The Walking Dead generally uses each half-season to tell a single story. They’re obviously not entirely standalone installments, and there are larger things that play out over more time, but each section definitely has its own distinct arc. Showrunner Scott Gimple has talked about this strategy quite a bit, and it’s served them well, as every time the show comes back from an extended break, like the current midseason hiatus, you start anew in many ways, keeping things fresh. This latest instance is no exception, and when the zombie drama returns for the rest of season 5 this weekend, expect some big changes.
There may be some spoilers beyond this point if you’re not caught up, then again, if you’re not current, why do you want to know what happens next?
