Setting aside the issue of bats dirtying the mansion, he hates blood because it messes up his mouth and dislikes pre-packaged blood, so he usually settles for unsatisfying tomato juice.

He demands they "take responsibility," but hasn't thought about what he actually wants them to do. He is perfectly serious.
