explain how the character duke orsion challenges gender stereotypy in the film she's a man

Duke is Illyria's soccer captain and Viola's roommate. He is in love with Olivia, but is markedly clumsy and awkward when it comes to women. He does not know what to talk about with girls, and Viola happily coaches him in how to speak to the fairer sex. In the process, and because she is disguised as a guy, Viola comes to see that Duke is actually very sensitive and kind.
