"Karyn, why did you have to bring your sister along?" Jon asked. It was really Sally inside Jon's body, but thanks to Jon's wish, she acted just like Jon.
"She wanted to come with," Karyn answered.
"Well, I only wanted to use the stone with you," Jon said.
Hey! How does Sally know about the stone? Jon thought to himself, or herself. But then the answer came to him. Jon would know about the stone, so it would be weird or out of place if he didn't talk about it, especially to Karyn.
"You've got a point." She turned to Sally (who was actually Jon). "Sorry, Sally. Maybe some other time."
Well, no way was the fake Jon going to make wishes without him tagging along. Jon willed himself into Karyn's body and Karyn went into Sally's body. And thanks to Jon's wish, Karyn (while in Sally's body) acted like Sally. She pouted and walked back home.
"Come on, Karyn. Let's go."
And Jon, in Karyn's body, went to the park.
