Summary
Analysis
Ambitioso and Supervacuo meet with the prison officers and present the order for the execution of “the Duke’s son.” The two brothers feign sadness and regret for Lussurioso’s impending death and ask that he is killed in private rather than with a public audience.
As the order doesn’t specifically say Lussurioso—who has already been released by the Duke—the only person it could logically apply to from the prison officers’ point of view is Junior Brother. Of course, this is exactly the opposite of what Ambitioso and Supervacuo intended. They are too hasty in their search for power to notice the mistake.
