Shakespeare emphasizes the use of dramatic irony for comedic effect, particularly in Twelfth Night, by employing mistaken identification. Identity confusion is the central theme of multiple tale arcs. Shakespeare frames the plot around the resolution of these two love tales through the incidents of mistaken identity in the two main story lines: Olivia confuses Sebastian for Cesario, and Orsino thinks Viola is her masculine disguise (Cesario). While the characters struggle to sort things out, he also hopes to make the audience laugh. The spectator is amused by Olivia’s inadvertent homosexual impulses (such as falling in love with Cesario, who is actually a woman) and Orsino’s unease with his developing feelings for Cesario/Viola amid all of the confusion.
