Our preview of the hit zombie show from this year's Comic-Con

The Ricktatorship is officially over. After dealing with the death of his wife and the birth of his daughter, Andrew Lincoln’s character will not be the one calling the shots when The Walking Dead returns for its fourth season in October. ”We’re coming into this season seeing a very different Rick Grimes,” says exec producer Robert Kirkman. ”He is definitely going to be pulling back from his leadership position.” But a leader will be needed, with a new threat looming for the survivors at the prison, including Daryl (Norman Reedus) and Glenn (Steven Yeun). ”There’s going to be some very dangerous elements that are thrown into the mix,” says Kirkman, ”and it’s one more thing that these people have to deal with.” Can a show that killed off four major characters last season continue to say goodbye to so many familiar faces? ”Nothing’s changed,” says Kirkman. ”These characters are living in an environment where if they weren’t dying, it would be unrealistic. Death is always going to be a huge part of this show, and season 4 is going to be no different.”
