Draco let out a shuddering breath, "It was a matter of time I suppose," he said quietly, "Mother and Father probably didn’t tell him I was claiming the vault - out of embarrassment I imagine, but once Bellatrix was free, they must have told her, and she realised the cup was inside it, and she told him. This doesn’t mean he knows that we know what it is though," Draco said firmly, stretching his hand across the table and holding it palm up; Harry reluctantly slid their hands together, "He knows the cup is gone - but he doesn’t know why. He never told anyone what it was after all, did he?"
