Draco tried to disarm Voldemort and they were all knocked back several feet, he felt his shoulder dislocate again and Hermione’s soft grunt alerted him that she was injured too. The Dark Lord was now using wandless magic to protect his back, keeping them pinned to the ground as he focused on the string of light between wands. Harry's spell was the only one to get close to its target, their connected wands vibrated as both wizards clutched them with the knowledge that should they lose control, it would be their last breath.
