"Jon?" replied Joy. "You called me Jon. You remember me?"
"Yeah," said Alison. "I remember you, of course."
"How is that possible?" asked Joy.
"What do you mean how is that possible?" replied Alison. "Me and you were trying to get the magic stone back from Karyn. We got dressed up as girls... I can't remember why. I think Karyn may have hexed us. She made this wish about the first of us taking off our clothes transforming into masculine girls and we both took our clothes off and half-transformed. Jon into Joy, me, Aaron, into Alison."
"That wasn't you, it was me!" said Alan.
"Wait a minute," said Joy. "Your name is Aaron?"
"No, it's Alison now. I'm Alan's sister. And I feel like a teenage girl now. I ought to use the dream machine to look more like one... I just came in here wondering if you're done with it and I can use it."
"I get it," said Joy. "When I moved Alan's memories into a male clone and made you into his sister, the reality is that you recently became his sister by being a part of all this. So you know my old name. And the wish that forces us to use the names makes us call you Alison and me Joy, but it doesn't make you do anything and we can call Alan Alan again.""
"New person?" replied the new Alison, who thought she had been Aaron. "What? That doesn't make any sense."
"Never mind," said Joy. She looked around and picked up the machine, then turned it on. "Hmm," she said. "I don't need to change this." Joy and Alan moved closer to look and saw that Alison's fantasy was becoming a normal girl. She handed it to Alison, who pointed it at herself, activated it, and a purple glow filled the room... and Alison turned into a normal girl, then said "Why am I holding this?" and dropped it.
"Watch out! That's dangerous," said Alan. He picked up the device, and accidentally hit the activate word by the nightmare... while it was pointing at Jon.
He read off the nightmare. "Joy becomes pregnant...."
