Jon closed his eyes, but not just because the stone was making him do it (because of the flash of light), but also because he didn't want to see what happened. Chad was a menace when it came to making wishes. What was Jon thinking, coming to Chad for advice? The wisest man Jon knew? Yeah, right.
"Hey, it worked," he heard Julie say.
It did? Jon thought. Maybe Chad wasn't as much of a screw-up as Jon thought. He opened his eyes and looked over at himself. His body looked almost the same as it normally was, except ... maybe a little older? Yeah, perhaps twenty or twenty-five? And if his body was that age, then that meant that Kathy's was too. Jon didn't like it that he was still older than he was supposed to be, but it was better than being elderly and decrepit, he supposed.
Now all they had to do was figure out a way to get Jon and Kathy back in their own bodies.
