Then there was Patrick O'Brien and David Pincott ... who were literally on fire. They were like two men made out of pure, red-hot flame ... burning and searing any enemies who were stupid enough to stray across their paths. Beyond them, Hermione could see Angharad and Myfanwy, back-to-back, at the eye of their own personal storm. They were sending out spiralling waves of a magical force so powerful that they were cutting through the brickwork of a prison block nearby like a circular saw. Hermione watched the display in abject awe, then she saw Neville trying to push his way through an opening the girls had created.
