Jon looked down at himself and saw that he was a girl! It must have been a gender swap that happened.
"What the fuck happened to me?!" he heard a boy yell. He looked up and saw a Goth boy who looked like a male version of Zoe. The boy's clothes were more masculine, but they were definitely still gothic.
"Zoe, listen to me. It's okay," Jon said. It was so weird hearing a girl's voice when he was speaking.
"What the fuck did you do to me?" Zoe 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 Zoe's new male hand and said "Swap."
