Oh, Augusta Longbottom! She’s basically Neville’s grandmother, and honestly, she’s such a quietly pivotal character in the series. She’s got that fierce, old-school wizarding family pride, and you see it in how she initially treats Neville – she’s constantly comparing him to his father, Frank, and seems disappointed he doesn’t measure up. That red handbag and the vulture on her hat are iconic, but they mask a lot of pain; her son and daughter-in-law were tortured into insanity by Bellatrix Lestrange.
What’s fascinating is her arc. She starts off as this almost antagonistic figure pressuring Neville, but by the end, she’s his biggest defender. When Neville leads the DA resistance at Hogwarts in 'Deathly Hallows,' she’s openly proud. Her line about it being ‘worth being put under siege to know [her] grandson’s got that much loyalty in him’ says everything. She represents that generation who lived through one war and has to watch the next one take their family. Her tough love wasn’t about cruelty; it was about preparing him for a brutal world, even if she got the method wrong initially.
Her final moment, dueling Death Eaters alongside Neville and declaring he’s his parents’ son, is a full-circle payoff. She went from embodying his insecurities to validating his courage, which for a side character is a pretty solid journey.
