"Malfoy and Zabini are Section Seven elite ... and are part of all the cutting edge SS experiments to increase magical power through unnatural invocation. But Harry walloped them both without even batting an eyelid ... and now, so have you. And Harry just loves that. He was practically dancing when he and I were talking about it. It’s humiliating for Riddle and his buddies, making a mockery of all that they are preaching about Pureblood superiority, to have a half-blood and a Muggleborn wiping the floor with their elite wizards."
