Based loosely on William Shakespeare's "Twelfth Night, or What You Will". The school is called Illyria, which is the name of the country where the play takes place. Duke Orsino's character is based on Orsino, a duke. Duke's friends are named Toby and Andrew; in the play, Toby is Olivia's uncle and Andrew is one of her suitors. However, in the play, Viola is not impersonating her brother in particular, just a man, and she calls herself Cesario, which is the name of the restaurant seen where Sebastian/Viola breaks up with Monique and where Duke, Olivia, Eunice, and Sebastian/Viola briefly double date. On Viola's first day at Illyria, she walks by a school theatre playbill entitled "What You Will."
