In the first season, Latka's knowledge of the English language is extremely limited, and almost all of his lines are in his own language, to the point that he speaks his own language to the other characters when they answer him in English. From the second season onwards, his English has greatly improved and he is able to speak fluently with the other characters, but still with a heavy accent. In the second season, Latka becomes acquainted with Simka Dahblitz (played by
Carol Kane), a woman from his home country, and despite being from different ethnic groups who despise each other, Latka falls in love with Simka and they eventually get married (although in the first season, Latka marries an American prostitute strictly to avoid being deported back to his home country). Latka is also shown being visited by his mother Greta (played by
Susan Kellermann), who develops an attraction to Alex Rieger, much to Latka's annoyance. Latka's
dissociative identity disorder was conceived late in the series as a result of Kaufman expressing boredom at portraying Latka. This allowed him to broaden his comedic abilities with alternate personas such as the womanising American Vic Ferrari, the cowboy Harlow, the elegant Englishman Sir Geoffrey, and even Alex Rieger. In these episodes, Latka's different personas have no idea that they are the same person, and Vic even talks about Latka as if he knows him personally. While he is Alex, Latka experiences Alex's problems in life and at one point even finds the right solution to them, but comically reverts to Latka before he can tell the real Alex. Around the same time as his marriage to Simka, Latka's alternate personalities are completely eradicated by
Doctor Joyce Brothers and do not appear again for the remainder of the series. In a two-part episode in the fifth season of the series, Latka is forced to have sex with a female co-worker in a cab stuck in a snowstorm, to prevent her from dying of hypothermia with his body heat, and their priest father Gorki instructs Simka in a counseling session to have sex with someone she works with, in order to "repair" their marriage. However, since she is a housewife she is instructed do it with someone Latka works with, which befalls to Alex. When she cannot fulfill that, Simka and Latka comically divorce and subsequently marry again with a "clean slate". ==In other media==
