Karyn took a guess. "You have cheerleader's outfits. Jon has just turned into a girl. So you probably want Jon to join, right?"
"What" replied Sarah. "How's that a puzzle? Didn't you ask me? I wasn't going to refuse. Even if Amber is only a girl as long as she's sick."
"But I didn't ask--" Or did she? Was it all a part of changing reality? Just having long hair and breasts like Sarah could mean that Karyn was now supposed to be Sarah's friend. But just that all by itself shouldn't mean that Sarah suddenly had memories of Jon wanting to be a cheerleader. Which means that Mikey probably did it. If he didn't do worse. Let me guess again, we're going over to Amber's place to give her the uniforms in person, right?"
Karyn knocked on Jon's door. Jon, or rather, Amber, answered and opened the door. She stared at the uniforms.
"She agreed to let you join the team," said Karyn.
"I didn't know what size you needed," said Sarah. You'll have to try both sizes on."
"But I didn't--"
"Remember, when you did?" said Karyn? "Unless someone made a wish and it rewrote reality, you certainly asked Sarah to become a cheerleader."
"I did?" said Amber. "I guess I did. Could you please leave the uniforms here? I need to talk to Karyn about something. I guarantee you I'll figure out which one is the better size."
"You're acting weird, Amber. Are you sure you're feeling okay?" asked Sarah.
"No, because I have a disease," replied Jon.
"You ought to say 'thanks'."
Amber grumbled. "Thank you, Sarah."
"Well, that's what you get for making diseases," said Karyn.
Amber shook her head. "No, Karyn. That's not what I did. Maybe you didn't follow what happened, but what happened is that Mikey made the wish. When he wished that the wishes were on me instead of Tommy he had already made it a disease. I just figured out that it was a disease. Wishes change reality. Since I remembered being Jon, the reality must have been that something changed me recently. Then I asked the stone if it was a disease and it said yes. I didn't make it a disease. All I did was change who had the disease so Mikey and Tommy caught it too."
"I guess I didn't understand that last time you explained it."
"Now, about Sarah. Mikey's coin gives three wishes every twelve hours. He used one to make Mom call me Amber and another to make me a cheerleader. There's a lot worse that he could do. I wish that nobody can use the coin to get the stone, to twist any stone wishes, or to force any stone wishes."
Nothing happened. No flash, no eye irritation.
"What? Did Mikey prevent that? I wish I knew what's going on." (Flash) "Hmm, never mind."
"So what did the stone tell you?"
"Before Grandpa gave us the stone and the coin, he made sure we couldn't use them to interfere with each other. Which is good because I got what I wanted anyway--Mikey can't use the coin to steal the stone, force me to twist a wish, stuff like that. But it's also bad because I can't do it to him either. I can't force him to use the coin nicely, I can't steal the coin, I can't make him unable to say the word 'wish', and so on. We can't cheat, either, like, I can't turn him into a tree and prevent him from using the coin because trees can't talk. That's why the best he could do to me was my name and the cheerleading."
"What are you going to do about that, though?"
"I don't know. The disease can't last that long. And it takes a while to learn something like cheerleading, so how much time would there be for me to do it?"
"You never did say how long the disease lasted, Amber...."
