In contrast to the romantic plot of the preceding scene, we return now to the comic subplot focusing on the duping of Malvolio. This gulling of Malvolio is one of the most comic scenes in the entire play. Sir Toby and Sir Andrew are joined by a new character, Fabian, who has been the victim of Malvolio's sanctimoniousness when he protested to the Lady Olivia that Fabian was involved in the cruel game of "bear baiting," a form of sport in which dogs barked and snapped at a bear chained to a post. As a moral puritan, Malvolio had reported Fabian for "bear baiting" because Olivia disapproved of this cruel sport. Now, however, they hope that this "niggardly rascally sheep-biter" will soon come along, and they will make Malvolio into the "bear" and will "bait" (tease) him.
They intend to fool him "black and blue." Yet, there is no genuine malevolence in their actions. They resent Malvolio's lack of human sympathy and his puritanical arrogance towards them, and furthermore they will use his own arrogant and egotistical nature to play the trick upon him. If he weren't so self-centered and egotistical, it would be impossible to play this trick upon him. Because of this, we find it difficult to sympathize with Malvolio. At this point, Malvolio is like a man who looks down the wrong end of a telescope and sees everything in the world as being diminished in stature.
When Malvolio opens the letter, he thinks that he recognizes Olivia's handwriting; we know, of course, that it is Maria's handwriting. As Malvolio recognizes certain letters, he mouths them aloud; this is a superb comic example of "echo comedy." All through the scene, as Malvolio tries to decipher the letter, the characters in the box-elder hedge continue to make humorous and derogatory remarks. When Malvolio reads in the letter, "If this fall into thy hand, revolve," he turns around on the stage, evoking roars of laughter from those in the box-hedge.
