Bellatrix was like a witch from a Muggle child’s nightmare. She hung over Hermione leering, crying, "Crucio!" over and over with mad, desperate glee. It was like nothing Hermione had ever experienced or imagined. It was incomparable, worse than anything...ever. Hermione couldn’t think while it was happening, couldn’t breathe; all she could do was scream until her throat gave out, flayed and raw. She understood why Neville’s parents had gone insane, and wondered if she would – when she would.
