Editing/contitnuity error. In the scene where Gabriel is throwing darts at 'Nick', He says that he has been trying to hit Nick, then throws a dart into Nicks lower chest, then throws one into Nicks left shoulder. The camera then cuts to behind Nick and we see the flights (feathers) of a third dart sticking out of the back of Nick like he had leaned forward and Gabriel stuck one in his back shoulder. They only showed Gabriel throwing two darts.

Later back in the hotel room, Ashley lifts Nicks shirt and there are multiple dart pricks in his abdomen.
