I can't figure out why Andy (I think his name was Andy, the brother that goes with you to the camp) was worried about you seeing the camera.
As soon as you pick it up he asks to see it, which I didn't think much of at first, until he said "Good" when you find out there's no batteries.
I thought there had to be something on that camera involving The St. Johns, but there wasn't. It was just the crazy lady stalking the motel, and getting harassed by bandits. So why would he care?
The only thing I can think of, is maybe the deal with the bandits was a little more than just giving them food. Maybe the bandits were finding people for the St. Johns to cut up, and the crazy lady got away?
