Biff is pissed. But turnabout is fair play.

“You fucker,” Biff jumped up from his push-up and grabbed Ronald dragging him outside. “Give me the stone.” “No,” Ronald said, voice shaking. Biff could hear shouts and yells behind him as the door closed. He reached into Ronald’s pocket and peeled Ronald’s hand for his so-called magic wish stone. Making Ronald scream in pain. And threw him down on the hard top of the tennis court. “I wish no one would investigate or notice anything untoward is happening,” Biff ground out. Ronald was lying on the ground a good 10 feet away. He had crawled from where he had landed. A look of concentration on his face. Biff took a step towards him and stumbled. Every part of his body screamed. She could feel herself getting remade. What was it he had said? Biff eyed Ronald. The more he concentrated to faster a change happened. She needed to hurry. What was he turning her into?
