"How about this?" suggested Jon. "If there's a good and an evil Sarah and I'm the good one, why not just wish that we're both good? That way we can have Sarah and me at the same time."
"I don't know if that will work. I told you, if we never found the magic items, she shouldn't exist. But she does... maybe the cabinet is as powerful as the stone."
"Or... Wish that I was the evil one and she was the good one."
"If you were the evil one, you'd be where she is now and she'd be Jon. No, that won't work. Hmm... we can go to your place and you can let me use the stone?"

The voice spoke again, this time giving a suggestion.
"I don't know," said Jon. "That isn't exactly what either of us want."
"But it's close," said Karyn.
"We probably should try it," said Jon.
"Okay," replied Karyn. Following the suggestion, she said "I wish...."
