Bellatrix dodged the shot and rolled, stretching out to release iron chains at his legs. He screamed when they hit, blasted the iron to bits with a red spell. Hermione used his momentary lapse in attention to round on him from the opposite side of the room; a factory floor now turned into a killing field, Hermione’s spells shot off with precision. Mundungus dodged as best he could, and while he made a good sport of it, he eventually misstepped. Clipped in the leg, and Bellatrix dragging him with yet more chains. He fell, and then the blood flowed.
