Karyn closed her eyes for a few moments and when she opened them, nothing happened. She shook her head "no".
Jon felt a little relieved. As long as no one talked, he'd be safe. But he still needed to know why his wish to return to normal didn't work. Was it because he couldn't reverse wishes or was it because he couldn't make wishes period?
There was an easy way to find out.
"I wish that only for the next two minutes Karyn would become a boy named Kevin." If Jon could still make wishes, then at least this wish had a time limit. And if he couldn't make wishes, then it just wouldn't work.
Karyn's eyes went wide, wondering why Jon was making that wish.
