Though Joe desperately wanted to get to know Melissa better, the fact that the medallion had stopped working was still nagging in his mind. He quickly developed a plan for an additional test. First, he called up his good friend, Zach. Zach was flabbergasted. He couldn't believe Melissa was calling him and asking him to come over to her house--Joe decided it was best (for now) to not reveal who he really was. As Joe waited for Zach, he started talking with Melissa's younger sister, Patricia. She was only about a year younger than Melissa, and after a short discussion, Joe knew he wouldn't need to call another one of his friends. When Zach arrived, Joe used the medallion to switch Patricia and Zach. Both had been curious about what it would be like to be someone else, so they weren't exactly upset...but they certainly were shocked. However, when Joe tried to switch them back, he found that the medallion (once again) wouldn't do so. Joe became a little worried--what if it only worked once per person? Patricia didn't seem so concerned, and quickly made her way back to Zach's house, eager to explore her new body in private. Meanwhile, Joe and Zach (in the bodies of the two sisters) had to admit they had some curiosity of their own.
