"Jon, you know the other bunk belongs to your girlfriend," Zoe said.
"My girlfriend ... ah, never mind." Something funny was going on. Jon didn't have a girlfriend. Karyn was close, but she was just really a friend. And even if he did have a girlfriend, how could he ever talk her into sharing his bedroom with him? The room looked mostly the same ... was it possible that someone else had really lived there? Would he open the closet to find her clothes and things inside?
Quickly, he ran into the room, shut the door, and looked around. It did look as though someone else had lived there as well as Jon. But there was no mysteriously appearing second person there.
Jon sat down. Got to find out, he thought. Maybe the stone would know.
"I wish to know who my girlfriend is and why she shares my bedroom with me." The stone glowed, granting his wish and giving him his answer.
