The moment the workmen left, Jon sprinted to Biff's side and pulled the wig-looking thing off of his head. Then he shook him as forcefully as he could.
At first, there was no response, but then Biff's eyes opened.
Jon felt relieved. "Biff, thank god you're okay."
"Do I know you?" he asked.
"What? What do you mean?"
"Who am I? What is this place?" he asked, looking around.
Jon grabbed that wig-like thing and looked closely at it. It wasn't a wig. It looked like some kind of mechanical device. Maybe it was this that messed up Biff's head.
"Come on, let's go," Jon said, figuring he'd just figure out how to help Biff later, after they got away from the workmen and this warehouse.
But will Biff go with Jon?
