Orsino, at Olivia’s estate, sends the Fool to bring Olivia to him. Antonio is brought in by officers and he tells the incredulous Orsino about Cesario’s treacherous behavior. At Olivia’s entrance, Orsino expresses his anger that Cesario has become Olivia’s darling. Cesario’s expressions of love for Orsino lead Olivia to send for the “holy father,” who confirms Olivia’s claim that she is formally betrothed to Cesario. Sir Andrew and Sir Toby enter with bloody heads, which they blame on Cesario. Sebastian’s entry at this moment untangles a series of knots: Sebastian addresses Olivia with love, greets Antonio warmly, and recognizes Cesario as the image of himself. When Cesario admits to being Sebastian’s sister Viola, Orsino asks Viola to become his wife. On the day that Sebastian marries Olivia, Viola will marry Orsino.
