"That's when you shoot them in the leg," Kate guesses, although she's pretty sure that's not the right answer either. She doesn't understand the point of even having the gun if she's not allowed to shoot it and she's about to ask, but then she peeks around the corner of the room and there's Danny.

"Holy shit," she says, surprised, then raises the water gun, keeping herself still half hidden behind the door. "Freeze!"

And to Hermione, she hisses, "Stay there. I found him." If she's not supposed to get shot with the water gun, she's fairly certain that if she gets Hermione shot, she's lost the whole game and they'll have to start over again.
