Plot

Well, since there are no English subtitles on the internet (at least not from S02 E09 onward) and my Bulgarian is a bit rusty (I can understand 20%, being Slavic and all, but that's hardly enough), and there are no official foreign releases (at least I can't find them), can somebody tell me the events of second half of season 2 - season 4

I was hooked on the series and now I need some closure :)
