So Bernaurd was a Host of Arnold that Ford created because he missed his friend. Interesting that Dolores said she killed Arnold. I wonder if Ford had her kill him or if she went haywire. It seems Teddy went crazy and murdered the town. I am wondering if he is really Wyatt and will "wake up" when he gets through the maze. I am pretty sure William is the man in black. It would be interesting to know if he really was raping her those times at the farmhouse or if he took her into the barn and talked to her. He did seem to go pretty dark with killing that whole camp and chopping them up so he just might be a bad guy now. He definitely was a bad guy when he killed the host and her daughter.

My theory is this is actually a sequel to the movie. Hosts killed humans and the park was going to go under until William used his titan of industry muscles to keep the park open. They rebooted every host but Arnold viewed them as his children and buried code deep in their subconcious.
