stress of not being able to rid the Saviors of Negan and the unsuccessful attempt of enlisting Eugene's help with the task. She condemns his choices before handing him the bottle and leaving. Laura then walks in, informing Eugene that Negan sent for him.
Eugene meets with Negan in the conference room. Negan expresses an increasing worry for the safety of his community, while praising Eugene and his efforts in the compound. He shakes his hand, explaining that not many people receive the same privilege of mutual respect. Eugene accepts this, declaring that there is work that needs to be done before leaving the room.
Getting to work on the radio, Eugene extracts one of the speakers, inspecting it. Gaining a fresh idea, he searches one of the storage rooms for materials. He comes across the coffin used to transport Sasha, having vivid and disturbing flashbacks to her shocking reveal as a walker. He opens it, discovering her discarded iPod still resting at the foot of the coffin. On one of the Sanctuary's balconies, Eugene sets his new contraption, a makeshift drone fitted with a speaker and an iPod, on a ramp leading out and above the walker herd, in hopes that the herd will follow the blaring music when it goes airborne. He records an audio log of his observations, but as he prepares to activate it, he is called out to and held at gunpoint by Dwight.
Dwight orders Eugene to step away from the drone. Eugene relays his plan to Dwight, insisting that he'll be saving the lives of the Savior workers and soldiers, but Dwight argues that his actions will also lead to the deaths of Rick and his men, people who Eugene now considers former travelling companions. He informs him that the plan will save the lives of both the Saviors and the Militia, and that taking out Negan is the number one priority and goal. Eugene remains firm that Negan will prevail, causing Dwight to threaten him further. Despite the gun to his head, Eugene proceeds to activate the drone and pilot it over the herd. As Eugene flies the drone, Dwight turns his gun's aim towards it and fires several times, destroying it. Eugene looks down and sees Daryl's truck heading toward the building. Several Saviors perched at the window are fired upon by Tara, Morgan and the lookouts as Daryl crashes the truck into the Sanctuary, breaching the walls and allowing the herd to pour in.
Eugene arrives in time to witness the brunt of the assault. Shock and horror slowly turns to rage and fury as he observes the dead feasting on several innocent workers. Storming into the infirmary, a fuming Eugene angrily rejects Gabriel's philosophies, blaming his and Sasha's downfalls on their choices of doing the "right thing" and refusing to help with Carson's escape, instead choosing to remain faithful to Negan and ensuring that Carson stays within the walls of the compound for his own sake. Gabriel says nothing as he storms back out.
Eugene proposes an escape plan to Negan, who comments that it will take much of their ammunition. Eugene concurs Negan's statement, while affirming that he will be able to restock The Saviors' munitions supplies given he has access to the proper manufacturing equipment. As he is about to reveal a solution regarding another emergency, Regina and Dwight enters the room reporting that they have secured the stairways while the walkers are contained to the ground floor. Eugene stares intently at Dwight, then informs Negan that he intends to repair the intercom system, giving them an advantage in communications with the rest of the community. Negan is underwhelmed, to which Eugene responds that it is merely something of personal pride.
Eugene sits in his room, the sound of gunfire outside ringing in his ears. Stress overwhelms him, and he hobbles toward his wine bottle, taking a shot before taking several swigs from the bottle.
Eugene continues to be unable to sleep and drinks heavily. Finally, Eugene awakens Gabriel and Harlan, stating that he has decided to help them escape. Though Eugene acknowledges that Gabriel likely won't survive the trip to the Hilltop, he is willing to fulfill his old friend's wishes to ease his conscience and though he doesn't believe so, Gabriel insists that he Eugene is doing the right thing. Eugene uses a massive dose of laxative to disable the guard at the North Gate and prepares a vehicle for the two, the keys to which he "accidentally" drops as he leaves Gabriel's room. Though Gabriel promises that Eugene will be welcomed back if he comes with them, Eugene refuses and remains with the Saviors.
In the flashes at the end of the episode, Eugene is shown to still be unable to sleep.
Eugene is questioned by Negan, disappointed that Eugene's efforts have not completely alleviated the issues at hand and that his two captives have somehow escaped undetected, unaware that Eugene was responsible. Negan affirms to that once Carson and Gabriel are caught and brought back to the Sanctuary, he will find out about their escapades. A nervous Eugene inquires about the events that occurred at Alexandria, Negan questions his inquiry, asking if he cares despite Alexandria's actions against him since his defection.
Negan then places Eugene in charge of his own outpost, a small team in charge of crafting munitions for the Saviors. Eugene shows concern, as Negan claims to view people as a valuable resource. Negan explains that the bullets are a last resort, should Rick's group refuse to come to terms with the Saviors. After Negan explains Eugene's security detail, Eugene asks if there will be a wine supply, he confirms this.
Eugene works with his team on crafting bullets. Frankie approaches him with the intent of helping around the workshop. Eugene instead treats her poorly, seeing her as a form of maid service. Eugene orders some food for his men. He designates a room as the cafeteria. Negan suddenly bursts into the room, followed by two Saviors bringing in a recaptured Gabriel, but not Carson, who was killed by the Saviors.
Negan claims to have a story from Gabriel on the circumstances of his and Carson's escape. To Eugene's relief, Gabriel does not hold Eugene responsible for the planning of their escape, but rather Carson. Negan then leaves Gabriel in charge of arranging Eugene's bullet casings.
Eugene reports that while his munitions have been of great quality, the quantity of supplies is running low. He suggests the possibility of launching walker viscera at the opposing forces in a last-resort effort to dissuade them from fighting. Gaining a new set of ideas from this otherwise-ludicrous scenario, Negan leaves, satisfied. Eugene approaches Gabriel, who is still traumatized by Carson's death. He laments that he believed he had found his purpose. Eugene brushes this off and shoves a tray toward Gabriel, demanding he begin sorting casings.
Outside the Bullet Factory Outpost, Eugene is observed by Rosita and Daryl receiving a shipment of hundreds of bullet casings to make into new bullets. Rosita decides that instead of taking out the machines, they will take out the man, implying she intends to kill Eugene, something that Daryl agrees with.
At the Bullet Factory Outpost, Eugene chastises Gabriel for making faulty bullets because he doesn't want to see his friends killed and suspends him from the assembly line. Eugene is captured by Rosita and Daryl while heading outside to test the homemade bullets.
Eugene defends his loyalty to Negan, saying he did it to survive. but Rosita blames everyone's deaths on him for helping the Saviors escape the besieged Sanctuary. Eugene argues that Rick is the real cause of the war, which causes Rosita to angrily insult him, calling him a coward and traitor, and while they will let him live, he will be forced to work for them and lock him up. After seeing a herd of walkers, while Daryl fights them, Eugene forces himself to vomit on Rosita in order to escape. Eugene then hides under ashes as the pair pursue him.
Eugene returns to the Bullet Factory in a furious mood. Regina informs him that Negan is back and needs bullets by morning in order to spring a trap on Rick's group. Eugene orders everyone to finish in time so they can destroy them.
Eugene returns to the Sanctuary with his bullet order and gives a gun to Negan to demonstrate their effectiveness. Eugene learns that Dwight has been exposed as a traitor, but doesn't reveal his own knowledge of this fact. Instead, Eugene suggests that the Saviors use one massive firing line to overwhelm and kill the Militia at once, an idea that is accepted.
Eugene rides with Negan, Laura and Gabriel to Negan's ambush of the Militia, listening to Negan describe his plans in detail to Gabriel. When Gabriel tries to escape, Eugene chases after him with Laura and recaptures Gabriel. Holding Gabriel at gunpoint, Eugene berates Gabriel for his lack of faith before Negan interrupts.
During the Militia ambush, Eugene watches silently from beside Negan. When the Saviors open fire, their guns suddenly explode, killing many Saviors. Negan turns on Eugene in anger, but he is attacked by Gabriel and then Dwight, causing Negan to run. In the resulting battle, Regina and a few other Saviors go after Eugene who is unable to defend himself in time. However, Eugene's life is saved by Rosita who shoots down the Saviors. Following the surrender of the Saviors and the defeat of Negan, Eugene joins everyone else in listening to Rick's speech.
With the war over, Rosita asks if Eugene was responsible for the exploding Savior weapons. Eugene admits that he was, inspired by Gabriel's attempted sabotage and some of the things Rosita said to him while she held him captive. Rosita punches Eugene in the face for vomiting on her, but otherwise appears to forgive him.
During the year and a half that passed since the end of the war, Eugene moved to the Sanctuary to help Daryl and Rosita look after it's residents.
At the Sanctuary, Rosita helps Eugene with an experiment while Laura reports something to Daryl. Later, Eugene radios Tara while she is scouting to inform her that Daryl will be meeting the rest of the group so they can go to Washington, D.C. to search for farming materials.
When Rick and the group arrive at the Sanctuary to deliver supplies, Eugene tries to give Daryl a list of important materials they need but is told it isn't necessary the moment. Suddenly, Michonne points out graffiti that proclaims, "We are still Negan". Eugene tells Daryl that he doesn't know who painted that.
At a camp, which the communities have set up in the woods, Eugene talks to Rick about the deserted Saviors and a plan that will serve to distract an oncoming herd. When he notices a Savior with their hand missing, he stops and looks on in shock, feeling guilty. Later, when Rick arrives at the bridge to stop Daryl and Justin from fighting, Eugene helps controlling the Saviors. In the camp, at night, as everyone laughs and talks, Eugene is seen sharing a moment with Rosita, Tara and others.
At the camp, Eugene updates Rick on the status of the rising river in relation to their bridge construction. He apologizes for the bad news but Rick reminds him how valuable he is to them, making him smile.
On the bridge, as Rick limps away before collapsing, he hallucinates as Eugene and the others rush past him to kill the walkers. Michonne stops and sees Rick's wound. She reminds him she fell in love with him because he's a fighter. After killing the walkers, everyone stops to watch them. Michonne tells Rick how much she loves him and he tells her, "This isn't real." Michonne tells him to wake up and he does, now alone on the bridge.
The walkers approach as Rick hobbles away. He makes it across the bridge and turns around hoping to see the walkers fall through, to no avail. A walker makes its way inches away from Rick before getting shot in the head by a crossbow bolt. Rick watches as Eugene and the rest arrive nearby.
Maggie and Michonne hatch a plan to divert the walkers but Rick won't allow it. He notices the dynamite on the bridge, takes aim, and says to himself "I found them," before shooting and igniting the dynamite. The bridge ignites and explodes as Eugene and the rest can only watch in horror, assuming Rick to be dead.
Six years later, Eugene along with Rosita, Aaron and Laura find Judith in the woods helping Magna's group. A few walkers get close to the group and Eugene easily dispatches of them. Wanting to take them in, Judith declares she won't go return to Alexandria until they accept them. Eugene and the others reluctantly agree.
In Alexandria, Magna's group arrives at the gates and Judith assures them they'll be safe. They get escorted inside, where Gracie runs over to Aaron. Rosita updates Siddiq on Yumiko's condition and he escorts her to the infirmary. Magna tries to tag along but is stopped by D.J.
Michonne arrives on horseback and doesn't look pleased to see the new arrivals. She frisks Magna and asks Eugene why they're here. Aaron claims it was his call but Michonne reminds him it's not his call to make. "I decided," Judith tells her. Michonne scolds her but Aaron says they're here now and they should decide their fate together, while Gabriel suggests they vote tomorrow. Michonne agrees and instructs her people to put them in holding. She leaves as her sheriff figurine falls out of her pocket and Judith picks it up.
Later, on the way to set up the amplifier, Eugene questions Rosita about her fling with Gabe and reminds her some men prefer facts over fairy tales, implying he has feelings for her. Suddenly, they notice fresh footprints on the mud of a neary herd that head on a different direction, relieving them.
On top of a water tower, Eugene places the amplifier and begins to climb down before seeing a walker herd head toward them. Rosita screams for him to climb down as his pack falls and the horses get spooked. Part of the ladder falls so Eugene jumps down, injuring his knee. Rosita runs over with a makeshift crutch and the two run off into the woods.
In the woods, Eugene slows down as he and Rosita keep running from the walkers. He suggests he stay behind to distract them and reveals he has something to tell her. She tells him not to make it weird and forces him to keep going.
After a while, Eugene and Rosita slide down a ditch and cover themselves in mud as the walkers get closer. They stay still but get shocked and horrified as the walkers pass by and whisper to each other: "Where are they? ... They must be close... Don't let them get away."
At night, Daryl, Jesus and Aaron locate Eugene hiding in a barn cellar. A terrified Eugene warns them a herd of walkers is looking for him and they need to leave immediately. "This wasn't a normal herd... They were whispering to each other," he tells them. They look at him confused, when suddenly Dog barks, warning them of the nearby herd.
In the foggy woods, Eugene suggests to the group that the walkers are evolving. Daryl calls bullshit when Aaron notices they're drawing closer. Jesus demands they split up but Daryl says that instead, he will guide the herd away while he and Aaron take Eugene to the horses.
A while later, Eugene, Aaron and Jesus end up at a foggy cemetery. They quickly get trapped by a locked gate, forcing Aaron and Jesus to go kill the walkers, while they hear whispers around. Suddenly, Daryl, Michonne, Magna and Yumiko arrive to help them unlock the gate.
Jesus tells Aaron and Eugene to get out while he finishes the walkers and starts taking out several with his sword. He goes to kill the last one but as he attacks it, the walker dodges and stabs him from behind through his chest, shocking everyone. "You are where you do not belong", the walker whispers to a shocked Jesus before throwing him on the ground.
Daryl shoots it in the head as several more Whisperers arrive and the rest of the group run in to finish them off. As Aaron goes over to Jesus' body, Daryl notices something on the back of the walker's head and cuts into it, revealing a mask. Before they can process the situation, whispers around them get louder and the group circles up preparing for a fight.
In the cemetery, Eugene watches as the rest proceed to kill the Whisperers and walkers around them. When more arrive they're forced to carry Jesus' body away and lock the gates. As they leave, a whisperer opens the lock.
On the road, Eugene blames himself for Jesus' death, but Aaron claims it was his decision to go look for him. Suddenly, the group notices a small group of walkers nearby. Daryl corners them on a bridge and uses his crossbow to see who are whisperers. He hits one in the leg and the man falls down screaming in pain, attracting walkers to him. The rest try slowly escaping to the other side, where Michonne is waiting for them. They draw their knives and attack, but Michonne and the rest kill them with ease as the final Whisperer gets on her knees to surrender. Daryl rips off her mask, to reveal a girl begging for her life. Michonne angrily questions her but when more walkers show up, Daryl decides to take her with them.
Later, Eugene and the group arrive at Hilltop with Jesus' body and the captive girl, causing the whole community to react in disbelief.
In the infirmary, Siddiq relocates Eugene's knee and leaves to grab a bandage. Eugene tells Rosita he was scared she was dead and tries confessing his love, but she runs outside saying "I can't." Rosita vomits and Siddiq follows to ask if she's ok, but she reveals she's pregnant with his baby. Eugene looks horrified as he listens from inside.
A while later, a funeral is held for Jesus and everyone take turns hammering the nails in his coffin. Eugene looks in sadness and then proceeds to leave with the rest of the group to Alexandria.
In Alexandria, Eugene shows Gabriel his risk/reward calculations if he should stay with Rosita or not. Gabriel brushes it off, but Eugene warns him he'd be a fool to let her go. Eugene briefly reminisces on their time with the Saviors, and how Gabriel believed in him even when he himself didn't. He then offers him new sweatpants to give Rosita as a peace offering.
Later, as Gabriel visits Rosita to talk with her, Eugene watches and smiles, proud of his choice.
In a flashback, Eugene, Michonne, Gabriel, and Rosita follow Winnie to a factory where they find several kids hiding out. Later, at night, Eugene enjoys a bonfire in Alexandria alongside Jocelyn’s kid group and the community kids.
The next day, Eugene watches as Michonne and Daryl return to Alexandria with the missing kids. He inmediately orders the gates to be closed and goes over to help an injured Michonne.
In the Kingdom, Eugene watches from the crowd as Ezekiel declares they’ve finally accomplished Rick, Carl, and Jesus' dreams of reuniting the communities. “Let the fair of a new beginning begin!” Ezekiel says as everyone celebrates and applauds.
In the fair, Eugene plays with Judith and the kids in a dunk booth. Later on, he manages to trade some goods for some radio parts to make it easier for the communities to communicate with each other. He tries fixing it as Rosita arrives at his room and talks with him. She then tells him that despite her pregnancy, things don’t need to change between them and they are still friends. Later, Eugene walks around the fair asking for Frankie's whereabouts to Nabila and being asked by Gabriel to find Tara.
The next day, in the Kingdom, Eugene listens from the crowd as Siddiq delivers the tragic news, tells them how brave everyone was in their final moments and how he was intentionally kept alive to tell this very story. He encourages everyone to remember the fallen.
Several months after the fair massacre, at Alexandria, Eugene arrives at Gabriel and Rosita's house and interrupts them to report on the storm. Gabriel concocts a plan to group up next to large fireplaces in the church and realizes they’ll have free Negan from his cell so he doesn’t freeze.
In the church, Eugene is working on some things and listens in amusement as Negan jokes about Rosita's love quadrangle and taunts Gabriel by calling him “father…not the father”. Suddenly, the group smells something and Eugene pulls Siddiq and Gabriel away from the fireplace before it explodes. He says the chimney makes it unsafe to light anything else on fire, so Gabriel decides they’re moving to Aaron’s house. They all tie a rope around themselves and head out into the blizzard.
The next day, after the storm is over, Eugene moves back to his house.
