Swamped

He reaches into his pocket.

"Are you Kandrian?" he asks.

And now you're worried about just what he's reaching for.

Long is a surname of Kandrian origin, but enough people have moved out of the kingdom over the years that it's hardly uncommon to find it elsewhere. But if he has particular information of a Kandrian agent named Long, well, you've certainly had a suspicious arrival.

And if that's why he's asking - is he asking because he's working for Kandria, or because he isn't?

Either way, you suspect that giving the wrong answer could be a serious problem for you. Serious enough that you're considering using the time ether to get a more concrete clue. But before you resort to that, perhaps you have another option for dealing with this situation.
