"I didn't know who I was talking to. I said I would do what I had to to earn my keep, but I didn't know you. But I know... I know who I am. I know what happened and what's going on. I know. You didn't show me shit. You, you're dead. Everything that you were is dead. And it's... it's not over. I forgave her because... it's not over. It's not over... It's-- it's not over. I didn't turn away. I kept listening to the news so I could do what I could to help! I'm not giving up. You hear me? I'm not giving up! People like me... people like me, they can live. Ain't nobody got to die today."
Tyreese Williams, nicknamed Ty by many of his companions, is a main character and a survivor of the outbreak in AMC's The Walking Dead. He is the older brother of Sasha and was also the leader of a small group of survivors. He became one of the first newcomers at the prison. During his time at the prison, he formed a relationship with fellow Woodbury survivor, Karen. After Karen's death and the downfall of the prison, he became the primary caretaker of Judith Grimes and also Lizzie and Mika Samuels temporarily.
A strong, yet compassionate, protective and unselfish individual, Tyreese struggles with his own morality while still managing to protect his group, often trying to prevent any bloodshed. He is shown to be wise, reasonable and thoughtful.
Very little is known about Tyreese's life before or as the outbreak began besides that he had a younger sister named Sasha and an anarchist neighbor named Jerry. He lived somewhere in Jacksonville, Florida. According to actor Chad Coleman on Talking Dead, Tyreese was a former NFL player.
As the outbreak began, he and his younger sister Sasha stayed in a bunker in their neighbor Jerry's backyard for about 7 months until they ran out of supplies. After that, they met up with Allen, Donna, and Ben and joined a larger group, which had about 25 survivors at one point. The camp was eventually overrun, and many were killed. For about six weeks they wandered until they arrived at the West Georgia Correctional Facility. During this time Tyreese saved Donna and she became somewhat smitten with him.
Tyreese makes his debut appearance in this episode. He is seen with a group of survivors in the woods. One survivor from his group, Donna, is bitten on the arm by a walker, while escaping from a small herd. While they run away, Tyreese discovers a destroyed wall, which ends up being the back of the prison. Tyreese leads them through the broken part of the fence and into the facility. Tyreese's group is attacked by walkers again, this time, inside the boiler room. His sister, Sasha, screams as she and her friends are being attacked, and she is heard from the other side of the prison, where Rick Grimes' group is. Rick's son Carl heads to the room, and after helping Tyreese by killing some of the walkers, he takes the group safely into the other side of the Prison. Tyreese attempts to kill Donna with his hammer to avoid reanimation. He doesn't manage to do it because of distractions. At this point, Tyreese and Sasha view that Carl, Beth Greene, and her father Hershel have not allowed their entry to the cell block, as Carl locked them out. Sasha argues with Carl over locking them out and demands that he and Hershel let them inside, but Tyreese calms the situation down by telling his sister that they had never been in a better place for weeks, and she should leave Carl alone.
Tyreese is at the common room telling Hershel how he managed to survive through the past months. Later, when Tyreese and his group go outside to bury Donna, he starts arguing with Ben and Allen over them planning to take over the prison. Tyreese disagrees with them, stating that Rick's group are good people, and that they don't want any trouble, unaware there are more survivors that make up the Prison group. When Rick decides their fate, he has a vision of his deceased wife Lori, which causes him to lash out and order her to leave, which causes Tyreese's group to flee in fear (believing Rick was yelling at them).
Tyreese and his group run into Milton Mamet and Andrea during their journey from the prison. Milton and Andrea tell them about Woodbury, and Milton offers to take them there. He and the group arrive in Woodbury, where they are greeted by The Governor. Tyreese mentions the prison to Philip, and says that he can provide some details about the layout of the prison and offers to help defend Woodbury from the prison group.
Tyreese and Sasha are seen guarding the wall and Sasha makes fun of how a poor shot Tyreese when Andrea tries to lure them away to another part of the wall. When they refuse, she confesses that she's leaving Woodbury. "The Governor is not what he seems to be," she warns before fleeing. They inform The Governor about Andrea's escape and Tyreese asks "This isn't a prison camp, is it?" The Governor reassures them no and that he's merely concerned for Andrea's safety.
Back in Woodbury, Tyreese is yelled at by Allen for jeopardizing their standing with The Governor. Allen then blames Tyreese for a prior encounter where he saved Donna in front of his family, emasculating Allen (in his eyes) in front of his family. They are brought by Caesar Martinez to a walker pit and are asked for help rounding up the dead. Tyreese realizes that the Walkers will be used to tear the prison survivors apart and refuses to participate in the plan. He offers to leave Woodbury; Allen steps in and the two fight, nearly resulting in Tyreese dropping Allen into the walker pit, but he relents at the last second. Tyreese and Sasha confront the Governor about keeping captive biters, but the Governor tells Tyreese and Sasha that the pit walkers are just a scare tactic and were never intended to kill people. Not fully convinced, Tyreese nevertheless apologizes for being difficult.
Tyreese is seen being told to gear up and head out to the prison, but he and Sasha both decline, offering to guard the children and elderly. That night, they encounter Karen along with Rick's group and demand to know what's going on. Tyreese is told that The Governor went mad and killed the soldiers who were trying to retreat and is horrified when he sees the room where Andrea is held hostage in. Both he and Sasha commandeer a bus and use it to transport the other survivors from Woodbury to the prison and they formally join Rick's group.
Tyreese is seen paying Karen a visit and kisses her. He talks about the supply run with her and offers to help her kill the walkers so they could spend time together.
Sasha is seen readying a vehicle with Tyreese to go on a supply run to Big Spot. Bob Stookey asks her if he can go. She is initially reluctant to let him come along, saying he has only been with them a week. "You were out on your own when Daryl found you. I just want to make sure you know how to play on a team," she tells him, but ultimately decides to let him come.
At Big Spot, Sasha lays out the group's plan to get in and get out. Things go awry when Bob accidentally breaks a shelf, which lands on him. Walkers suddenly begin falling in from holes in the ceiling. Zach is bitten by one while saving Bob. A helicopter makes the roof cave in, crushing Zach and the walkers while Tyreese and the others escape.
Later that night, Tyreese and Karen are seen in their cell talking to one another before going to sleep. Karen tells him that she is not ready to start sleeping with him, since she knows that they would never want to stop once they start. She sends him back to his own cell to sleep.
Tyreese is seen with Karen. He starts singing to her until she leaves for her cell block. Later on, Tyreese saves Karen during the walker attack on Cell Block D. She then is seen coughing and being brought to Tyreese's cell. However, the Council decides to take her away from the healthy people as they discovered there is a disease that kills people. When Tyreese goes to visit her, he finds a blood trail that leads outside. He finds two burned corpses, one of them being Karen- he identifies her by her singed bracelet and the other being David.
Carol Peletier, Rick, and Daryl meet Tyreese in the courtyard. Tyreese explains that he came to see Karen, but instead found a blood trail leading to the sight of her and David murdered in cold blood. Tyreese then approaches Rick, demanding him to use his cop-skills to find out who did it. When Tyreese starts to become physical with Daryl, Rick tries to conciliate Tyreese, but he pummels Rick twice before Daryl grabs him. Rick fights back, and repeatedly pummels Tyreese in the face, both breaking his own hand and giving Tyreese a wounded eye. Daryl restrains Rick, preventing the latter from doing anymore harm. Tyreese is later seen digging two graves for Karen and David. Bob finds him doing this, and tries to convince him to get his eye looked at. Tyreese declines and says that he won't do so until the bodies are buried. Bob decides to lend a hand, and starts to help him dig a second grave.
Daryl later finds him and asks if he wants to help the group's supply team, whose aim is to retrieve medical supplies from a far off college. He, however, turns down the offer, but later joins them after seeing Sasha's condition. During the drive to the college with Daryl, Bob, and Michonne, a radio transmission can be heard. Daryl attempts to tune the radio in, however, he crashes into a walker and almost drives into a walker herd. The supply group is quickly surrounded by the herd and decide to make a run for it. After everyone abandoned the car, Tyreese just sat inside of it, glaring at the walkers outside. Everyone but Tyreese manages to make it out of herd's range. Tyreese gets converged by walkers when he exits the car. He starts to fight them off with his hammer. The group decides to leave him behind, believing that there is no way that he can survive. Moments later, however, when the supply group have managed to escape into a forest clearing, they hear the bushes behind them rustle. Two walkers burst out, however, Tyreese follows through seconds later and smashes one in the head. He falls to the ground, exhausted, and is helped up by Daryl before more walkers catch up.
Tyreese and his supply-group continue to walk to find another vehicle, as they were forced to ditch their former one, due to a massive herd. They find an auto-shop, and after clearing some ivy, find a minivan, which just needs a battery. A few walkers are inside and the group proceeds to clean them out. As the group chops away at the overgrowth, Tyreese, still unhappy with Karen's death, cuts too fast and pulls at a door, releasing the auto-shop's walkers. The group kills them after a struggle, but Tyreese refuses to let go of his walker, still trapped in the ivy. He eventually pulls it out and they struggle before the others kill it. While scavenging the veterinary college for medical supplies, Daryl and his supply-group are ambushed by walkers who have seemingly died from the same flu-like disease present in the Prison. Tyreese helps the group escape by throwing a fire extinguisher through the window and they all jump onto the roof of an outside walkway. Bob almost loses his bag but manages to retrieve it. Daryl finds there is nothing in his bag but a bottle of liquor, which he attempts to throw away. Bob puts his hand on his holster, pleading with Daryl to give him the bottle back. Daryl, un-intimidated, disarms Bob and grabs him until Tyreese breaks them up, saying that Bob has already made his choice. Daryl says that they should have never allowed Bob into the prison group, and that he will beat him into the ground if he drinks even a sip of liquor before the sick prisoners take the medicine.
When Tyreese is approached by Rick and Daryl, both of whom want to talk about the killings of Karen and David, he persuades Rick to see what he found: a tortured and mutilated rat. After stating that the one who killed Karen and David and fed the walkers through the fence with rats is the same person and a psychopath, Rick tells him that it is impossible. Before Rick gets the chance to tell him why, the Governor's tank shot a shell, blowing up a guard tower and making a lot of noise. Tyreese and the other able survivors rush outside of the prison to meet the armed force. After negotiation with The Governor failed and Hershel is killed, Tyreese is seen holding a M1 rifle and participated in the prison defense with other survivors. After The Governor broke down the fence with his men, Tyreese, who is known for his bad aptitude with a gun, was being pushed back while fighting Alisha and another unnamed soldier. After being pushed back behind flower pots, he is saved by Lizzie and Mika Samuels, the former of whom kills both Alisha and the unnamed soldier. After he tells them they need to leave, he yells at the two, telling them that they are going the wrong way. He follows them and finds an abandoned Judith, where he picks her up and runs with the other girls
Tyreese is seen walking through the woods with Mika and Lizzie, with baby Judith, whom they managed to take with them while fleeing the prison, strapped to his chest. Tyreese does his best to cope with a crying Judith, a grim, determined Lizzie, and a terrified Mika. When Mika becomes so frightened that she runs off further into the forest, Tyreese finds her and calms her down. During this encounter, Tyreese gets a scratch on his arm, which worries Lizzie.
Tyreese hears screams from the railroad tracks, and leaves Judith with the girls to try to see if it's someone from their group. Tyreese helps the group kill the various walkers who have attacked them, but is ultimately the only survivor of the conflict. As he prepares to go back to the girls, he turns around to see them standing near him, along with Carol, who is holding Judith. Tyreese, who knows nothing of the reason why Carol wasn't at the prison during the fall, greets her warmly.
Before turning, the last remaining survivor tells them of a safe haven known as Terminus. They decide to try to find it.
Tyreese is first seen with Carol, Lizzie, Mika, and Judith, sleeping on the railroad, while Carol and Lizzie are speaking. He is having nightmares and speaking in his sleep, repeating the word "no". While on the railroad tracks with Judith and Lizzie, Tyreese prepares to kill a walker which got stuck on the train tracks, but is stopped by Lizzie, who tells him she understands walkers have to be killed sometimes, but sometimes they don't. While they are boiling water, Tyreese looks out the window to find Lizzie scolding Carol about killing a walker. As Tyreese and Carol set out to scout the woods for deer, they come back to camp to find Mika's lifeless body and Lizzie holding her knife, her hand dripping with blood, in an attempt to show Carol and Tyreese that the walkers aren't different, and that she was preparing to kill Judith too. Tyreese tells Carol that Lizzie admitted to feeding mice to the walkers at the prison and also killing the dissected rabbit he found in the tombs the day of the Governor's attack. Tyreese also believes she killed Karen and David, but Carol counters that Lizzie would have allowed them to turn. After Carol executes Lizzie, the two bury the sisters next to each other, Tyreese carries the body of Lizzie and places her in the grave. As they are sitting in the darkened room, she slides her revolver across the table to Tyreese and admits that she killed Karen and David in an attempt to keep the flu from spreading to the other survivors, and that Tyreese can do what he has to do. Tyreese takes his hand off the revolver, telling Carol he forgives her but he will never forget what she did, and that it has now become a part of who Carol is. Tyreese and Carol are last seen departing the grove house as voiceovers of Lizzie, Mika and Carol are heard.
Tyreese and Carol are seen walking on the railroad tracks when they hear gunshots coming from Terminus and a herd of walkers headed in that direction. After hiding, they come across a shack and a member of Terminus named Martin, who mentions Michonne and Carl as he communicates with Cynthia (another member of Terminus) while planting fireworks. Tyreese and Carol overhear this while they get the drop on Martin, binding his hands with a seat belt in the shack as she sets off to rescue the others. Martin tells Tyreese to take a car and Judith and get out of there alive. When Tyreese turns his back to Martin when a herd of walkers approach, Martin lunges towards Judith and puts his hands around her neck, threatening to break it and orders Tyreese to go outside and face the herd of walkers. Tyreese, however, kills them all and tackles Martin to the ground of the shack, punching him several times and saying that he is not going to kill him. When Rick and the others show up, Tyreese tells Carol that he killed the man because he was threatening to kill Judith.
Tyreese is seen traveling with the group. At some point, while Tyreese and Carol are refilling their water, he tells Carol she needs to tell the group about Karen and David and that they'd have to understand. He doesn't want her to talk about Lizzie and Mika, however, because he wants to forget about it. Later, Tyreese looks on as Bob and Sasha play a game called Bad out of the Good, which Sasha explains to him. He's present when the group rescues Father Gabriel Stokes and they go to his church. Tyreese volunteers to stay behind and look after Judith while the others go for supplies, for which Rick is grateful. Later that night, he is eating and celebrating with the group as Rick decides they're heading to Washington D.C.
Tyreese grabs Sasha in the woods when she is looking for Bob. He takes her back to the church for safety. He is seen listening to Gabriel's confessions. When Bob is brought in from outside Tyreese watches. Tyreese does not take part in the massacre of the cannibals, instead remaining inside the church with Judith, Carl, Eugene Porter, Rosita Espinosa, and Bob. Before they leave he tries to persuade Sasha to stay with Bob for when he wakes up. She hands him a knife in case he doesn't. He watches the massacre in shock when it happens. When Bob dies, Tyreese stops Sasha from preventing his reanimation, instead dealing with it himself. The next day he digs graves for the cannibals and Rick joins him. When Rick asks him how the journey to Terminus went he replies 'it killed me'. Rick tells him that it didn't. He stays behind with his sister when the group splits up, choosing to remain at the church.
Tyreese is present with Rick, Daryl, Sasha, and Noah on a mission to rescue Beth and Carol from Grady Memorial Hospital. He forms a plan that is peaceful rather than violent to make sure that nobody dies. The group decide to go with his plan.
Tyreese is shown with the group after Rick kills Bob, the other officers agreed to lie about Bob being eaten by walkers. He is seen on the roof-top with Sasha as they watch over Rick, who is making himself known to the police officers at the hospital. Tyreese confesses to Sasha that he previously had the chance to kill Martin, the Terminant Sasha murdered, but didn't. Tyreese then asks what happened to them and wonders if they're still the same as they were as kids. Sasha dismisses this and tells him that he is still the same, which is a good thing, but she can't be anymore. The two then proceed to watch over Rick. Sasha shoots an incoming walker, revealing to the officers that Rick has people covering him.
Tyreese later accompanies Rick and the others as they meet with Dawn to exchange prisoners. It goes smoothly, and Carol and Beth are returned safely, but Dawn insists that Noah return to the hospital. Her insistence results in tension, but Noah agrees to prevent further bloodshed. Dawn makes a snide remark to Noah, which angers Beth, who attacks her with a pair of scissors. Dawn reacts instinctively and shoots Beth in the head, killing her instantly. Tyreese and the others witness this in shock and horror. Daryl, enraged, shoots Dawn in the head, killing her as well. Officer Shepherd defuses the situation and tells them that Dawn was always the problem. The group are invited to stay at the hospital, but Rick refuses and in return demands that anybody who wants to leave the hospital be allowed to do so with him. Only Noah agrees to leave.
The group depart the hospital just as Maggie, Abraham Ford, Glenn, Michonne, and the others arrive. Tyreese watches on in helplessness as Maggie sobs hysterically at the sight of Beth's body, which is being carried out of the hospital by a devastated Daryl.
After the loss of Beth, the group decide to head to Virginia and find the compound that Noah came from. Tyreese joins Noah and a group consisting of Rick, Michonne, and Glenn as they head into the estate to investigate while Carol and the others remain behind. On the journey, Noah tells Tyreese that he made the right call by suggesting the exchange at the hospital, but Tyreese isn't so sure. Tyreese then tells Noah and the others about his father, who used to tell him and Sasha to always watch and listen to the news so that they have their eyes open about the atrocities that take place in the world.
Upon discovering that the community is lost and everybody inside it dead, Noah breaks down and Tyreese remains behind to comfort him while Rick and the others decide to scavenge for supplies. Tyreese tells Noah about the time after Karen's death when he allowed a group of walkers to overwhelm him in the hope that he could take his anger out on all of them until they killed him, but that he continued fighting and decided to live and because he did, he was able to save Judith. Noah climbs to his feet and runs to his house, with Tyreese in pursuit.
Upon entering, they find Noah's mother dead. Tyreese wanders around while Noah sits by his mother's corpse. Whilst inspecting some family photos, Tyreese is bitten in the arm by Noah's reanimated brother. Noah runs off to get help. Tyreese suffers severe blood loss and begins to hallucinate about news stories on the radio as well as visits by Martin, Bob, The Governor, Lizzie, Mika, and Beth, who discuss his actions throughout his time with the group. Tyreese struggles internally with his recent decisions and 'speaks' with his hallucinations. Bob, Beth and the girls try to comfort and reassure him that he did the right thing and that death is much better than being alive, but the Governor and Martin antagonize him for not being able to do what they feel needed to be done. A walker attacks him again, and in order to save himself, he feeds it his wounded arm in order to grab a weapon.
Shortly after, Michonne amputates Tyreese's bitten arm and she and the others suffer a grueling challenge in escaping the estate with a seriously wounded Tyreese. During the ride back, Tyreese is comforted by visions of Beth, Bob, and the girls. He tells "Bob" to turn off the radio, effectively deciding that he wants to let go. He passes away and is sadly put down by Michonne so that he doesn't reanimate. The rest of the survivors then attend his funeral which Gabriel presides over. A visibly traumatized Sasha is seen struggling about to just stand through the service.
While observing pictures of Noah and his brothers, Noah's zombified brother sneaks behind Tyreese and bites him in the arm before Noah puts the walker down. Then, as he starts hallucinating with the Governor, he is bitten again by another walker.
In order to prevent infection from spreading, Michonne amputates his arm and the group tries to take him back to the rest to repair the damage, but eventually he dies from blood loss. Later, Michonne stabs him in the head off-screen to prevent reanimation.
Sasha is Tyreese's younger sister. Surviving together, they have made a good team with Allen and his family. She seems to have different viewpoints on crucial decisions Tyreese makes. However, she and Tyreese both disapprove of Allen and Ben's plan to overtake the prison in "The Suicide King". In "Prey" Sasha pokes fun at Tyreese's poor shooting skills, showing that the pair like joking around with each other. Later in the same episode, Tyreese starts to fight with Allen and almost kills him, but as soon as Sasha tells Tyreese not to, he stops. This shows that the two have a loving and caring relationship. When Tyreese finds out that The Governor killed his own men, both he and Sasha decide to leave Woodbury with Rick to go back to the prison in order to keep each other safe from The Governor for when, or if, he returns.
When Tyreese found out that Sasha was sick, he became extremely saddened and decided to go on the supply run with the priority to find her a cure. He left her on a touching goodbye, and told her to get some rest. This, coupled with Karen's death, later caused him to fight the massive walker herd in a suicidal rage. After the supply run for medicine, Tyreese and the group return with a cure, and Tyreese happily reunites with his sister.
Tyreese and Sasha are separated during the fall of the prison. Although he is busy trying to help keep Lizzie, Mika, and Judith safe, he's clearly concerned about Sasha's safety when Lizzie says that Sasha is likely dead. Sasha on the other hand, agrees to head to Terminus, stating that her brother could still be alive and be there, showing that the two care for one another's safety. He is extremely happy to be reunited with her. The two continued to be close until Bob's death, which made Sasha a bit cold, causing Tyreese a bit of unease as he tries many times to persuade her that things will go back to the way they used to and that she, like him, should have a positive outlook, but is unsuccessful. His death then became another driving factor for Sasha's current cold personality, to the point where she'd hunt down random walkers on her own on their stay in Alexandria. Later his and Bob's death has affected her so much that she does to Gabriel for guidance but he declines her and, in an attempt to make her kill him, disgraces Tyreese's memory, after blaming her for Bob's death, which causes her and attack him in rage and almost kill him only being stopped by Maggie's intervention.
"I dream about Karen. I see her every night. And every time I forget she's dead. Sometimes, we just talk. And sometimes, I see her in the crowd... in a city I've never been to. And it's back before everything happened. And then... some nights, the bad ones... I see someone kill her. Some stranger. Then I lose her all over again."
After becoming the sole survivor of the Governor's assault on his own militia, Karen is rescued by Rick's group and she in turn takes them to Woodbury. Tyreese is initially hesitant in allowing the group inside until Karen reveals herself to be alive, detailing that the Governor fired on his own people and that Rick's people saved her. In Season 4, it is revealed that Tyreese and Karen have formed an intimate relationship and Tyreese volunteered to kill the walkers on the fence so he could get to know her better. Upon Karen's death, Tyreese breaks down on the ground and starts to cry. As seen in "Isolation" and "Too Far Gone", he seeks revenge on someone who killed Karen. When he does find out Carol killed Karen, he asks if it was quick, hoping she felt no pain. He comes to forgive her, which he later explains is because "it's not over."
Allen is Tyreese's friend and he and his family are the first people Tyreese and Sasha met after running out of supplies in their neighbors bunker. Tyreese and Allen seem to get along and work well as a team. When Donna was bit, Sasha informed the group they need to kill her before Donna kills them, but Tyreese and Allen told Sasha that Allen and Ben should not have to do this and do it somewhere private, safe, and away from Donna's family. When Allen mentions taking over the prison, Tyreese and Sasha both disapprove and Tyreese manages to convince Allen that it would be more beneficial for them to convince the prison group to allow them to join, rather than overtake them. This shows that Allen trusts Tyreese's judgement to some degree. Though it was originally shown that they were good friends, in "Prey" it is revealed that Allen harbors a grudge on Tyreese. According to Allen, at some point Tyreese saved Donna from a walker when Allen could have, and the way Donna revered Tyreese cause bitterness between the two men. Allen also states that Tyreese "showed him up" in front of Ben. In "Prey", the two argue, as Allen attempts to talk Tyreese out of causing trouble with The Governor. The two engage in a physical fight after Tyreese and Sasha refuse to help collect walkers from the "biter pit". Tyreese gets infuriated to the point that he almost shoves Allen into the pit, but decides against it. The two seem to be on unsteady ground after this altercation, and it seems that their apparent friendship has been severed. However despite this Tyreese and Sasha appear horrified to learn that Allen, along with every other Woodbury citizen in The Governor's army, had been killed by The Governor.
Donna seemed to respect Tyreese as a friend and the leader of their group. When Sasha proposes to leave a bitten Donna for the walkers, Tyreese refuses to do so. Following Donna's death, Tyreese was saddened and volunteered to prevent her reanimation. At Woodbury, Allen mentions that Donna was "glued" to Tyreese after he saved Donna from a walker some time before they came to the Prison, much to Allen's dismay.
Ben seemed to respect Tyreese as a friend and the leader of their group. When Sasha proposes to leave a bitten Donna for the walkers, Tyreese refuses to do so, stating that Ben is not ready to lose his mother. Following Donna's death, Tyreese volunteered to prevent her reanimation, not wanting Ben to do it. Their relationship started to be hostile when Tyreese fought with Allen, with Ben yelling at Tyreese to leave his father alone. Tyreese's reaction to Ben's death is unknown.
Upon meeting Tyreese, Rick is distrustful of him and tells him that he could not stay with them. Tyreese offers his help and tries to convince Rick into letting him join, but leaves without any arguments when Rick shouts at him to get out [Rick was actually shouting at a hallucination of Lori]. At Woodbury, while Allen says that Rick is a whack job to The Governor, Tyreese understands why Rick is a little unhinged.
Rick later lets Tyreese rejoin the prison group and comes to trust him as a member of their group. When Karen is murdered in cold blood, Tyreese is unhinged, just like Rick was months before. He angrily attacks Rick, only to be held back by Daryl. Rick takes advantage and retaliates, brutally beating Tyreese. Later, Rick apologizes for what happened earlier, and promises that he will find out who murdered Karen. Tyreese, however, blames Rick for pumping water for the sick residents rather than find out who murdered Karen. Tyreese leaves with Bob, Daryl, and Michonne to find medicine for Sasha. When he returns, he is on civil enough terms with Rick to confide in him about the mutilated animal he found. The fall of the prison and separation of most of the group impede any further relationship between the two men.
Tyreese cares for Judith when the group is separated, and he is very happy to see them reunited. Rick and Tyreese's friendship is strengthened, and Ty shows his readiness to help Rick and the group, despite what happened before. During the events of season five, the two men became closer friends. When Tyreese got bit, Rick tried to save him but it was already too late. Rick was deeply saddened by Ty's death, his daughter's savior.
After hearing the screaming of Tyreese's group being attacked inside the prison, Carl goes to investigate. Carl helps the group and brings them to safety. He then locks them inside a room, as the group was unsure what to do with them. While Sasha is upset and yells at him for locking them up, Tyreese is understanding and respects Carl for saving him and his group. Carl was later angry about Rick's decision to let Tyreese join the prison but as time goes on, the two have formed a friendship and get along well. Carl was shown saddened by his death at his funeral.
During his escape from the prison, Tyreese finds Judith unattended to and saves her. Alongside Lizzie and Mika, Tyreese has taken a liking to Judith and frequently looks after her on their journey to Terminus. Tyreese developed a protectiveness over Judith and risked his life, unarmed, against a pack of walkers to save her from Martin. Later when Rick asks Tyreese to take care of Judith whilst he goes on a supply run he happily accepts, showing that Tyreese still cares for her.
Tyreese did not have much initial interaction with Carol, but it can be assumed that they had a fairly good relationship with each other. Carol is one of the people who stays behind at the prison while most of the men leave to free Maggie and Glenn from the Governor's clutches. Tyreese and his group arrive at the prison around this time. Carol and the others keep the group locked up, as a precaution, but give them food and water and allow them to bury their dead (Donna). Carol seems to have no problem with Tyreese's group joining the prison permanently.
Eventually, Tyreese and Sasha return to the prison, and he presumably gets to know Carol better. In "Isolation," Carol is shocked and distraught as Tyreese fights with Rick upon discovery of his girlfriend Karen's charred remains. Tyreese is devastated, but before he leaves to find medicine for Sasha, he lets Carol know how he appreciates her support.
Unbeknownst to Tyreese, Carol is the one who killed Karen (along with another man, David, who was also ill). Carol confides her actions in Rick, who, disturbed by her lack of remorse, banishes her in "Indifference," while Tyreese is still away from the prison. When Rick is about to inform Tyreese of the situation in "Too Far Gone", The Governor and his militia arrive at the prison.
Tyreese flees the prison with Lizzie and Mika (the little girls Carol had agreed to raise), along with baby Judith. After some time on the road, Carol finds the girls and they go to Tyreese (who'd left them in the woods because he heard yelling on the train tracks). Initially, Carol believes Tyreese knows the truth and will harm her, but instead, he hugs her. Tyreese is delighted at Carol's reappearance because he thought Carol had died (Rick returning to the prison alone made him think so.) Carol chooses to keep quiet about her role in the murders. They continue to follow the tracks to try to find Terminus.
In "The Grove", he and Carol have become closer, with Carol treating the infection on his arm and sharing in taking care of the girls. After they find a small cottage to rest in, Tyreese even says he would be happy starting a life there with Carol and the children, because he trusts her. After Carol executes Lizzie (due to Lizzie killing her sister and nearly killing Judith), she, exhausted and guilt-ridden, confesses to Karen and David's murders, placing a revolver on the table to let him decide her fate. Tyreese is shocked and grabs the revolver, but says he forgives her and lets go of it, but he would never forget what she had done because it has now become a part of who she is. He tells Carol they can't stay at the cottage now, and they, along with Judith, resume their search for Terminus.
When Daryl returned to the church without Carol, Tyreese volunteers to go find her in Atlanta. After finding Carol in the hospital, Tyreese helps Carol out of the hospital. Carol was shown to be saddened by Tyreese's death.
—Glenn to Rick and Noah, ordering them to help Tyreese[src]
Glenn accepted Tyreese and his group into the prison after first meeting them, and vowed to put in a good word for them with Rick. Despite Glenn's and Hershel's words, Rick still throws them out after remembering what the last result of trusting other strangers was.
When the prison members officially opened their doors to survivors, Glenn and Tyreese seemed to be on good terms, going on supply runs together, though Tyreese admits he went on the supply run for a different reason. Glenn separates Tyreese and Karen once he learns of her sickness. Glenn does not take sides in the argument between Rick, Daryl and Tyreese because he himself had fallen sick to the influenza at the prison.
Glenn and Tyreese do not interact for the rest of the season, but he shares hope with Sasha that he may still be alive, showing that he saw Tyreese as a strong individual.
Glenn and Maggie remain behind with Tyreese, Judith, Bob, Eugene and Gabriel, all of whom are horrified at Rick's orchestrated massacre of the remaining Terminants.
Glenn leaves with Abraham while Tyreese stayed with Rick, cutting off communication between the two for a large period of time. When Noah was to be brought back to his community, Glenn left his grieving wife to help Tyreese get him there. Glenn was shown to be concerned for Tyreese after seeing him bitten and amputated, and defended him from a horde of walkers at the gates. Glenn stood over Tyreese's corpse remorsefully at the end of Tyreese's life.
"Oh, there you are. Took me damn forever to find you. Whatcha doing? (...) Man, I want to find them too. Put a bolt in them for what they did. These people are cut off. Ain't no way anyone's getting in and out without a whole bunch of people seeing 'em. Standing guard ain't gonna do no good unless we come back with them meds, alright? We're gassing up by the front gate in case you change your mind."
Tyreese did not have much initial interaction with Daryl, but it can be assumed that they had a fairly good relationship with each other. When the remaining Woodbury residents are brought to the prison, Daryl goes along with it, showing that he trusts Tyreese as a friend. After Karen is murdered, Daryl promises to find her murderer, and tries to calm Tyreese down. Tyreese pins Daryl to a wall, and Daryl replies that the two are on the same side. Daryl later requests for Tyreese's help for the supply run, and is grateful towards him when he agrees. Daryl is relieved to see Tyreese alive after his run in with a herd of walkers, and the two continue working with each other during their supply run.
Tyreese went with Daryl to Atlanta to find Beth and Carol, and the two coordinate evenly while discussing a plan to free their kidnapped people. They both agree in making a trade between hostages of both sides. Daryl was deeply saddened by his friend's death later remarking to Maggie that despite his emotional flaws Tyreese was tough, showing the respect Daryl had for him.
Tyreese met Andrea outside of Woodbury before she left to meet the group in the prison. During their few interactions, it is shown that Tyreese viewed her positively, but respected Philip more than her when a member of Woodbury. He told her not to leave when she tried to escape quietly, resulting in her threatening him. Tyreese was shown to be saddened when discovering her bite, but it is unclear if her death truly affected him in the long term.
Hershel and Tyreese have formed a quick friendship upon meeting each other. Tyreese is grateful towards Hershel for offering to help, and promises to do whatever he can for him and the prison group. Hershel later tries to convince Rick into letting Tyreese and his group stay in the prison and to give them a chance at earning their place, showing that he trusts Tyreese after getting to know him. When the Woodbury residents including Tyreese join the prison, Hershel is happy to see him again and gives him a friendly pat on the shoulder. In the following months, Tyreese and Hershel have established a good friendship. Tyreese is grateful towards Hershel for saving Sasha and the other sick prison residents' lives. After Hershel was decapitated by the Governor, Tyreese mercilessly fired at The Governor's Militia, enraged over the death of his friend.
Beth and Tyreese interacted very little, however, the two seem to be on good terms with each other. It seems that Tyreese is appreciative of Beth when she and Axel handed the equipment to his group in order to bury Donna. In Season 5, Tyreese appears to care about Beth and what she means to the group as he comes to help the group get her back after her abduction. Beth's death is witnessed by Tyreese as he watches her get shot in the head, and is clearly upset that she died. He ultimately feels bad, along with the rest of the group, that he couldn't do more to prevent her death. When Tyreese is dying, he sees Beth as a hallucination, and she tells him that everything is going to be okay and that it's better when you are dead.
Tyreese and his group meet The Governor and ask to stay in Woodbury. The group explains to The Governor that they were kicked out of the prison and offer information about The Prison and the group. Tyreese wants to help defend against Woodbury's enemies, but The Governor rejects their offer. Tyreese later finds out how deranged and evil The Governor really is and he resolves to take as many survivors as possible and flee Woodbury, severing any type of friendship between the two. Tyreese later participates in the bloody battle which kills the Governor along with many others on both sides. When Tyreese is dying of a walker The Governor appears as one of his hallucinations who antagonizes him over his failure to adapt to the new world, but Tyreese simply scolds him and his cold ways.
For most of their time at the prison, Tyreese and Michonne participate in group supply runs together. Tyreese and Michonne talk about the former's suicidal rage, where Michonne shows to care about Tyreese's well being, implying a stable relationship. Michonne is relieved to see Tyreese alive after his run in with a herd of walkers. The group later discovers a car parked at an auto shop, but it is covered by vines and tree bushes. As they cut through the bushes, Tyreese relentlessly hacks away, knocking the handle off a door. Walkers begin coming through the bushes and Tyreese gets tackled by one because he wouldn't let it go. Michonne and Tyreese later hack at the bushes together, and Michonne tells him that he has every right to be angry, but his anger would make him stupid and get him killed. Tyreese asks her if she is still angry about the Governor. Michonne says that she would cut him in half if he was standing there, but not because she's angry, but because it needs to be done. Tyreese asks her why she is still looking for him, to which she replies she doesn't know.
Michonne later cuts off Tyreese's arm to try and save his life after getting bitten. Her attempts to protect him extended to helping getting him out of the fallen haven and carrying him past several walkers and defenses. She was devastated by his death, but still made sure he did not reanimate by stabbing him through the brain. When Sasha became reckless, consumed with grief, Michonne would use Tyreese as a reason to calm her down.
"I'm gonna say it and you're gonna listen. And then when you're ready, you let me help you. You got to say goodbye. He saw it, he felt it. And you hold onto whetever you want to, but i think you should hold on to that. You could've. But you let yourself feel it. Kept your eyes open. You let me help you."
Bob comes to Tyreese at the prison asking if he can do his part to help out. It is possible Bob looks to Tyreese as a leader, for he goes to him to ask about how he can do his part. Bob also shows horrified concern when Tyreese is swarmed by a large group of walkers. He also showed concern after Tyreese and Rick had a fight, and told him to check on his wounds. When Daryl finds out that Bob took the wine, he stops him from killing Bob, saying he made his choice and to let it go. After escaping Terminus, Tyreese doesn't mind Bob being in a relationship with his sister, showing that he approves of their relationship and trusts Bob. Tyreese stabs Bob in the head after his death to make sure his sister didn't have to, feeling remorseful whilst doing so, showing how saddened he has become by his death. Later Tyreese himself is dying of a walker bite Bob reappears as one of the hallucinations who try to comfort him before he dies.
"I brought her some food. Cleared out her room. Made sure she doesn't have any knives. Anything like that. She has a shoe box full of mice. I asked her if she was the one feeding the walkers at the prison. That was her. And at the tombs, we found this rabbit, pulled apart and nailed to a board. That was her, too. Said she was just having fun. I was thinking, maybe she killed Karen and David. But I don't know how she could drag them away."
—Tyreese to Carol, regarding Lizzie's mental state[src]
Tyreese and Lizzie have a stable relationship during their stay at the prison. During the governor's attack, Tyreese is grateful towards Lizzie for saving his life, and escapes the prison with her. On the road, Tyreese does his best to keep the girls, along with baby Judith, safe. He is at times thrown by Lizzie's bleak worldview, like when she flatly tells him Sasha is dead.
When he and the girls reunite with Carol and they find an abandoned cottage, Tyreese enjoys their time together, even suggesting they settle down there. Later, when Carol and Tyreese see that Lizzie has murdered her sister and is about to kill Judith, Tyreese is horrified. He then assumes that she killed Karen and David because of her psychotic tendencies, and agrees with Carol when she suggests that Lizzie should be executed for the safety of everyone else. He buries Lizzie and Mika in the grove before he, Carol, and Judith return to the road and towards Terminus. When Tyreese is dying of a walker bite Lizzie appears as one of his hallucinations who try to comfort him before he dies.
Tyreese and Mika have a stable relationship during their stay at the prison. During the governor's attack, Tyreese is grateful towards Mika for saving his life, and escapes the prison with her. After escaping the prison, Tyreese does his best to help Mika keep going, understanding and supporting her when she runs off and when she cries over not being as strong as Lizzie. Tyreese continues to look after and care for Mika after Carol's return. When he and the girls reunite with Carol and they find an abandoned cottage, Tyreese enjoys their time together, even suggesting they settle down there. Tyreese is shocked and saddened upon finding out that Mika was murdered by her own sister. When Tyreese is dying of a walker bite Mika appears as one of his hallucinations who try to comfort him before he dies.
Martin seemed to respect Tyreese in their short time together. However after Rick and the group destroyed Terminus, any respect Martin had for Tyreese was lost and he began to despise him. Despite this, Tyreese was visibly disturbed when Sasha brutally kills him. In Tyreese's final moments, Martin is one of the many people he hallucinates over, showing how much of an impact he had on Tyreese, though this may have been because he viewed his handling of Martin to be one of his biggest mistakes and deepest regrets. He went as far to quote him, saying how people like himself don't get to make it. When Tyreese is dying of a walker bite Martin appears as once of his hallucinations where he, and The Governor, antagonize him for his failure to do what's needed.
Tyreese and Gabriel didn't interact much. Like the other group members Tyreese was suspicious of Gabriel upon their meeting and Tyreese appeared disturbed by Gabriel's confession. When Tyreese died from a walker bite Gabriel presided over his grave, reading verses from his bible, as the group members buried him. When Gabriel declined Sasha help with he grievances he coldly remarked that Tyreese didn't deserve to live causing Sasha to attack him, but this may have only been a cowardly tactic to make Sasha kill him.
Tyreese and Noah presumably had not spoken to one another very much, until What Happened and What's Going On, where Tyreese encouraged Noah, after finding the Shirewilt Estates in ruins and overrun by walkers. Tyreese is attacked by walkers in Noah's home, Noah saves Tyreese, and runs for help and appears distraught by his death after trying desperately to save him.
Next to Abraham, Tyreese is one of the strongest members of Rick's Group, shown by his use of a hammer to kill walkers, as well as the fact he was able to hold Daryl in place against a wall.
In the list of action figures expected to be released, Tyreese's last name is mentioned to be "Williams". This is confirmed to be his actual last name in the show in the "Tyreese's Journey" bonus feature on the Season 5 DVD.
Tyreese may be ambidextrous or left handed, as he is shown aiming with his left eye and left hand throughout the series, but wields his trademark hammer in his right hand.
Tyreese is the first main character to die during a mid-season premiere, the second being Jessie and the third being Carl Grimes.
Tyreese is one of the three (determinately five) characters in The Walking Dead universe to die of infection even though they amputated the infected limb. The other characters include both Allen and Morgan from the comic series and determinately Lee Everett and Rufus from the video-games.
Tyreese is one of two main characters to be recognized with a relative "celebrity" status (as a former NFL linebacker). The other is Deanna Monroe who was a congresswoman from Ohio.
