Laughing, Remus let himself be led out to the stairway. He leaned over to look up at the landings for the other floors and thought this was most probably unlike any Christmas this house had seen before. Somehow, he didn't imagine there'd been this much Christmas Cheer in the house years ago.
"Sirius is going to think you've gone mad, you realise this?" he chuckled, returning the kiss. "But, I love it. Thank you." Even if he hadn't known Regulus well enough now to connect their conversation from the Lighting to this decorating explosion, the other man's use of pronouns was a pretty good sign of what had inspired it. "Their loss if they're too slow. Show me what we have."
Remus felt about five years old again with all this and he doubted he'd stop smiling as long as all the decorations were up to remind him why he was so happy on a daily basis.
