Hermione's breath froze in her chest and her eyes slid shut. A knife. His father cut Draco's hand off with a knife. Not quick, clean magic like she had thought was most likely, but the torture of a knife slicing slowly through flesh and tendons and sawing through bone, and Hermione felt sick.

And then Hermione realised he was talking again, and stilled her panicked thoughts and made herself listen.
