- "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[src]
Eugene Porter is a main character, 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 the Saviors, but were not recognized by the members of Alexandria. He is good friends with Abraham and Tara Chambler. He later joined The Saviors.
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. 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. 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. However he still agrees to the label of coward, showing that he still finds it hard to be courageous.
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 he admits it's highly unlikely but he finds the theory highly 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. 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.
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.
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.
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..
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 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 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.
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 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 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.
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 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 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. After the brief fight that follows, Eugene watches as Negan prepares to murder Carl before they are attacked by the residents of the Kingdom and the Hilltop, forcing Negan and his surviving men, including Eugene, to retreat.
Returning to the Sanctuary, the Saviors prepare for war, Eugene amongst them. Negan questions Eugene on Sasha's death, but he lies that they wrapped the tarp too tight around the coffin and she suffocated.
Eugene will appear in this Season.

- 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 has been captured four times, and is tied with Glenn and Daryl for being captured the most amount of times.
- He has been captured by Gareth at Terminus in Season 4. In Season 6, he was captured twice by the Saviors: once was by Dwight after he and Abraham parted ways and the other was from trying to set up a diversion at the road blocks which failed and led to him being captured and added into the lineup to meet Negan. He was captured again in the mid-season finale of Season 7 after revealing that he was the one that made Rosita a bullet to try and assassinate Negan.
- Talking with Access Hollywood, executive producer Gale Anne Hurd revealed that she believed Eugene to have Asperger's Syndrome.
- Josh McDermitt refused to officially confirm the claim, but suggested its validity, saying "I don't want to address that. That's something for me, whether he has it or not."
- As of The Day Will Come When You Won't Be, Eugene, Rosita and Tara are the only remaining main characters introduced in Season 4.
