Last we left our heroes of Alexandria, things were going to zombie hell. And if the undead weren’t the problem, other people were. In the first four minutes of the mid-season premiere of The Walking Dead, we rejoin the field team consisting of Daryl, Sasha, and Abraham as they run into a checkpoint, courtesy of Negan. While we don’t get to see the biggest bad of the comic books (and in fact, we won’t actually see Jeffrey Dean Morgan get his evil on until the season finale), his name is invoked from the jump. “Who’s Negan?” is probably a question Rick Grimes & Co. will be asking for the rest of the season, but it’s an answer they probably won’t want to know.
