Photos and a video clip from this Sunday’s The Walking Dead season 4, episode 4 titled “Indifference” show Rick and Carol visiting a new home.

Last Sunday’s The Walking Dead season 4 cliffhanger showed Carol coming clean about the killing and burning of two people when she was confronted by Rick. Her matter-of-fact response told viewers she had no problem doing it, though a conversation with Tyreese earlier in the episode depicted the mother in an emotional state after speaking with him.

In this new clip we see Carol and Rick going inside an abandoned home in search of some medicine. Unsurprisingly, the residence has at least one zombie in it who falls down the staircase towards the two humans. The clip ends as a bedroom door upstairs is opening – is there a human inside? Or just another walker? Watch below:

In a second clip we see Daryl and company running into some zombies during their supply mission.

In addition, two photos from The Walking Dead season 4 show Rick and Carol entering what may be the above home’s compound, and Daryl leading the charge on a mission for medicine as Tyreese consults the map that Hershel drew up in episode 3. The group is in search of medication that will help treat the symptoms that many people at the prison have fallen victim to. If not treated in time, the humans turn into zombies for a reason that still isn’t crystal clear.

The Walking Dead season 4, episode 4 “Indifference” airs this Sunday, November 2 on AMC. The storyline’s synopsis reads, “The supply mission faces hurdles; the situation at the prison worsens.” The trailer for the episode can be viewed below (it debuted a couple days ago):
