"Draco, I am old, I am not blind. And, I am your mother. Mother’s know everything. You’ve been smitten with that girl since you were a young child. You used to talk about her constantly. I know what happened the night that she was tortured here– the night that Bella carved that  slur  into her arm. You do realize I know all about Sanctissimus, Draco. I knew the moment the Chief Warlock informed me about your probation what it all meant. She did it for you, did she not? Not because it was moral or ethical, but because of  you. She loves you."
