"I wish that Karl and I were hidden from the evil Sarah that night because Evil Sarah had a lapse of memory about where her house is, not because we changed into other people."
They transformed... transformed back, in fact. Karyn was now Karl. Jon was now Sarah, or rather, Good Sarah, but since she had heard the wish, she kept her Jon memories.
"So what movie do you want to watch?" asked Sarah.
"Not sure. Hey, we time travelled, why not Back to the Future? The time paradoxes in that are really strange. We... oh, man."
"Karl? What is it?"
"The time paradoxes. I didn't think about it, but I should have."
"What do you mean?"
"Do you remember what the names of your parents are?"
"As Sarah? Rachel and..."
"No. Rachel's her middle name, just like yours."
"Mom's name's the same as me. I was named after her. I'm Sarah Rachel McMillan II, she's Sarah Rachel McMillan."
"And your dad's name, Sarah?"
"Karl McMillan... wait a minute. Karl, like you. You don't mean..."
"Yeah. Your mom and dad are named Karl and Sarah. They're rich people who were living in the McMillan mansion since before you were born. We're named Karl and Sarah, and we wished ourselves to be rich, and this is the McMillan mansion, and we're now in the past, before you were born. This sort of thing only happens in sci-fi and with magic stones."
"So I'm my own mother?"
"Something like that. We don't time travel back home using the stone. We just wait. By that time, we'll have a daughter named Sarah, who'll look just like you did at her age. She'll get split into two, and one will vanish into the past, leaving one behind. She's evil, but I bet we can wish our way around that. We could even change things a little, just as long as somewhere in there we still go to the past and keep the cycle going."
"What a mess," said Sarah.
