I just adore your sassy Millicent, and once Viktor gets the hang of things, he's a fine match for her. ("I improvised those parts" -- haha).
In addition a great arse and tits, she's got a real flair for verbal bludgers. I love the fact that, except for a couple of minutes with Kingsley, she's never at a loss (and I'm willing to cut her slack for the Kingsley bit, given the whole mooning mix-up. That would put any girl off her form.)
Things that had me laughing aloud -- Mr Buzzy and the never-looked-at Krum poster, Milly's feeling pity for the tiny, flat-chested girl with good taste, "Weasleys come in herds," "Krummy bastard," and more.
