There is a small ethnic Korean population in Odessa and other majority Russian areas! The more you know, etc.
Bohdan's army is called the Shashka after this. An iconic Cossack symbol that is inherently violent...
For those of you not up on your Ukrainian demographics, most ethnic Ukrainian Ukrainians live in the west and central parts of the country. In the alternate history of the comic, Bohdan's little gang of ultranationalists come mostly from these areas. The Odessan woman and Yana are probably speaking Russian (which Yana would be fairly fluent in) but it would be plain from her accent that she is more comfortable speaking Ukrainian and is probably from a rural area to the west.
Yes, they are using cigarettes as a makeshift currency. People (including non-smokers) have done that at various times and places, and it's very cool to study -- it follows the same rules as an official currency. Ukraine suffered severe hyperinflation in the first few years of independence, topping out at over ten thousand percent in 1993 (Yushchenko was a major force in getting a sensible currency in place, go him.) In this alternate history mess, the inflation is still pretty high in (alternate) 1996, so she's not even taking the "coupons."
Thanks! Yeah, I had no idea there were descendants of Koreans in Russia and majority-Russian areas of Ukraine -- comics are educational? They're called Koryo-saram, and I had to include one of them. :)
