In the moment right before Sebastian's entrance in act V, scene I, Viola is surrounded by people who incorrectly think they know who she is. Why might this moment of mistaken identity be considered the most complicated moment of Twelfth Night?

Act V, scene I, is a moment of utter chaos. Some of the characters surrounding Viola think she is Sebastian, while others think she is Cesario. This case of mistaken identity sets in motion a series of complex situations. Viola is bewildered by other people’s reactions to her. Antonio mistakes Viola/Cesario for Sebastian and accuses her of stealing his money. Olivia thinks Viola/Cesario is tricking her by feigning ignorance about their marriage. She calls in the priest to testify, and Viola/Cesario earns the wrath of Orsino for allegedly breaking his trust. Sir Andrew wrongly thinks Viola/Cesario was in the duel that injured him, and he accuses her of attacking him. These complications all stem from Viola’s disguise. However, just as matters seem to be getting out of hand, Sebastian enters, and the problems are resolved.
