After last week's shocking ending, the second episode of season 3, 'Sick,' starts right off where the other episode ended. Rick manages to sort out the ignorant and potentially dangerous prisoners that were holed up in the cafeteria, and they take Hershal back to the rest of the group in a hope of saving him. But things aren't as smooth as they would have hoped, as the prisoners, especially the lead one, seems to not agree with Rick's decisions, and prove to be a threat to keep around.
This was a great episode of The Walking Dead for a number of reasons, first and foremost the character development of Rick, who is becoming more and more of a morally grey character then before. He makes decisions that we may or may not agree with, but in the end he's always looking out for the well-being of the group. Secondly, the pacing of this episode was as good as the season 3 premier, with intense action and moments to breathe being balanced well. Andrea and Michonne weren't in this episode at all, but the promo for next week's episode seems to feature only them, which is a good sign.
A well paced and exciting episode of The Walking Dead. 8 out of 10.
