The Walking Dead returned to AMC last night, with the Season 4 premiere "30 Days Without an Accident". Today, the cable network has released three sneak peeks at next week's episode, "Infected", airing Sunday, October 20 at 9 PM ET. As you can likely tell from the episode title, a strange infection is spreading throughout the prison, and we can see how much chaos it causes for Rick (Andrew Lincoln) and the rest of his group. In addition, AMC has released two featurettes that take fans behind-the-scenes of "30 Days Without an Accident", along with 10 photos from last night's episode.
