In this case, it was Jon's Dad, but it didn't matter much. Because Jon, now with the mind of a ten year old, couldn't pay too much attention to one subject and, since she was playing with her new set of dolls, forgot about the stone for a while.
Two days later, Jon got out her dolls and arranged them in order on the floor, standing next to her bed, when a thought came to her. She had a magic rock! That's right, a magic rock. Maybe she should try to use it again.
But before she could reach the rock, the two days were up. Things were back to normal... sort of.
