No one believes that Bob is a wizard, they all just think he’s crazy. They keep him in a single room: a bed, a terrible flickering fluorescent light, and four white walls. They believe that any other embellishments simply disturb him and increase his delusions. Soon after anything is added to his room he soon begins chanting over it or dismantling it or staring at it intensely while muttering. To them, everything he does is just more proof he is completely out of his mind. To Bob, everything these infuriating dolts do keeps him from obtaining the ingredients he needs to perform a spell to escape, leaving him stuck in this terrible place.
Bob needs more than just the bed and the bulb to perform any of the spells capable of releasing him from his imprisonment. He is left without the means to prove to them he isn’t insane. Bob doesn’t look like wizards in the stories we most often see in America, he isn’t the sort of guy you would notice, nudge your friend and whisper, “Ha, that guy looks like a wizard.” That’s sort of the point. Wizards have been carefully adjusting public assumptions about wizards for a long time, to ensure that no one thinks they exist, and that even in the most open-minded moments would be expecting a wizard to be a tall white man with a great white beard and a pointy hat, or else a little English boy with glasses. No one suspects a very short, 30-something black man with a neatly trimmed goatee. Of course, even with all the work of disinformation wizards have done over the years there are still centuries of stories before they started their public relations campaign. Thus, there are all sorts of stories of wizards who are short black men throughout the history of the world, many of them true, but no one on staff at St. Albert’s Mental Hospital have ever heard or read or seen any of these stories.
Of course, his once pristine goatee is gone since the unfortunate event of his being institutionalized, now he just has a growing beard. The beard makes him look more stereotypically wizardly than he had before, but unfortunately for Bob wizards have done an excellent job convincing everyone that wizards are imaginary. They’ve done such a great job that now the best way to convince someone that you’re not a wizard is to tell them that you are, in fact, a wizard. It leaves Bob in a bit of a predicament.
