I think Emma Watson’s such a genius. The look on her face when she sees the scar Bellatrix left isn’t just a look of sadness and fear, it’s a look of realization. She’d never had to confront the seriousness of the discrimination towards mudbloods before— she’s always been relatively safe at school (except for Voldemort and his nonsense, of course) and has always been talented and a leader everywhere she’s gone. The only people who’ve called her a mudblood are people she acknowledges as petty and jealous.
But at that moment, she realized that it’s not just a name kids at school call other kids out of envy— fully grown witches and wizards have killed mudbloods.
