A family hour that revolves around Merle and Daryl may not be 7th Heaven material, but its a family hour nonetheless. In Walking Dead style, the episode takes us to a comfortable spot where characters bond, rest and enjoy home, before it rips the spot right under Carol's nose in the form of gun fire. The Governor is back! Threatening eveything Michonne holds dear, he is testing their time response with an assault full of walkers.
It's up to the man who was going to robb Carol's camp before season 1 was over, to protect them from a Governor that swears would destroy the prison before this show is over.
