Plot hole: When the teens in this film come to camp, they see in the bathroom a sign spray-painted by one of the kids from Part 2 that says "Fuck Angela Baker." This doesn't make sense because in the second film everyone only knew her as Angela Johnson. So the sign should have said "Fuck Angela Johnson."
