[Lucentio and Hortensio have been posing as teachers to get access to Bianca, and in Act 3, Scene 1, they both revealed their true identities to her.  While Lucentio and his servant Tranio know that the supposed music teacher Litio is actually Hortensio, Hortensio has no idea that the language tutor Cambio is actually Lucentio, nor that the man he thinks is Lucentio is actually Tranio. In front of Signor Baptista’s house, enter Tranio-as-Lucentio and Hortensio-as-Litio.]
