Q licks his lips. This couldn't possibly get any worse. He hopes. "Loved you," he says simply. "I didn't mean to Severus," he adds earnestly. "It just sort of...happened." No, you cannot die of embarrassment. You can only want to desperately.
"Ah," Q nods. Say what you will about his parents (and he does), at least they didn't think some people were better than others just because of who their ancestors were. That concept they had passed on to their son. "Perhaps you should have set them on fire. Accidentally of course."
