The stone was dangerous. Jon had decided that much, but in the right hands it could be a force for good. He first had to get Karyn out of her hole however but he couldn't think of a good wish.
"I wish I knew how to reverse Karyn's wish," he muttered absentmindedly, but he got his answer from the stone.
WISH YOURSELF BACK INTO THE REALITY WHERE KARYN HAS RED HAIR AND SMALLER BOOBS
"huh?" Jon thought, "I wish I knew what that meant," he said.
IN ORDER TO MAKE IT THAT A WISH HAS ALWAYS BEEN THE STONE CREATES A PARALLEL REALITY WITH THAT ONE CHANGE WITHIN IT AND TRANSPORTS THOSE WITHIN EARSHOT TO THAT REALITY
Interesting. Jon rushed to Karyn's house, he wasn't going to find himself transported to any parallel reality without her.
