"Who are you?" Jon asked.
The person who now had Sarah's body turned and said "Karyn. Karyn Black."
"Oh thank god, it's you," Jon said.
Karyn (in Sarah's body) turned towards him. For the first time, she really looked at him. "Biff? What am I doing here? Did you ..."
"Karyn, relax. It's me. Jon."
"Jon?"
"I used the wishing stone last night and accidentally made a vague wish for something interesting to happen. This must have been the result."
"So, what is this? A body swap?" she asked, looking down at Sarah's body. She was wearing a lacy nightgown.
"More like a mind swap," Jon said, getting out of bed. He looked down at Biff's naked body. "Oh man." He grabbed the nearest article of clothing he could find (a T-shirt) and wrapped it around his waist. "Sorry, I didn't notice I was naked. I mean, that Biff was naked."
Karyn laughed. She heard Sarah's laugh instead and suddenly stopped. She couldn't believe that of all the people she could swap with, she had to swap with that bitch Sarah McMillan, who had constantly picked on people like Jon and Karyn. People that Sarah deemed "inferior". She remembered Sarah using that same exact laugh when she was mocking people.
"Do you think this is just a straight swap?" Karyn asked.
"What do you mean?"
"I mean, was there just a swap between me and Sarah? Or did more than two people get exchanged? Like me, Sarah, and someone else?"
"I have no way to know."
"Why don't you just make a wish?" Karyn asked.
"I don't have the stone. It's still in my bedroom. This is Biff's bedroom, remember?"
"Oh, yeah."
"We'll have to go to my house," Jon said. "I wonder who has my body."
"And mine. Boy, I hope that bitch doesn't have it."
