If you didn't watch last night's episode of The Walking Dead, "Infected", be warned that there are spoilers throughout the rest of this story. AMC has released three trailers for next week's episode "Isolation", airing Sunday, October 27 at 9 PM ET. The group is still struggling with a new sickness that is spreading rapidly throughout the prison. When things couldn't look much worse, Darryl (Norman Reedus) Michonne (Danai Gurira), Bob Stookey (Larry Gilliard Jr.) and Tyrese (Chad Coleman) make a shocking discovery while out on a supply run. In addition to the trailers, the network has debuted two behind-the-scenes looks at "Infected", along with last night's most talked-about scene, and never-before-seen photos from both episodes.
