"Why do you wear it like this?" Amberdrake asks, because it seems very deliberate. Like that breastplate that isn't actually legitimate armor. (And real armor is something Drake is familiar with.)

He doesn't try to move it or anything, just lifts one end in his fingers and eyes it intently. He's seen it go off before, albeit during a lot of chaos. And of course he knows it rolls up into a scroll when Sanzo isn't wearing it. So why doesn't it just stay in scroll form?
