Jon looked down at himself and saw that he was wearing Goth clothes! It must have been a personality swap that happened.
"What the hell happened to me?!" he heard his sister yell. He looked up and saw her standing just a few feet from him. She looked quite normal, like half the girls at school. T-shirt, jeans, sneakers. And all of her Goth make-up and piercings were gone. Jon thought he'd be pleased to see his sister this way, but suddenly he preferred Goths. It must have been because he was a Goth boy now, thanks to the swap.
"Quit yelling, you fucking idiot," Jon said. It was so weird hearing himself talk like Zoe, but it also felt right.
"What did you do to me?" Zoe asked, settling down, but still freaked out.
Jon didn't bother giving her an explanation. He reached out and grabbed her hand and said "Swap."
