"Hermione, The Dark Lord was coming, and I couldn't trust you to not divulge that I gave you the wand that killed my husband. I didn't want him to know I hoped to escape. I was scared, and wanted to survive. I wanted to take my son away from all that. I'm sorry I sacrificed you in order to leave, but if the situation were reversed, wouldn't you have done the same? To save Harry or Ron's life, when you saw me as only a Death Eater's wife?"
