With 3 different collectors covers featuring Rick, a much older-looking Carl, Daryl and his bad-ass chopper, it's very apparent that the prison still has no running water. Showrunner Scott M. Gimple recently teased about a potential new threat facing our heroes in season 4;
“The new threat is something you can’t just stab in the face,” Gimple says. “You can’t talk sense to it. You can’t make a truce with it. It’s beyond all that. It would be a threat in any world, but in this world it is much more terrifying.”
Look for season 4 to premiere way too far away this October!
