Nott shot an unlocking spell at Draco, getting him out of the bindings, which were tying him to the ground. Nott’s second unlocking spell didn’t make it to him as a Death Eater clashed with him. Draco didn’t hesitate, despite still having his hands and feet bound. He toppled a Death Eater to the ground and wrapped the chains between his ankles around his neck, choking him to death.
