Even though Draco had tried to establish his study as a common place for the two of them to work, it would be a lie to say that he didn’t appreciate Potter knocking before entering. He wasn’t working on anything volatile or something like that, but he easily could have been and in that way, it was nice that he would have to chance to put it way before having someone else enter.<br/>“It’s open,” he stated, figuring that that was enough of an answer for Potter by now. He was mostly just musing over his notes for now, excited at the prospect of receiving new stuff to add to them, but also trying to make sense of what little he did have.<br/>After all, this was probably going to be a very long process for him, and Draco found that it was helpful to revisit his notes every now and again. It was the only point of reference he had and while there were other mildly helpful works of writing out there, he was mostly left on his own.
