The lost brother and sister are standing together at last. Their resemblance explains the bewildering encounters that have filled Shakespeare’s Twelfth Night. Olivia discovers that the person she has married is not Viola in disguise but Viola’s brother. Orsino can begin to understand the young attendant who has been carrying his declarations of love to somebody else.

As surprise becomes happiness and further marriage plans take shape, another member of Olivia’s household comes back to mind. Malvolio has been confined as a madman. Feste has a letter from him.

The Fool admits that he should have delivered it that morning, but makes a joke of the delay. He begins reading in a manner Olivia will not tolerate, then defends his performance as appropriate to the letter’s supposedly mad contents. Only when Fabian takes over does Malvolio’s account proceed. Before he can enter the scene himself, his appeal has become another opportunity to perform him.

The letter is lucid. Malvolio describes being kept in darkness under the authority of Olivia’s drunken relative. He still has the letter that induced his strange behavior and wants it examined. Orsino thinks the writing sounds sane. Olivia orders his release.

This does not retroactively make Malvolio an agreeable man. Earlier he objects to Sir Toby’s late-night drinking and singing, rebukes Feste’s wit, and imagines the authority he would enjoy as Olivia’s husband. The fantasy includes making other people wait while he prepares to lecture them. Shakespeare gives his self-importance a comic shape before the punishment begins.

Maria understands that vanity. She imitates Olivia’s handwriting in a letter that seems to offer love and advancement, then leaves it where Malvolio will find it. He works hard to fit its ambiguous clues to himself. He obediently smiles, wears yellow stockings with crossed garters, and treats others with the hauteur he believes his mistress desires.

His eagerness makes the deception possible. It does not mean that everything subsequently done to him is something he chose. Accepting a supposed invitation to dress and behave oddly is not consenting to confinement or the removal of any means of protest.

When he appears before Olivia, the two are effectively in different conversations. He makes references to a love letter she has never written. She sees bewildering conduct and asks that he be cared for. Her concern supplies Toby and his companions with an opportunity to turn care into custody.

In the dark room, the trick develops a second stage. Feste puts on a gown and beard to impersonate Sir Topas, a cleric. Maria points out that the costume is unnecessary: the prisoner cannot see him. Others outside can, however. What is inaccessible to Malvolio remains a joke available to the watchers.

Malvolio says that the room is dark. The supposed cleric insists that it has bright windows and that the darkness lies in Malvolio’s ignorance. An accurate description of the conditions cannot enter the exchange as evidence. It becomes another symptom to be corrected.

He asks for a reasonable test of his understanding. Feste questions him about the belief that a human soul may pass into a bird. Malvolio can identify the idea and say that he rejects it. Sir Topas announces that he must remain confined until he changes his opinion. The test requires agreement with the examiner, not the exercise of judgment.

Feste then returns to his own voice while allowing Sir Topas to intervene as though two people were speaking. The man inside has only sound to guide him. He does not know that two apparent routes to help lead to the same performer.

Malvolio repeatedly requests light and writing materials. A steward accustomed to giving instructions must now cultivate the goodwill of the person who might carry his account to the mistress of the house. Getting a pen has become a condition of making his situation known.

The performers’ skill is undeniable. Feste can turn one voice into two; Maria can compose a letter that makes vanity do the work of persuasion. But the ability to end the performance is distributed differently. Outside, people can remove a beard, change a voice, or decide they have had enough. Inside, telling the truth does not release Malvolio from the role they have assigned him.

Toby has, in fact, begun to worry. His relationship with Olivia is deteriorating, and continuing the trick now feels unsafe. He wants the business ended. That is a useful change, even though the prospect of trouble for himself is not the same as understanding the trouble already inflicted on Malvolio. Stopping an injury may precede acknowledging it.

By the time Malvolio enters the final scene, the others have returned to imagining the family they will become. He arrives with the forged letter and an accusation. Why did Olivia promise affection and then permit his humiliation?

He has identified a real wrong but still misidentified its author. Being deceived does not make every subsequent inference correct. He, too, needs information he does not possess.

Olivia recognizes Maria’s handwriting and remembers that Maria first pronounced him mad. She acknowledges the deception and promises him a decisive place in judging what has happened. The letter is finally being treated as evidence rather than an occasion for another joke. What repair will look like remains unsettled.

Fabian confesses that he and Toby devised the trick and that Maria wrote the letter. Toby has married her in return. He hopes that no quarrel will spoil the present happiness: given the injuries on both sides, the whole affair should produce laughter rather than revenge.

His confession comes with an instruction about the proper response to it. Malvolio may now know the truth, provided he receives it as the conclusion to a funny story.

For the pranksters, revelation can supply the last joke. For Malvolio, it is the beginning of a different account. He must discover which words were false, who watched him obey them, and who controlled the voices outside his room. The others have reached their ending while he has only just emerged from circumstances he could not explain.

Feste does not pretend that he has no grievance of his own. He recalls Malvolio’s earlier contempt for his abilities and presents the turn of events as time bringing its revenge. There is old hurt within the joke. That history helps explain his investment without making a cutting remark and prolonged confinement equivalent.

Malvolio threatens revenge on the entire company and leaves. The breadth of the threat matters. His anger could now expand beyond the people and actions responsible for it. Yet the possibility of future wrongdoing cannot become a reason why he must offer forgiveness before he is entitled to be heard.

Olivia plainly acknowledges how badly he has been treated. Orsino sends people after him to make peace, then remembers another unresolved matter involving the imprisoned captain who holds Viola’s clothes. Action is proposed after Malvolio’s departure, but the play neither brings him back nor tells us that the attempt at reconciliation succeeds.

The lovers’ happiness remains real. The shipwreck has not permanently divided the siblings; mistaken identities have yielded possibilities rather than only losses. Their joy does not become fraudulent because another person cannot share its timing. The harder question is whether it can make room for someone who has unfinished business without reducing him to the role of spoilsport.

Feste, not Malvolio, is left onstage. His song follows a life from childhood into adulthood while the wind and rain persist. The play announces its own conclusion through a performer who has just participated in the cruelty. A beautiful song can close the evening without apologizing on behalf of everyone.

Malvolio no longer has to ask for a pen from behind a locked door. That change counts. Whether somebody will apologize, whether he can accept an apology, how his own offenses should be answered, and how further retaliation might be prevented remain beyond the song.

A comedy need not wait until everybody feels the same way to end. But the fact that other people have finished laughing cannot decide when the person they laughed at must consider the matter closed.
