 CONT: When Tripp is showing Paula how to shoot the paintball marker,  he is clearly rolling the trigger and the marker is not shooting so  apparently it isnt on. But when Paula gets the marker in the next  shot she shoots Ace in the foot. The marker is electric and you have  to cut it on to shoot it. You couldnt see either one of them  cutting the marker on so Paula shooting the marker would have  actually been impossible without cutting it on.
