Biondello

Biondello is another one of Lucentio's servants, though he's not as "trusty" or as interesting as Tranio. He's obedient to Lucentio and basically does what he's told when Lucentio orders him to pretend not to know that Tranio (disguised as Lucentio) is not his real master. Biondello's willingness to play along with Lucentio's scheme enables Tranio's sanctioned unruliness.
