"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.
After a bit of thought, Biff realized that following these guys would be fairly easy if they were just going to continue ignoring his existence as they had been. It could be as simple as climbing in the back of the van and staying there until they pulled up to wherever they intended to take Jon and his family, so he naturally started walking towards the van. But what could await him there? Would he be caught then? Hell, they might even just throw him out of the van when they discovered him there.
Now looking at the van, having wandered over, Biff realized he had an even safer option than that. Rushing inside, he grabbed a pen, and came back outside to write some notes on his arm. He looked to the License plate of the vehicle, intending to copy it for later investigation...
