"Colluptorus!" Draco cried, aiming his wand first at the door she was headed for, and then the door she'd just escaped from. She'd have to make it across the room or behind him to get to another exit. He physically saw her recalibrate before he dodged around a wall that Hela had transfigured in an apparent attempt to hem them in without causing harm. Rather clever, as it made him retreat instead of physically knocking him back. Adelaide changed course, heading for the wide double doors Draco had been shepherded away from, and they swung open at her approach. She was deflecting his curses, but appeared to be guarding the ruby. Something important there, then.
