Olivia tells Maria that she has sent after Cesario, and asks to see Malvolio. He enters looking ridiculous in his yellow cross-gartered stockings. His constant smiling makes him appear mad, and he continually quotes the letter he found. Olivia, thinking he's gone crazy, tells him to go to Sir Toby to be taken care of. Thinking it's a ploy to see if he follows the letter, Malvolio is rude to Sir Toby and leaves. Sir Toby, Maria, and Fabian plan to tie him up in a dark room for a while so he'll learn his lesson. Sir Andrew enters with his letter for Cesario, and Sir Toby tells him it's wonderful. He also offers to deliver it to the boy. Sir Andrew leaves to prepare for the duel and Sir Toby, with no intention of delivering the letter, tries to think up some message to give Cesario orally for the challenge. Olivia comes in again with Cesario at her side and she asks him to wear her pin. He again presses Orsino's suit, but the lady refuses. She leaves but Toby and Fabian enter to talk to him. They tell him of Andrew's planned attack in the Orchard, but Cesario refuses to fight. The men lie about how good of a fighter Andrew is by saying that he is wonderful. Again Cesario refuses. They all leave, but Andrew and Toby enter. Toby tells Andrew that Cesario is mad and cannot wait to fight. Andrew is scared, and offers to give Cesario his horse if they can just be at peace. This delights Toby, because he will take the horse. Fabian and Viola enter, and Toby goes to speak with them. She still refuses to fight, but when Toby goes back to Sir Andrew, he says the young man cannot wait. They take out their swords and are about to begin when Antonio enters. He offers to take on the battle for Cesario because he thinks it is Sebastian. Offers come in to arrest Antonio for his previous crimes, and he pleads to Cesario but he doesn't know who the man is. Antonio then refers to him as Sebastian and Viola is happy that her twin may be alive and in the city. She leaves and the men think she is dishonest and a coward for leaving her friend. They decide to go after her.
