Against his better judgment, Jon grabbed the bat that Biff had dropped and swung it towards the workmen stripping off Biff's clothing. It seemed to do the trick, for the moment. At the very least, it got the robot-like men away from Biff. It instead caused them to go after him.
Biff was surprised that they suddenly were ignoring him..They surrounded Jon. One of them pulled out a needle and stuck it in Jon's arm...and he quickly went limp. They proceeded to strip his clothes off and bag them. He watched as they put a hospital like bracelet around his wrist. It had a barcode, a number, and a name...Biff Meadows. Somehow, Jon fighting them off had gotten him mistaken for Biff himself...
"Oh, shit..." Biff said. But he wasn't going to throw himself at these guys again. He wasn't stupid. He needed another play if he was going to rescue his family.
