Draco had been in the Room for hours before Harry had appeared. When Draco had arrived, the room had been in the form of a vast library - all manner of books and instruments lining the shelves. When, after combing through the books available to him, he had finally realised the truth of their situation, his first violent impulse had had the room suddenly dissolving all of its contents - anything even vaguely sharp had been the first to go. While he had raged and screamed in frustration at the time, later (much, much later) he had begrudgingly accepted that the room had saved him from himself. It would take even longer for him to be grateful of that fact.
