As for the piece of cloth on his head: in the early going he’d been a little unclear on whether this was a medical thing—for they’d been doing a lot of things to his skull—or a form of attire. Some of the people who came to visit him—including most of the ones who claimed to be his friends and family—wore such coverings on their heads. Typically, they were a lot more elaborate than the thing he had . Large portions of his head had been shaved for medical reasons, but they’d left his hair long on top and in front. He could twist it into a sort of bun above his forehead and wrap that up in the cloth. Also, there was a metal band that he wore on his wrist.
