With all due respect
@63dot you seem overly focused on Terrence Howard. I think his character is truly gone. I could be wrong, but big actors have been known to take smaller parts just because they wanted to be a part of a project. Do you have any firm evidence that he will be in future episodes and not in the form of a flashback as we have seen thus far this season?
I may be taking him too much into account, but Sheriff Pope, whoever plays him, is the main villain in all three books.
You have Pilcher, the villain in a sense, who still wants the best for the town but may not know how to carry that out. The first town, who was told the truth, turned into a disaster so he's trying everything. The nurse, his sister, started out as the bad character (next to the sheriff) but she's taken a softer side, first since Ethan was rescued with the helicopter, and then as an advocate for the security watchers behind the scenes offering herself up to be punished instead.
Pope was one truly twisted character who seemed to get joy in being a dictator so who is there to root against? It's just that someone who read the books mentioned he's in all three on this thread.
If screenwriters have changed this and written Pope out of first book in three books, then they could make the teacher the main bad character but she would have to gain full power or be the evil behind Pilcher, the nurse, and Pope which I find unlikely. She's just a player in all of this and trying to support Pilcher.
Any thoughts of having Kate Hewson or Harold Ballinger be the main villain is not plausible since they are trying to escape (not knowing about abbies).
And maybe there's an abbie running everything, or maybe one of the humans shape shifts (like in the TV show "V") from human to abbie and is the main bad guy.
Lastly, though I don't see how, the kids could be running the show and the adults are just secondary in Wayward Pines.
I have resisted reading any short synopsis of the three books so I really don't know who is the bad guy, and I am having a hard time trying to figure out who the hero is, if there is even a good guy. If there are not clear good guys, then it's kind of spicy in a "L.A. Confidential" way.
