He aimed the device at his sister, and then he pointed it to himself.
"Jon, what are you doing!?" Karyn screamed, "I don't think you want to--"

Zoe was still wearing the fishnet gloves on her feet. She now was wearing the boots on her hands as well, making holding the device quite difficult. She dropped it on the ground.
"Damn," Zoe said, "I should've never switched those boots and gloves. It's making using this device really difficult. Maybe I should just take them off."

"You just THINK you're me, because that's what the Role Exchanger did." Zoe retorted, "I KNOW I'm me because I put in a wish with the stone to always notice the changes."
