Look how Viola / Cesario talks to the Duke as a man and talks to him about Olivia, even if it hurts her inside because she loves this Duke and its painful for her to be listening to him talking about this love for Olivia. “2.4.90 sooth, but you must. Say that some lady, as perhaps there is, hath for your love a great a pang of heart As you have for Olivia. You cannot love her; You tell her so; must she not then be answer’d” It’s funny how you hear her in the beginning to talk so innocent and like a woman and then hear her talk like another soldier “3.1.95 My duty, madam, and most humble service.” You see how she changes in the play just by hearing the words she uses and how she starts talking afterwards the change of sex she had. Viola continues being passive and innocent, secretly hoping that Orsino will love her.
