Jon looked down at himself and saw that he was a girl! It must have been a gender swap that happened.
"What in the hell?!" he heard a boy yell. He looked up and saw a boy who looked like a male version of Karyn. The boy's clothes were more masculine, but they were definitely still Karyn's style.
"Karyn, listen to me. It's okay," Jon said. It was so weird hearing a girl's voice when he was speaking.
"What the hell is going one, we switched genders" Karyn asked, settling down, but still freaked out.
Jon didn't bother giving her (or was it him now?) an explanation. He (or rather she) reached out and touched Karyn's new male hand and said "Swap."
