"Glad that I could explain things for the poor slow Gryffindors," he joked, chuckling a little, because with anyone else, he might mean it but not with Remus, who had proven to be his intellectual equal more than once.
Regulus took Remus' hand and squeezed gently. "I'm somewhat comfortable now." He stepped closer and leaned against Remus before kissing him. "This isn't my world, but it's the world we have, so I'll find a way to learn about the Muggle world and then we'll go do things by ourselves and possibly not wearing trousers that seem a few sizes too small."
He grinned. "We're going to a restaurant, which means we'll be sitting down. My arse is fine for the duration of our meal. I'll take my chances afterwards, something about peeling off comes to mind." He put his arm around Remus' neck. "I hope you won't be disappointed if some of that confidence will be missing while I learn. You'll have to be the confident one this time around."
