Those funky shoes that Brandon was wearing when he tripped over the sandbag remind me of the stunt shoes Michael Jackson wore for that music video when he appeared to bend impossibly far forward. His shoes racked into pegs in the floor to allow for the illusion. Does Brandon use these to stand up straight?
He's too frail. He'd fall over and break off at the knees if his feet didn't move.
I think they use them to hang him up at night so he can't wander.
