Bellatrix might know—she had been disturbingly close to Voldemort. But Hermione had no desire to speak to her. Bellatrix had lost what was left of her sanity after Voldemort’s death and had stayed largely inactive and isolated all during Draco’s rise to power. She’d been violently wrathful upon being informed of Draco and Hermione’s marriage, and although she’d never made any threats of harm, she’d voiced her disgust and thrown tantrums at the match between her other insane ramblings, and Hermione hadn’t needed to insinuate to Draco that she never wanted to be in the other woman’s company. Draco hardly spoke to his aunt unless he absolutely needed to, and he made sure she was well taken care of but left her alone in her withered house, presumably waiting for the day she died. Hermione had never expressed gratitude for that, but he’d sensed it all the same.
