A couple of things that I don't understand (spoilers)
1. Why/how did the cops end up finding the victims that Carleton captured once he reverted back to Captain Howdy? It seemed really random based on the way it was presented.
2. How did Mike know where Carleton was hiding out at the end of the movie? He just walks into some random church and calls him out. How did he even know he was there? They didn't seem to show how Mike discovered Carleton was hiding there.
