Moana laughed at the man's antics with the grill, and decided that approaching wouldn't be so bad, after all. When she got closer, she called out, "Are you from Pax Letale?" If he looked confused, she'd distract him for a minute by flirting and then make her excuses. It was entirely likely, since there were probably a lot of people celebrating on the beach.
Since she still hadn't met most of her neighbors, trying to recognize a gathering of them over a gathering of complete strangers was next to impossible. That was fine, though, since normally she had no problem with potentially awkward introductions... unless, of course, someone expected her to go into details about her job. Hopefully, this wouldn't be that sort of gathering.
