"Oh. Must've been when I came onboard, too." Constantine would happily admit he doesn't know much about cruise ships - as long as he gets to be a self-proclaimed expert in a few other domains where he's a tad more useful - but he was expecting at least a thousand staff to keep this ship running. Most of the people he's run into so far are other 'guests'. Or kidnap victims, depending on how you look at it.

"And you are...?" Mostly John's curious to know if there's some kind of pattern about the kind of people on the boat, but sure, he'll settle for a real or fake name, a vague job description, a religious proclamation or anything else that's offered.
