"Right behind you!" Spencer said breathlessly, twisting over his shoulder to throw stunning spells a little wildly, hoping for accuracy but willing to settle for a couple of them knocking each other over. He kept running, tripping a few times over invisible obstacles but never quite falling, and it was with some relief that he saw the castle drawing steadily closer.
He twisted to look over his shoulder again, as they seemed to be outrunning the elves at this stage, and stumbled to a halt, grabbing Mikey's arm a little awkwardly. "Hey," he said, "look," and stared. The house elves had turned, were stumbling away. Earlier this afternoon, the elves had followed them right to the doors, only a hasty spell keeping them out. Spencer frowned, watching them stumble away, tiny shapes against the night.
