It wasn’t a surprise, really, that Draco figured it out. He’d always been smart. Never at the top of their class but only because he didn’t care to be—not when he was a Malfoy, back when being a Malfoy meant being anything at all. But Hermione knew him, and in retrospect, it was easy to spot that the way he lingered in the upper middle portion of their class rankings for what it was: a calculated decision. If anything, he was too smart for his own good. He fixed a bloody Vanishing Cabinet as a Sixth Year, for fuck’s sake.
