Bole could date a girl with a father like Hydra's. You'd think he'd have more sense, but I think he likes to run risks, to some extent. Daphne wasn't exactly powerless. He could have found himself a fostered half-blood if he'd wanted someone with no defenders and he didn't do that -- the game, for him, was convincing someone like Daphne that she had no more power than someone's muggleborn servant.

So yeah. I think he could get himself in trouble sometime. Real trouble.
