Looking at the Wikipedia list of characters I see two mentions of russian characters. Doorman and Prince. Don't see anything about them only being able to speak Russian though, but that's just from wikipedia. I suppose after Gards claims maybe day two we can quickly fill you up with 50% of the vote so you can elaborate on who you're supposed to be, and then someone who has seen the show can weigh in. Then we can unvote you, then spend the rest of the day as normal.
By the way Gossip Girl has a Japanese Girl that's a genius scholar. NOT RACIST AT ALL
