"Oh my god." Jane said. "It can't be!"
"It can," said Jon, "but... Wait a minute. Why can't the stone change someone who's pregnant? You can wish someone dead. You can even wipe someone out of existence. Why can't you wish away a pregnancy? Mom, tell me exactly what the stone said."
"I don't remember," she said. "It just sent some ideas into my head. It had something to do with pregnancy, I know that."
"I wish," said Jon, "that I know why that wish didn't work, in a lot more detail." Jon clutched her ears and a second later said "Mom, the stone tries to avoid accidents. If you tell it to kill someone, it will. But if you wish for a hundred thousand dollars, it won't kill Grandma and give you the insurance money. It's a nice stone--it figures out another way. Pregnancy is like that--it'll stop a pregnancy if you say so, but if you don't, it tries to find another way."
"Another way? But it didn't do anything."
"It figured out a way without doing anything. You wished my body was male. The stone took that to mean that my original body was male in the past, which is true."
"So all I have to do," said Jane, "is wish you to be male, but say what I want to happen to the pregnancy?"
"Pretty much, but you might want to do something about your pregnancy too."
"Okay, Jon, then I wish...."
