Severus swooped in through the door and sat beside me before the door could swing closed. His movement seemed off; he didn't have his regular teaching robes billowing around him. Even his frock coat was gone, leaving him in his usual white Victorian-style shirt with a black cravat tucked in between the second and third buttons. It was expertly neat, even down to his pressed trousers, a leather belt around his narrow waist, clasped with a silver pair of serpents in a type of eternal struggle. It had been charmed to have absolutely no shine, to give zero reflection and to avoid attention.
