Draco's right arm was missing a hand. A second look revealed that the second shout she heard was Oliver repeating the action on his left. Without hands to hold his wand, he was unable to keep hurling curses in their direction hoping that one of them would eventually hit. It had been brave of Oliver to face down a wizard more than three times his age with a great deal more experience. She was proud of him and encouraged by the fact that he didn't even try to kill Draco. All he desired was to stop him. Already Oliver was a much better human being than his parents. They had a lot to learn from him. For the first time in a very long time, Hermione actually began to believe that they might even have the chance.
