Percy was finally feeling better, which meant he had time to catch up with everything that had piled up while he was sick. It also meant less time with Cass. Percy had never worried about going home because of someone else. This was a new and strange situation.
Of course the random visits helped. When Cass came in, he looked up, smiling. "Hey, yourself. Are you here for a particular reason or just to annoy me?" The former meant more work, the latter meant a few minute break. It could go either way and Percy wouldn't care about either.
