I think that writers crossed a line in this episode. Using fictional country and mixing polish and russian langugae is in a matter of fact insulting. Zemenia is supposed to be a country from eastern europe and according to writers it is constantly in war for 600 years. There are no wars in this part of Europe and none of the Eastern Europe countries is in any kind of armed conflict.
I get it, they hired Polish actress so she can speak fluently 'Zemenian' language, but why Monk is trying to speak Russian ? Is this just a writers' ignorance or what ?
