"I don't feel any different," Karyn said. She looked closely at Jon, to see if anything about him looked different. "Oh god, Jon. Your left eye is a different color."
Jon looked at himself in the mirror and saw that it was true. His right eye was blue, but his left eye was brown ... just like Karyn's.
Karyn looked in the mirror and her eyes were the same way. "It swapped our eyes?"
"I guess so."
Karyn grabbed the device and shot Jon with it.
"What are you doing?" Jon asked.
"Maybe we should switch them back," she said.
"Wait, it's random, remember? It doesn't work like that," Jon said. But it was too late. Karyn shot herself with the device.
