They let Granger rest for a bit. Until Potter had another one of his fits on the floor. Since the first one, he hadn't dared sit anywhere else. It was as if he knew the Dark Lord would make an appearance any time and he wasn't prepared enough to keep him out. Draco understood this. The Dark Lord was a sick bastard and if he was in a mood, he didn't blame Potter for not being able to keep him out of his head.
