Wow, this is awkward, but if Desmond pulled himself together enough to grin wryly at Roddy, he could pretend he was talking to just another customer at the bar. Or something. No need to get too personal about it -- and if he didn't directly address it, Desmond wasn't about to either.

"... right. Uh. Nice to meet you face to face and everything." Tentatively, he holds out a hand to shake. "Did you volunteer for this?"

Because if he did, Desmond also desperately wants to know if the costume was his choice or foisted on him.
