"I don't know what to do with you," said Sarah. "Jon is my friend, even as Paige. But he always hung around you. I never cared about it back when I wasn't friends with Jon, but I do now. I..." She tightened her grip on the stone, though that really wasn't necessary, and prepared to make a wish.
Sarah waited and just when Karyn was sure she was finally going to wish her away, she instead said "I can't do it. I wouldn't hurt Paige like that, by just taking her friends away. We've got to have some way of working this out... I wish Paige was here."
Jon/Paige suddenly opened the door. "Karyn's here?" she said.
"She just got here," replied Satah. "Fast-talked her way past Mom into breaking apart my furniture."
"But I don't see how you could have known ahead of time..."
"It was the stone," explained Sarah. "I wished you were here, and you didn't hear the wish, so you think you came here because I called you. I just made you appear here a second ago. Anyway, we've got a problem."
"Yeah, I can see," replied Paige. "Karyn, what are you doing to Sarah's furniture?"
"Jon, you need to get the stone back from her! Who knows what she's going to do with it?"
"Oh, come on," replied Paige. "We're friends and she'd never hurt anyone like that."
"It's the damned rock! She's such a bitch! She used it on you!"
"Karyn," said Paige. "It's fine. It isn't some sort of mind control, she was trying to be nice. That's why she made the wish. Sarah, can I have the stone back, please?"
"I hope you can talk some sense into her," said Sarah. "I don't see what you see in her anyway."
Taking the stone, Paige made her wish. "I wish," she said, "that Sarah would be friends with Karyn."
Suddenly Karyn (and everyone else) had to look away. "What?" said Karyn.
"You don't have any excuse now," said Paige. "Karyn, Sarah's going to be nice to you, and you have to be nice to her, and not because of the rock but because it's the only decent thing to do now that you know she doesn't hate you."
"I'm sorry about all the trouble," said Sarah. "Let's be friends with each other, all right?"
Karyn grumbled, but she knew she had no choice. Her whole argument was based on Sarah being a bitch. If she wasn't, she didn't have much of an excuse. "Sure," she said.
"But one thing," said Paige. "Karyn, you really need to show you're willing to be friends with us. Maybe you should put that bed together."
"But you have the stone! Just wish for it to be back together."
"The bed," said Paige.
Karyn grudgingly began to reassemble the bed, while Paige and Sarah smiled at each other. "She'll be okay," said Sarah.
"One thing I don't understand, Jon," said Karyn, "is why the stone didn't change my memories of Jon, your clothes at home, or anything else except your body. It usually changes reality to make things happen."
"Hmm," said Paige. "I wish I knew... Ah. It has to do with making a wish that wears off. If the wish changes reality, it can't just wear off, it has to change reality a second time when it wears off. This is something you might not want, so when you make a reversible wish it doesn't change reality unless you ask it to. I wish that reversible wishes now work like other wishes."
"Let me see the stone," said Sarah, and Paige handed it back to her.
"I've been thinking about how to help you, Paige, and I think I figured something out. First of all, I wish that until you change back after the prom, reality changes so you were always Paige and only our friends remember you as Jon. Now, the wish..."
"How do you know about making wishes?" wondered Karyn.
"I don't," said Sarah. "No more than any of us do. It's something we have to figure out for ourselves."
Of course, Karyn never did really know Sarah. There was no reason Sarah couldn't be smart enough to reverse wishes. Just because she hated Star Trek and had blonde hair didn't make her an idiot.
"I wish," said Sarah, "that the wish for Jon to have designer clothes means that when he's a guy he'll have guys' designer clothes. I wish that the wish for perfect makeup means makeup perfect for whatever his form is, so if the perfect makeup is no makeup, he has no makeup. I wish the same for the manicures and pedicures."
"Thanks," said Paige and hugged Sarah. "I feel much better."
"Anything for one of us," said Sarah. "I wish that me and my best friends could summon the stone at will at any time but the one who had it before would know where it went. I think that's it..."
"Yeah, I suppose" said Karyn. "So, umm, Jon, I mean Paige... you're thinking like a girl up until the prom, right?"
"Right! I don't want to be miserable being a girl, after all. I'm glad Sarah made that wish."
"Well, about that, I've been meaning to ask you..."
