"We have other problems," Jon said. "Look."
They turned and saw the guy with Karyn's body feeling it in shock. Then he said "Oh crap," and ran away scared.
"Give me the swapper. I think I can still get my body back," Karyn told Jon.
"I don't have it. He does, remember?" Jon said, pointing to the girl with a guy's head, getting further away from them with every second.
Karyn looked at the guy who had her body and said "We have to stop him. He might accidentally use it. What if I never get my body back?" she panicked.
"Don't worry, Karyn. We'll get you back to normal. Come on," he said. And they ran after the guy.
