"They could be married, pretending to have an affair, and drunk." Remus spoke calmly, without smiling, but the laughter was in the look he shot the two of them. He couldn't imagine being as open in public as the two of them were, even now that he and Regulus weren't hiding their relationship any longer. But, it was good to see them so happy.
He did laugh, however, as Regulus presented his alternative form of occupation for his and Sirius' time. "Pads, I do believe your brother is insinuating we actually are old." He shot his lover a mock glare, before nodding his own agreement. "Between the two of us, I'm sure we could make quick work of the location scouting and have time left to booby trap the house before the two of you return."
Not that he thought Kreacher would let them get away with booby trapping that house!
Snorting softly, he smirked at James. "Now why would he only want to look as good as you when he's already the best looking one at this table?" he teased.
