Jon Is Karyn

Jon shut his eyes, because of the bright light eminating from the stone. And when he opened them, he was in Karyn's bedroom. "Karyn! I'm going to the store. I'll be back soon," yelled Karyn's mom. Jon opened his door. "Uh. Okay, Mom. Uh ... Jon will be coming over." "Who?" she asked. "My friend, Jon." "Is that your new boyfriend? I really can't keep track of them all." Jon thought that Karyn would have *his* life, but apparently the wish made it so that he didn't even exist at all. So what happened to Karyn? Was she totally gone?
