O monstrous beast! how like a swine he lies!
The Lord's decision to punish Sly, by transforming him from a "beast" to a "nobleman," anticipates the way Petruchio will force Kate to change from a "shrew" to an "obedient wife." Both of these forced metamorphoses raise Kate and Sly to more acceptable social roles, but Shakespeare calls into question whether these changes are permanent or even genuine.

I know the boy will well usurp the grace,
Part of the Duke's elaborate plot to turn Sly from a "swine" into a nobleman involves the transformation of his servants (and himself) into role-playing characters, a reminder that all actors (including Shakespeare) undergo transformations each time they set foot on stage.

And you are well met, Signior Hortensio.
Gremio has no idea that the tutor he hired for Bianca is really Lucentio, a young man who has fallen in love Bianca. In the play, physical disguises are modes of deception that suggest all forms of transformation are temporary and not to be taken at face value.
