The boy poking his head into the room is ... odd looking, to put it mildly. Since it's no longer class hours, he isn't wearing his robes, so it might take a moment to connect the tall, lanky boy in weird clown face paint? And polka dotted pajama pants and a t-shirt with the the messy-haired third year Slytherin who always does so terribly in his class.

"Uh ... professor?"
