"My aunt has always been unstable," Draco said nonchalantly. "She loved Voldemort. Her second stay at Azkaban and then his death made it worse. She needed to be guided or she would pose a threat not only to herself, but others. She didn’t care much for our union. Why do you think you’ve never seen her all this time? She may be family, but I’d strike her down if she dared touch a hair on your head. Even under my control, I won’t risk it."
