Seamus tolerates him, and after a while, Bill Weasley, surprisingly, partners with him a couple of times. Bill’s wife Fleur is a gifted self-taught Healer, and Draco brews some potions for her, so maybe that helps convince Bill that he isn’t planning to kill them all as soon as he gets a chance. The rest of the Weasleys continue to ignore him, except for the youngest, the girl. He can’t remember her name; it’s something weird, Guinevere, maybe? She sometimes gives him a not completely hostile look.
