Twelfth Night — Act 4, Scene 1: Before OLIVIA's house.

Sebastian, walking alone, is stopped by Feste the clown, who jokes as if Sebastian were the messenger Cesario and claims Olivia has sent for him. Sebastian tells him to leave, but the clown keeps teasing until Sir Andrew, Sir Toby, and Fabian arrive. Sir Andrew attacks Sebastian, and Sebastian fights back, thinking everyone is mad. Sir Toby tries to restrain him, then Olivia appears and orders the men to stop. She mistakes Sebastian for Cesario, dismisses the others, and asks Sebastian to come with her to her house. Sebastian is stunned and confused by her sudden attention, but he agrees to go with her.
