Valentine and Viola (now dressed as a young man, "Cesario") talk. Valentine is amazed at how much the Duke likes "Cesario," though he has only known him three days. Orsino has no idea that Cesario is actually a woman. Orsino arrives and speaks to Cesario privately, telling him that since he already knows him better than anyone, Cesario should go to Olivia and try to get her to see the Duke.
Cesario protests, saying that Olivia will never let him visit her, but the Duke tells him to be as rude as he has to be in order to get to see her. Plus, he says, Cesario's youth will make him more appealing to Olivia. In fact, Orsino muses, Cesario is so young that he almost looks more like a woman than a man. He tells Cesario to help him win Olivia, and promises him whatever he wants. Hearing this, Cesario says to himself, "Whoe'er I woo, myself would be his wife." Act 1, Scene 4, line 42 Cesario, or rather Viola, has fallen in love with the Duke.
