WARNING: The following contains spoilers for The Walking Dead Season 10, Episode 22, "Here's Negan," which aired Sunday on AMC.

While last week dealt with the aftermath of Carol and Daryl's fight, this week's episode, "Here's Negan," finally gives Negan a proper origin story. The episode opens with an icy staredown between Negan and Maggie. Carol observes the interaction from a window. Considering Negan helped Carol get revenge on Alpha, she decides she owes him a favor. Although Negan wants Carol to put in a good word for him with the council, she says what he wants -- to live freely and be accepted -- is not possible. Carol decides it's better if he leaves Alexandria and holds up in the abandoned cabin where Daryl and his former lover used to live.

That night Negan gazes into the fireplace and has a reflective moment. As a result, the "old" Negan, equipped with his trademark leather jacket and barbed wire bat Lucille, appears on the chair behind him. The moment personifies the two sides of Negan: the current Negan, who's exhibited a positive character arch since he was locked up in Alexandria, and the former Negan, who was comfortable being the sadistic leader of the Saviors. The old Negan is quick to remind new Negan, "We got a hell of a lot further with a kind word and good ol' Lucille here than we ever got with just a kind word."

The Walking Dead - Negan and Carol

The mention of Lucille causes Negan to act out, throwing a glass at the chair where old Negan sits. The following day, Negan travels to the spot where Rick slit Negan's throat in Season 8 and digs for his bat. He eventually finds it and removes it from a shallow grave. The discovery prompts a flashback to the apocalypse's early days when Negan's wife, Lucille, is still alive. On a mission to bring back chemotherapy drugs for his wife, who started treatment for her cancer right before the world fell apart, Negan is captured by a group of hostile bikers. They want to know where he got the "rare" refridgerated medicine, considering whoever has it probably has substantial supplies.

Fearing he won't get back to his wife, Negan tells them about a group of doctors that travel a set route, delivering supplies to those who need them. The scene transitions to a flashback from a couple of days prior, depicting Negan trying to rob those same doctors with an empty gun. However, he is knocked unconscious by one of the doctor's daughters, Laura, who -- audiences might remember -- goes on to become one of Negan's people and a high-ranking member of the Saviors.

When Negan comes to, he is inside the doctor's RV. The primary doctor, Franklin, talks to Negan and learns he is trying to acquire more chemotherapy medication for his wife because "something went wrong." The mention of his wife prompts another time transition to six months earlier. Negan is back at his house with Lucille, prepping one of her chemotherapy treatments. She wants to watch a movie, but Negan is worried about a walker outside attracted to the house from the generator's noise. His wife wants him to kill the walker, but Negan refuses, saying he doesn't want to get used to killing.

Later, bored of reading a book, Negan decides to deal with the pesky walker. They engage in a brief struggle before Lucille comes outside and shoots the walker. As the days go by, Negan tries to find gas for the generator and finds an old stash of marijuana, which he brings back to help with Lucille's nausea. Lucille gives Negan an "anniversary" gift over dinner, which ends up being his signature leather jacket. After having a celebratory night, Lucille and Negan wake the next morning to find the generator died, destroying the refrigerated chemotherapy medication.

In a panic, Negan tells Lucille he wants to leave and find the group of doctors he's heard travel around. Lucille yells for him to stop, prompting another flashback to seven months earlier. Now, the word is pre-apocalypse. Negan is playing a video game, and Lucille comes in to yell at him about putting his new leather jacket -- the one she regifts him earlier in the episode -- on a credit card. Money is tight because Negan lost his job as a gym teacher after getting into a bar fight that earned him a misdemeanor assault.

The next day, Lucille learns she has cancer after getting an MRI. She tries calling Negan, who doesn't answer, then calls her friend Janine, who doesn't pick up either. Discovering Negan lied about meeting with his parole officer, Lucille puts two and two together and realizes Negan and her friend Janine are having an affair.

The story jumps forward to Lucille and Negan's conversation after losing the chemotherapy drugs. Lucille tells Negan she knew about the affair. Distraught, Negan promises her he stopped seeing Janine after Lucille got her diagnosis. Lucille tells him he's more than made up for hurting her and wants him to stop trying to get drugs and just be with her. Negan refuses, telling her he won't ever give up.

Another time jump puts Negan back under the captivity of the bikers. The head biker ensures Negan if he tells them where he got the drugs, they'll let him go back to his wife. In turn, Negan rats out the doctors. While the bikers stay true to their word and release Negan, he listens as they raid the doctor's RV violently.

When Negan finally returns to Lucille, the house is quiet. Venturing downstairs, Negan discovers the bedroom door is shut with the words "Please don't leave me like this" and a heart written across the front. Upon opening the door, Negan discovers Lucille is now a walker after committing suicide and tying herself to the bed. Negan grabs a bat, goes outside and proceeds to wrap barbed wire around it, perhaps intending to use it as a weapon to fulfill Lucille's wish of not being left as a walker. Ultimately, he can't go through with it and decides to burn the house -- with Lucille in it -- to the ground.

Donning his leather jacket and armed with his bat, Negan returns to the biker hangout, where they are still interrogating the doctors. Fueled by rage and grief, Negan takes out the outside guards before descending on the head honcho inside. After delivering a lengthy monologue about how he acquired his assault charge, Negan bashes the biker's head in with the bat as he says, "This is for not killing me."

The Walking Dead - Maggie and Hershel

The plot makes its final transition to the present time. After killing a walker with his newly discovered Lucille, the bat cracks down the middle. That night, Negan burns the bat in the cabin fireplace while talking to his dead wife. He apologizes for leaving her, saying he should have been there. He then apologizes for naming "a stupid bat after her." The following day, Negan returns to Alexandria, where Carol meets him at the gate. He tells Carol he wants to retrieve his stuff from the cabin and stay in the community, to which Carol responds, "If you stay here, she will kill you." Although Carol never says who she's talking about, it's clear when Negan once again locks eyes with Maggie; it's her.

As the last episode of Season 10C, "Here's Negan" sets the stage for Maggie and Negan's probable blowout come Season 11. While viewers have watched Negan undergo a tremendous transformation over Season 10, Maggie has not. Even if she had, it's doubtful she'd be willing to forgive him for Glenn's death regardless. This week's episode not only allowed Negan to finally give his wife a proper eulogy and symbolic burial but also his old self. Negan might be convinced his villainous way are behind him, but the rest of Alexandria -- especially Maggie -- isn't so sure.

The Walking Dead stars Norman Reedus, Melissa McBride, Lauren Cohan, Josh McDermitt, Christian Serratos, Jeffrey Dean Morgan, Seth Gilliam, Ross Marquand, Khary Payton and Cooper Andrews. The series airs Sundays at 9 p.m. ET/PT on AMC and is available to stream early on AMC+.
