Mosca enters with Bonario in tow and places him in hiding as a knock is heard at the door. Both young men await the entrance of Corbaccio, Bonario in close hiding and Mosca as the welcoming servant.
Timing is the important comic element in this developing plot complexion. As he enters, Bonario must barely miss the retreating Volpone. The plot must always be suspensefully on the verge of collapsing. Furthermore, theatrical surprise depends on not giving the audience a chance to catch up with the swift action. At any rate, the situation is clear. Three characters are awaiting Corbaccio; one behind a bed curtain, another in a closet, and the servant center stage.
