The Walking Dead is getting audiences ready for a heavy dose of nostalgia in Rick Grimes’ final episode.

Warning: Spoilers will follow for season 9, episode 4 of The Walking Dead.

AMC’s marketing for season 9 hasn’t been the least bit subtle that the first five episodes would be the last for Rick Grimes. Episode 4, “The Obliged,” set the stage and prepared fans for Rick’s exit in episode 5, “About What Comes After.” Given that Rick has been the show’s main character ever since the pilot episode, the show is naturally leaning into quite a bit of nostalgia.

A lot of this came from the conversation between Rick and Daryl when they were trapped in the pit together. Daryl justifies what Maggie’s going to do to Negan by referencing the invaluable things Glenn did for the group. He mentions how Rick was only alive because of Glenn and that it was Glenn who brought Rick to his family and the group in the first place.

Daryl’s words triggered memories of the show’s first episodes where Rick first heard Glenn’s voice inside the tank and when they walked through the streets of Atlanta covered in zombie guts.

The full-circle nostalgia didn’t end there as Rick rode a horse in his attempt to lead the zombie herds away from camp, bringing to mind when he rode into Atlanta in the pilot episode decked out with full Sheriff gear. There will be plenty more of Rick riding a horse in his final episode, a parallel that’s being drawn attention to even in the episode promo.

Episode 4 offered Rick final conversations and closure with some of the closest and longtime figures in his life like Carol, Eugene and Daryl. His last episode looks to spend much of the time in hallucinations of his as he’s bleeding out. This will provide him with the opportunity to have closure with those closest to him who he hasn’t had those final conversations with yet like Michonne and Maggie even if he doesn’t get a chance to see them again in reality.

It will also give him the chance to find peace with those no longer among the living. This includes Shane, who in the promo he’s definitely talking with in the cop car, not to mention that Jon Bernthal was confirmed to be returning to the show this season. The mere presence of characters like Shane will bring back lots of nostalgia for the show’s earlier days, as will the content of Rick’s conversations with these characters.

For those that have watched The Walking Dead from the very beginning and still tune in every week, the end of Rick Grimes is a bittersweet event, one that will be commemorated with plenty of nostalgia.
