Sirius was a wreck. He wanted to be in there. He understood why he wasn't, but it felt like he had been waiting outside the door for hours. He couldn't sit still and read the way Dorcas could, not under these circumstances. Well, he probably could if he had been in the room, but being outside, and not knowing what was going on inside was maddening. For a while he paced, then he got a kitchen chair and sat facing the door, but he was far too anxious to sit still for long, so he returned to pacing, making a game of getting closer and closer to the door, before starting over. With only the width of the corridor to work in, the game didn't last long and was repeated often, he stopped only to occasionally press his ear against the door as he passed by, but the doors were thick and solid, making it difficult to hear anything through them.
The sound of the doorknob being handled came just a second before the door was pulled wide. Fortunately, Sirius was close enough, and on guard enough, to be at the threshold, wand drawn, by the time Draco got it open. "Good morning!" he exclaimed brightly, leaning against the door frame, twirling his wand in one hand like a drumstick.
