Luna tells Blaise they need to split up since the snake cannot chase them both. "I'm so tired, my love." Blaise kisses her quickly and tells her to go up to the fifth floor as he stays on the fourth, Nagini slithering closer and closer. She sees he's alone and heads towards the direction Luna just went. "Oh no you don't!" He knows it's crazy, but he grabs the snakes tail and pulls with all of his might. As Nagini turns to strike, he hears a battle cry and a flash of red; Ronald Weasley slices Nagini's head clean off, saving Blaise's life.
