It was Jem and Tessa, coming toward her down the hall. They appeared entirely engaged with each other. Jem was carrying something—folded gear, it looked like—and Tessa was laughing at something he had said. She was looking a little down and away from him, and he was gazing at her, the way one did when one felt one was unobserved. He had that look on his face, that look he usually got only when he was playing the violin, as if he were completely caught up and entranced.
