Season 4, episode 04
IndifferenceIn the prison, Rick walks through one of the cell blocks and stops when he gets to Karen's former cell. Thinking about Carol's revelation in the previous episode, Rick imagines Carol stabbing Karen in the head and dragging her body out to the courtyard. Elsewhere, Karen is telling Lizzie not to be afraid of what will happen in the quarantine zone, and to stay strong. Outside, Rick walks to his vehicle and opens his trunk, only to have his suspicions confirmed when he discovers one of his knives is missing.Elsewhere, the supply run group is taking a breather after escaping from the massive horde. As Tyreese washes his shirt, he refuses to listen to Michonne's request to hurry up. The group continues moving towards the veterinary hospital, and comes across an auto shop covered with ivy. The group finds a minivan with a dead battery and begins to clear the overgrowth to get at the shop. While the others carefully clear the brush, uncertain what lies beneath it, Tyreese angrily cuts at the vines, still angered over Karen's death. Suddenly, a walker caught in the ivy lunges at him, and he refuses to kill it until Michonne kills it.Inside the autoshop, the group finds the parts needed to get the vehicle up and running. As they get the required part and hook it up to the vehicle, Michonne realizes that Tyreese is near-suicidal over what happened. She tells him that it's not his fault, and that if anyone has a reason to be angry, it's her over what the Governor did. Bob discloses his alcoholism and guilt over Zach's death to Daryl, but Daryl rejects the idea that Bob was responsible.Rick and Carol set out from the prison on a supply run of their own, and stop in a small town. As they look for supplies and clear houses, they discover a still-living couple hiding in the bathroom of a house. Initially wary, Rick questions the duo, Sam and Ana, while Carol think they might be useful helpers at the prison. Rick reluctantly tells the pair they can come along with them after they finish their search.The supply run group finally makes it to the veterinary hospital, and begins to secure the needed supplies for the infected civilians. Meanwhile, Bob discovers a bottle of alcohol and surreptitiously stashes it in his bag. However, after securing the supplies, the group is attached by a horde of walkers. They barely make it out of the hospital and onto an isolated walkway, but not before Bob nearly loses his bag. When he recovers it, Daryl sees the alcohol and goes off on the medic, saying they shouldn't have picked him up in the first place. They set off back towards the prison.In the town, Rick and Carol are picking fruit when they hear sounds a few feet away. They investigate, only to discover walkers devouring what is left of Ana's body. A short while later, the pair wait at the assigned spot for Sam, but he doesn't show up.Rick finally confronts Carol with the issue of the burned bodies, and tells her that he won't allow her to go back to the prison, for fear that Tyreese will either kill her or the group will shun her for what she did. He gives her supplies and a working vehicle, and they set off their separate ways, with Rick driving back to the prison alone...
