Bellatrix was Narcissa’s sister but Andromeda was the one who Cissa had always been close to. Bellatrix had been extreme since their younger days. She had a short temper and tantrums were almost daily occurrences. She was their mother’s favourite because she parroted anything mother said without a second thought. From hating Sirius for getting into Gryffindor to pressuring Regulus to become a Death Eater, she was the ideal icon for the insanity that the pureblood wizarding society stood for.
