Remus shook his head as James came to Sirius' defence in their silent exchange. "Because he's annoyingly observant when he wants to be, like when you're trying to hide the fact you turn into a slavering monster once a month," he said with a laugh. "I've never underestimated your husband's ability to pick up on details when I least want him to, James. At fifteen, the fact I can't see half the visible colour spectrum would have been one of those details."
He opened his mouth to refuse details at the same Sirius forbade the sharing of them and ended up chuckling instead. "You heard the man, no details."
Not that he ever would have shared details in the first place. He wasn't likely to even joke beyond the subtle innuendos they'd already exchanged, which was something else he wouldn't have done a year ago. Still, he couldn't help choking a little when James kicked their teasing up a notch, leaving Remus without any sort of a retort he felt safe to utter.
Instead, he focused on sending two of the ornaments up near the top, but placing them low enough they wouldn't interfere with whatever topper they might have to place up there.
