When Feste returns to Olivia’s court, Malvolio is insulting about his skills as a jester.
‘I marvel your ladyship takes delight in such a barren rascal…unless you laugh and minister occasion to him, he is gagged’ (Malvolio, 1:5)
When Malvolio is locked in a dark room, Feste visits him in disguise as Sir Topas and also as himself. Malvolio pleads with Feste to help him write a letter to Olivia.
‘Good fool, some ink and paper, and light, and convey what I will set down to my lady’ (Malvolio, 4:2)
Feste agrees to help Malvolio but he doesn’t rush to take the letter to Olivia.
‘I should have given’t you today morning but as a madman’s epistles are no gospels, so it skills not much when they are delivered.’ (Feste, 5:1)
When the truth of Maria’s forged letter is revealed, Feste reminds Malvolio how he spoke of him before, and how Feste is now revenged
‘But do you remember? “Madam, why laugh you at such a barren rascal. And you smile not, he’s gagged.” Thus the whirligig of time brings in his revenges’ (Feste, 5:1)
