Joy thought about it for a while. "I have an idea," she said. "Sort of."
"Sort of?" replied Alison. "About Karyn or us?"
"Well, we can wish away at least some of Karyn's change, but I was really thinking about us."
"With a 'sort of'," said Alison.
"It's a big 'sort of'," continued Joy. "You see, Karyn wished that we'd become the girls we looked like. Which girls did we look like?"
"Huh? I don't understand."
"Well, think of it this way. If you're disguised as a girl and wearing a blonde wig, you look like a blonde girl. But you also look like a brunette in a wig. We can reinterpret wishes, so we can pick."
"You mean," asked Alison, "that if we're wearing padded bras, you can say 'we look like girls with big breasts' but we can also say 'we look like girls with small breasts in padded bras'?"
"Right! We can change it. I wish that Joy and I would turn into girls that looked just like Jon and Alan, and are wearing feminine disguises like we did as Jon and Alan."
A moment of disorientation, and the wish had come true. There were no weights on Joy's chest, for one thing. Everything was back... almost. They were still girls, after all, just girls that looked exactly like boys.
They went off to the restroom to change their clothes back, and to figure out what to do about Karyn (and their names). Things certainly weren't back to normal yet.
