The Walking Dead: Recap of Episode 4.04 - Indifference
The two people, Sam and Ana, were in the greenhouse nearby that had fruit before they were chased here by the walkers. When Sam complained about his dislocated shoulder, Carol took the reins to reset his shoulder. Rick observed from the back and was impressed by Carol's taking charge.
Daryl and Bob found a car battery while Tyreese and Michonne continue to clear the fallen tree from the car. Michonne lectured him about anger. "Anger makes you stupid." She was angry about the Governor but not any longer, although she still couldn't explain why she kept going after him.
While Rick and Carol were cleaning up the house of food and medicine, Sam and Ana wanted to join them back at the prison. They wanted to help and Carol suggested they scope out the neighborhood for more supplies even though while Rick was apprehensive about it, he finally agreed.
Watching Daryl fixing the car, Bob confessed his guilt about causing the accident at the Big Spot supermarket when Zack got killed. He had a drinking problem and tried to stop himself with the bottle when the shelf came down, causing the mayhem. After getting the car to start, Daryl then told Bob that what happened at the supermarket was an accident and wasn't anyone's fault.
Raiding another house's medicine cabinet, Rick asked Carol if they did the right thing to let Sam and Ana join them. Carol was hopeful about them. Then Carol confronted Rick to talk about what she did. While Rick was more driven by morals, Carol was more pragmatic. "You don't have to like what I did, Rick, I don't. You just accept it." Wow, Melissa McBride is killing it this episode as Carol!
Daryl and the group got to the veterinarian school and started their search inside.
