I thought for sure that Draco had died, until you brought up seeing him at the ball. I'm not sure if his being alive is sadder, or happier. I know personally I'd rather have the person I love with someone else than dead, but knowing that they love you as much as you live them and being unable to be with each other is heart wrenching. I am completely against cheating, but I wonder why they haven't snatched a moment together, hiding it from their spouses? Harry almost seems like he'd understand, as long as it didn't break up their marriage... Ah love, why must you be so difficult?
