As the class forms a line, a silvery transparent figure steps silently through the wall and then leans back against it, as well as he can. Regulus gets a few curious looks from students who have defeated the boggart and are filing to the back of the classroom, but most of the focus is still on the exercise, and he watches with a faint smile as Remus guides each student without telling them what to do. He's actually good at this, isn't he?

He can't help but wonder what the boggart would turn into for him now, but they don't pay any attention to ghosts. He still waits until Remus has it locked safely in the wardrobe again and the students have almost all disappeared before he starts forward, still walking as if he's still a person and not just what's left behind. "I imagined you'd make a good professor, you know. It never came up."
