Was Karol a homosexual? (spoilers)
Aside from the stereotype that Karol was a hairdresser, it seems that his problem was that he was a gay man in love with a woman. First there is his strange inability to consummate his marriage with Delpy. We see he is not impotent because he can function at other times. Also his relationship with the other Pole man borders on being more than just friends, such as when he symbolically tries to shoot him in the heart. His being locked in the suitcase could be a metaphor for being in the closet.
So could the ending of the film mean that equality is established when Delpy is in prison just as he is imprisoned by his own homosexuality?
