Nox looked over to Lyra as she looked up at the moon, and then the large wolf saw how much Lyra worried about being a good alpha, and how much she cared about their small pack.
Part of him wanted to go over and comfort her, telling her that she was a wonderful alpha, as she was, but he stopped himself. Perhaps now she just needed to sit and think. He decided that she was probably safe for now, so he retreated back into the cave and lay down, but he didn't fall asleep, waiting for Lyra to return.
