They were acting like robots. He was about to try and kneecap one of them with the bat when suddenly he spotted one of them coming out of one of the bedrooms with his little brother, Wesley.
Now, Biff was hardly the nicest person in the world, but he would beat the crap out of anyone if they touched his little brother...not that his brother was a weakling or anything, despite only being eight.
"You perverts!" He said, moving toward the worker. Wesley seemed completely oblivious to what was going on. If the commotion didn't wake him, he wasn't going to be woken up. When he tried to get to him, he was pushed away, to the point the workers blocked his path.
He discovered after the effort that if he didn't make any move to stop them, they didn't react.
They started to remove Wesley's clothes, wrapping them in plastic and taking them away...along with the rest of Wesley's things...all bagged, wrapped, and barcoded as if they were some sort of moving men.
