Jon thought. Should he have explained the stone to David? They had been going out for over six months. But telling someone about the stone was a big thing. He hadn't even told his parents yet, or his relatives, let alone his significant other.
Meanwhile, Sarah approached.
Fortunately, or perhaps unfortunately, Jon was changed back to a boy out of earshot of her. So she remembered Jon being a boy. In the reality where Jon was a boy, David wasn't hitting on Jennifer, so Sarah had no reason to transform David. So she didn't remember transforming David. But she still knew about the stone, and still wanted it.
"Let me see your magic stone!" said Sarah.
"What magic stone?" replied Jon.
"The one you're holding in your hand," said Sarah. "The one which gives people free Pepsi."
Jon, pretending not to have heard it, looked at his boy/girlfriend. "Free Pepsi stone? Do you know what she's talking about? You'd think she was a bimbo or something." Sarah wasn't one any more, of course, but talking about a magic stone isn't a good way to appear to be a mental giant.
"I'm clueless," said David.
"Me, too," said Jon.
"Come on now," said Sarah. "You... Oh, never mind. You're right. It does sound a little silly, doesn't it?" She giggled nervously, tried to seem apologetic, and approached Jon. "I don't know what came over me. Maybe I was half asleep or something and I imagined...."
Sarah was only ten steps away from Jon. It would have worked, too. Jon believed Sarah was confused and would have let her get close enough to make a grab for the stone... except that at around the fifth step, David raised his/her arm in Sarah's way and said "We don't want you here. I assume you mean that rock Jon's holding. I don't know what it is, but I trust him with it more than you."
"Bitch," said Sarah and tried to force her way past David.
"Bitch," replied David unoriginally.
"Half-bitch," replied Sarah.
David shoved Sarah back, keeping her away from Jon. It wasn't that strong a push, really, but it was enough to work in a catfight.
"That's cheating," said Sarah, despite the lightness of the push. "You couldn't do that if you were a girl!"
"David's enough of a girl for me," said Jon. "Now I wish you'd forget the stone... and this wish too." Pausing just enough to let the wish finish and look away, Jon then added "Why are you fighting?"
"Because your boyfriend or girlfriend or whatever said... What did they say? I don't know." Sarah wasn't able to finish the thought. "Oh, geez." She turned and started to walk away.
Jon yelled at her "I promise, no bimbo jokes based on that."
"I can't believe the nerve of her..." said David.
"Forget it," said Jon. "Let's go do something else." Jon pointed some distance down the beach and said "I think I see the ice cream-selling guy down there. Maybe we can go get a popsicle or something."
