As Jon was taking a shower, something happened. But, he didn't notice it. Or rather, Becky and Jon swapped bodies, and Becky, who wasn't near the stone at the time, didn't notice it. She continued on showering, now believing she really was Jon.
Meanwhile, Sarah wasn't making any more wishes on the stone, because she had to go to school first to see what changed....
Jon (or at least someone who thought he was Jon) finished his shower and got dressed. He picked up his stone before going to school, but fortunately Sarah wasn't making any more wishes.
Jon arrived at the school, with Karyn.
Sarah walked right up to Karyn and asked her, "Well, bleached blonde, who's the most popular girl in the school?"
Karyn didn't know what Sarah was up to, but took a guess and said "Becky Goldson?"
"That bitch!" replied Sarah.
The next person Sarah looked for was Becky. When Sarah found her, she tapped her on the shoulder and said "Becky, why does everyone like you?"
"I'm not in the mood, Sarah," said Becky. Or rather, Jon in Becky's body. But Sarah didn't know that.
"This thing doesn't work!" exclaimed Sarah, taking out the stone to look at it. Jon/Becky could hardly hide his excitement, but he decided not to make a scene. Instead, he carefully followed Sarah, who threw the rock into the trash. "I knew there wasn't any such thing as a magic rock," muttered Sarah.
Jon/Becky snatched the rock from the trash, and looked around for Karyn. Something was definitely wrong. He had to tell Karyn what was going on.
Then he saw Karyn with what seemed to be himself. The other "Jon" was talking with Karyn as if he knew her, and then... he took out another rock and asked Karyn something.
Of course, thought Jon/Becky. He was in Becky's body, and Becky was in his body. He kept his memories, but it seems Becky didn't. So Becky not only seemed to be him, but she thought she was him, and even knew everything he knew! What could he do?
