Thirteenth Night; Malvolio's Revenge

Act 1 Scene 2

Enter Malvolio and Captain
Captain: Why dost thou come to me again?
Malvolio: The Lady Olivia wishes to speak with you. I have been sent at her suit.
Captain: Why would she see me?
Malvolio: That business is hers. She simply wishes you be brought to her.
Captain: (aside) I gave my word to Miss Viola. I can not divulge her secret.
Malvolio: Do be swift, Sir. It does not please her to be detained.
Captain: Of course. Lead me on.
Malvolio draws knife
Malvolio: Sir, 'tis my duty to tell what I can. My Lady seeks you with no great favor. She is displeased. If in your place, I would fear great danger.
Captain: I don't understand. What could I have done against the Lady?
Malvolio: 'Tis distemper between her and the Duke, as I know. Neither one is pleased.
Captain: If this be an issue of young Cesario, I hold my peace. The boy was honorable last I saw him.
Malvolio: You are sought, whatever the case.
Captain: Hast thou nothing more you can tell me?
Malvolio: The Lady did advise me to deliver this epistle should you be in question.
Captain: (reads) "M.O.A.I." What meaning is in this?
Malvolio: The end, Sir.
Malvolio stabs Captain
Exeunt
