'The Walking Dead' Season 4: Where Will Things Go After The Prison And Governor?

"I don't want to give anything away because we have some really cool stuff planned for the finale, but I will say that there is a resolution to the storyline at the end of the season, as people would expect," Robert Kirkman told EW. "It becomes a whole complete story that you’ve been able to experience over the course of Season 3. And It will set things up nicely for Season 4."

Will they abandon the prison at the end of Season 3? The comic series, which Kirkman co-created, featured the Governor attacking the prison crew, driving them from their safe haven. The main characters split up, reconvening at Herschel's farm before being greeted by new characters who take them on a journey to Washington before settling in a new community ... and eventually coming in contact with more deadly and dastardly humans far more dangerous than the zombies.

"There are new places to go in Season 4, but whether or not that means a new setting or new story direction or simply new characters I can’t really nail down any specifics," Kirkman said.

However, executive producer Gale Anne Hurd said the zombie threat will not go away in Season 4. "We are going to amp up the threat of the walkers, because they've started to seem like a manageable threat. They are not a manageable threat," she said during "The Walking Dead" PaleyFest event. "But, it is the people who you think you can trust who betray you, that you have to fear. It is the monster inside you. We all have them. How do we keep them in check?"

Kirkman did tease there will be at least one and possibly more deaths at the end of Season 3
. "I'm afraid there may be a casualty or more still to be experienced by the end of this season," he said. "We’ll see."
