Jon looked down at himself and saw that he was in his brother's body! It must have been a body swap that happened.
"Wha ... wha ... what happened to me?!" he heard his voice yell. He looked up and saw himself standing just a few feet away. The facial expression was pure horror and confusion.
"Mikey, listen to me. It's okay," Jon said. It was so weird hearing his little brother's voice when he spoke.
"Jon, tell me what's going on," he said, settling down, but still clearly freaked out.
Jon didn't bother giving him an explanation. He reached out and touched Mikey's newly-acquired hand and said "Swap."
