She didn't know what to say to that.  It launched a thousand questions but she doubted he'd answer any of them.  You hated Muggles, she wanted to say.  When did that stop, or do you still and just appreciate brilliance no matter where it comes from?  Is this some kind of gross exceptionalism, or have you really shed those prejudices like a snake moving on?   And do you despise me for being Muggle-born, for being a creature, for being this dependent?  All she said was, "You do keep things interesting."
