"You obstinate, headstrong girl! I am... ashamed of you! Is this your attitude after all of the damage you've done to the Wizarding World? Let us sit down. You need to understand, Miss Granger, that I came here with the determined resolution of carrying my purpose; nor will I be dissuaded from it. I am not used to having to submit to any other person's whims. I am not in the habit of brooking disappointment."
