How humiliating to be kept only locked and naked, but put in mitts as well as if to say he doesn’t have any decorum at all in keeping his hands off himself. Maybe this is why he’s allowed to keep his hair, a small gesture to humor him, to give the illusion that he’s still a grown man in control of his own body. However, if you look at his other pictures of him in a collar and diapers you can tell he is happiest when he is helpless and has to rely on someone else’s care and whims. That lock is metal after all….doubt it’s coming off for a long while. The hair will go eventually, along with the rest of his old identity.
