There's trouble afoot for The Walking Dead's prison community. A deadly virus has swept through the group, leaving death and walkers in its wake. Karen and David were brutally burnt alive by somebody and the undead gathering at the perimeter fences are being fed rodents by someone from within the group. How much longer will they be able to stay at their gated community before the walls come tumbling down?
Showrunner spoke to The Hollywood Reporter about how much longer the survivors can remain at the prison:
We've shown from the beginning that they have to do this regular maintenance on those fences -- meaning taking out walkers at fences. They're a little busy right now, and they're not at full strength but they need to be. They have a big problem coming up. We've talked about different locations this season, so who knows what can happen. Who knows, maybe they'll pull it off and maybe that requires another location. Maybe other locations come from them not pulling it off. It comes to a head sooner than later.
AMC released a sneak peek clip for Sunday's episode "Isolation" that shows Daryl drive headlong into a horde that contains thousands of brain-hungry walkers. If they reach the prison, there's going to be trouble.
