Now since Jon was gone and she was by herself, Karyn finally realized something. The bedroom she was in wasn't Jon's bedroom. Well, it was his bedroom (same furniture, same possessions), but it was clearly part of a different house.
She left the bedroom and immediately noticed that it was her house. But the room that was Jon's bedroom didn't exist in her original house. The stone must have added it to give Jon a place to live, since he was in no way related to his original family now.
Thinking about family, Karyn had a sudden thought. If she was Jon's mother, then who was Jon's father?
Holding the stone, she decided to find out. "I wish to know who Jon's father is." The stone glowed, granting her wish.
