"I am!" Sirius (who would very much describe himself as a man) agreed, equally excited because Miles was not British, and that was cute. He shook hands with him and smiled all dimples. "It'll be a riot." He was sure of it. And he was pretty sure he could handle a little bit of space with a bubblehead charm if the going got real tough. Hopefully it wouldn't come to that.
Gwen was a right knock out when she showed up and Sirius decided that he liked the both of them right at once, especially when Miles got absolutely weird over everything. "Sirius. Wotcher?" he introduced himself to Gwen with a wink and then wandered over to one of the doors, glancing at them both over his shoulder. He'd go first. That wasn't a problem.
"Ready?" He didn't really wait for an answer though, before yanking a door open and peering through.
