Kelly only continued to smirk and left the room. Before she closed the door, she said, offhandedly, "I'll only tell you that you won't be able to do anything about it." The door clicked shut as she ducked out of the room.
Jon sat on his bed, wondering what he would do. If only he had the stone...
Suddenly the door popped open and Kelly came back into the room. "Oh, I decided that I'll let you have this back for now..." She tossed the stone onto Jon's bed. "IF you can prove you're trustworthy, I'll let you keep it." She turned her back on him and started to leave again.
However, before she had reached the door, Jon shouted from behind her, "I WISH THAT KELLY-" but was cut short when the stone glowed brightly and vanished from his hand. Jon looked around for the stone, wondering where it had gone. He heard Kelly giggling from the door.
"Looking for this, brother dear?" She held the stone in her hand. "I warned you. Now I'll be keeping this for now. You'll get punishment for what you just tried to do to me later." She left the room, howling with laughter.
