This past Sunday's all-new 'The Walking Dead' episode "Home" put our heroes in a tricky spot, as Woodbury's Governor launched his first attack on the prison as a warning of even greater horrors to come. Now, as the remaining survivors plot out their next move, has the prison already come under siege from another force? Check out the latest photos from Sunday's upcoming episode "I Ain't A Judas" to see 'The Walking Dead's next big battle!

Life for 'The Walking Dead' survivors of AMC has very few moments of peace, but it seems things are already back to hell by the time the acclaimed horror-drama returns this Sunday with "I Ain't A Judas." Following the events of the previous episode's battle, which left a number of walkers shambling about the facility, the remaining survivors will band together with the returning Dixon brothers to take on what looks to be a new threat to the group.

Could the Governor have returned already to exact new vengeance? Might an old friend be arriving at the gates of the prison? Or is Rick leading everyone on a wild goose chase after his recent breakdowns?
