John would never admit it, but when the Perks girl caught on that he HADN'T peed in the snow, he had a bit more fun running around and making more snowballs. Of course, the rainbow color didn't exactly look good on him, he only hoped it would wash off later.
This time, he did put a tracking charm on the snowballs, and charmed one to leave a bit of a green and silver tint on whichever girl it hit for a few hours. It would come off with a finite but he doubted either would try that to get it off.
He smirked as he sent it soaring, looking quite like an evil child as he did. He rarely out and out smiled when he was having fun.
