It was true that James and Remus didn't spend nearly as much time together as they once had. Part of that, in James's mind, was that they were no longer living together; before arriving here, he'd been accustomed to spending the majority of every day with Remus and Harry, used to the idea that even when he didn't see much of them during the day, they were the family he came home to at night. Here, well-- first he'd gotten used to being Cakemonster's roommate, which had been a surprise but an experience he'd really needed, and then he'd ended up where he was really supposed to be, living with his wife again. He still made plenty of time for Remus and Harry, but admittedly he did have quite a few other people to worry about, particularly since Sirius had shown up, and then Lestrange. With Lestrange here, it was more important to him than ever that he held onto the family that he stood the most chance of losing.
Remus was, much to James's eternal gratitude, not on that list. Remus was solid, he was a fixture in James's life; no matter how bad things got, they'd always held on to each other. Something about the special occasion of the Yule Ball was making James feel particularly appreciative of everything he had: he loved dancing with his family, and he couldn't help but smile at them dancing together, too. Watching Remus dancing with Harry, and Sirius dancing with Lily, James's heart felt warm with all the love that was in the room tonight.
Things were going to get difficult again, of that he had no doubt, but they really were going to be alright. It had been one thing hearing that his future was good, and it was quite another to believe it fully. It was a good feeling.
He was pulled out of his thoughts by Remus approaching him, and James looked up from his punch with an answering grin. He set the glass aside and held out his hand to Remus. "Absolutely, Moony," said, allowing himself to be led out onto the dance floor. "How's my favorite husband doing, then?"
