Karyn's power obsession

"I wish that we were at the school, in an empty room." Karyn said. Suddenly, the two were in an empty room at the school. "Karyn, why did you wish that?" Jon asked. "Well Jon, I was just thinking. You have infinite power inside you, and that can be dangerous, if it falls into the wrong hands." she said, still touching Jon's shoulder. "I wish Jon couldn't move until I say he can." Karyn said. "What...why?" Jon asked, looking worried. "Well, like I said, the power of the stone should be in the right hands. Mine! Now, how to keep access to you, and keep you from others. I wish that I would be able to transform Jon into whatever I want, inanimate or living, and that he wioll keep his mind." Jon looked horrofied. "Why?" Jon asked. Karyn then closed her eyes. "Sorry Jon, but at least you'll get to keep your mind no matter what you become. Now...what shall you become?"
