The world of The Walking Dead is about to expand.
Following the shooting of Carl (Chandler Riggs) at the close of the Season 2 premiere, Rick (Andrew Lincoln) will frantically set out in search for help. He'll seek solace at the farm of Hershel Greene (Scott Wilson), which houses a family unaware of just how far the zombie apocalypse has spread.
"They think this is just a temporary thing," explains Lauren Cohan, whose character, Maggie Greene, will be introduced in Sunday's episode. "They've been really sheltered. So when the group comes, they come with all of their energy and all of their news, and I think it takes the Greene family a minute to get their head around what the outside has really become."
