Not my daughter, you bitch!

Didn’t you hear what they said about my sister? But you don’t give a rat’s fart, do you, it’s only the Forbidden Forest, Harry I’ve-Faced-Worse Potter doesn’t care what happens to her in here — well, I do, all right, giant spiders and mental stuff —

“Oppugno!” came a shriek from the doorway.

“Gerremoffme!” he yelled, but with one last look of vindictive fury, Hermione wrenched open the door and disappeared through it. Harry thought he heard a sob before it slammed.

Molly's curse soared beneath Bellatrix's outstretched arm and hit her squarely in the chest, directly over her heart.
Bellatrix's gloating smile froze, her eyes seemed to bulge: for the tiniest space of time she knew what had happened, and then she toppled, and the watching crowd roared, and Voldemort screamed.
