The last time we saw The Walking Dead it was lying in a pool of blood, waiting to rise again as some sort of brain-hungry second season. The bastard game hadn’t so much jerked the tears from my eyes as attached wild horses to the ducts and had the muscular beasts run toward the horizon for a couple of hours. It’s still not clear precisely how the two seasons will be connected but the announcement of 400 Days, a new episode that will act as a bridge between the two seasons, will surely provide some answers. That’s what bridges do. There are probably some clues in the trailer below, which contains at least one character who has appeared previously.
