In tonight’s return of “The Walking Dead” (AMC, 9 p.m.) all that becomes more gruesomely clear as they try to fight their way out. And while it makes the drama seem like it’s turned to human vs. human with nary a zombie in sight, suddenly there’s a deluge requiring all manner of blows to the skull. The good news is that the action, after slowing to a lull every time the troupe stops to regroup, at a farm and then a prison, is on the move again and there’s a stated secret about what started the zombie takeover in the first place and what can stop it.
