The stone glowed immediately, causing Jon to look away momentarily, just as usual. And when he looked back, he grabbed for the stone. He was easily able to move it. He smiled. He was gonna have a lot of fun with this. Just imagine all the mischief he could cause. Nothing harmful, of course. But he was already thinking of people he'd like to embarrass. Like Sarah McMillan and her boyfriend Biff Meadows, for instance. Or any of Sarah's and Biff's friends.
Jon put the stone down and left his room, making sure to close the door this time. And in no time at all (no pun intended), he was out of the house and searching for his first "victim".
