This sort of dramatic display happened often in front of the Headmaster's office. It was why Severus tried his best to avoid visiting this area of the castle if at all possible. He was loyal to Dumbledore, of course, and often found himself running errands for the man, but handling his many, many disputes just wasn't in Severus' job description. And yet, here he was, walking right into another altercation. Was the Headmaster even capable of existing for one day without enraging someone? Severus doubted it.
"Fortescue," he acknowledged upon his approach, hoping the short greeting might deter the man from dragging him into whatever it was that just happened. Severus actually had an appointment with Dumbledore and wanted to get it over with quickly.
