6. Indifference (Episode 4)
This is one of those episodes that is pretty close to qualifying as a bottle episode (no pun intended, Bob Stookey). The episode centres around only two groups: Rick and Carol's supply run which they embark upon during this episode, and the run to the veterinary college with Daryl, Michonne, Tyreese and Bob Stookey, which began in the episode prior. Aside from these two plot threads, we meet two new characters by the names of Sam and Ana. There is, however, some solid Carol development here, as well as some interesting storylines resolving with the sudden disappearance of Carol for something that could have easily been discussed more politely. One reason this otherwise decent small episode is so low on the list compared to, say, Clear (another bottle episode) is because we've pretty much seen this storyline in the first episode with Clara. Speaking of which...
