In this passage "Cesario" speaks to Duke Orsino about his secrets referring herself as his father's daughter." (Viola), who kept her love a secret from everyone. The language that is written is interesting as he states a simile (a secret is like a worm eating a flower bud) that is referring to someone feeding on, the person who keeps or wants to keep them hidden.

At the point where Olivia has fallen in love with Cesario, Cesario states that he is not who he may seem to be. Therefore indirectly admitting her identity to get out of the crisis. Olivia on the other hand has not realized that fact as she is deeply in love. Olivia has no idea that Cesario is really Viola in disguise. The audience, however, knows that Cesariois not what he appears to be. A spy also hides his identity to help himself and other people. Hiding with a disguise is what a spy represents.

After researching the word stealth Olivia is referring to an action of theft or deception, which she is then comparing her love to that. She states that falling in love makes her a victim and that Cesario has robbed her heart or well being. Viola disguise has made Olivia quickly fall in love with him and will not take no for an answer when it comes to confessing her love. The picture is referring to the meaning of the line, showing that someone has stolen someones heart by just speaking or physical appearance in this case. Viola's disguise disguise plays an important role in Olivia's physical attraction as she also fell for Cesario after his looks. This is also shown in the last Act where she finds no difference between Sebastian and Viola.

Scene 4 in act 2 was mainly focused on Feste's disguise to trick Malvolio and have Malvolio to think that a demon has possessed him. Without watching the play it is hard to picture the Fool switching between his voice and the voice of Sir Topas during the prank played on Malvolio. Feste is known to imitate voices so disguising into another character is no problem. Him being disguised as a priest reflects in the picture as it is a picture of a priest. Feste has shown in this scene that you don't need to certainly change clothes to switch a character, you can also use the power of your voice to trick someone.
