A comment like that should've angered her, the way people thought about her family. That they were all bad people. Granted, Bellatrix didn't fool herself into believing she was a good person. She knew she did things that other people thought was wrong without batting an eyelash; she knew she was passionate about the things she believed in, and she got carried away. She wasn't a good person by any means.
But that didn't mean the rest of her family was the same.
Still, Bella cracked a smile and let out a little chuckle. If anyone else had said something like that, she would've slapped them, unleashed a string of curses at them, but Scorpius was her nephew, and so far the only family member she could stand being around besides Regulus. "I suppose that's true."
