What happens
Richard, now crowned king, tests Buckingham's loyalty by asking him to murder the young princes in the Tower. Buckingham hesitates and asks for time to consider, breaking Richard's confidence in him. Richard then hires Tyrrel, a desperate man, to carry out the murders in secret. Meanwhile, Richard learns that Dorset has fled to Richmond and begins plotting to marry Elizabeth, the young princes' sister, to strengthen his hold on power.
Why it matters
This scene marks the turning point in Richard's reign. The moment Buckingham pauses—asking for 'some breath, some little pause'—Richard's power begins to crack. Until now, Richard has bent everyone to his will through rhetoric and performance. Buckingham's hesitation signals that even his most loyal ally has a conscience, and Richard recognizes this immediately. His language shifts from command to calculation. Rather than push Buckingham further, Richard simply moves on, hiring Tyrrel instead. This is not the action of a confident king but of a man who senses his grip loosening. The easy charm that won him the throne is useless now; he must rule through threats and hired assassins.
Richard's attempt to consolidate power by marrying Elizabeth reveals the desperation beneath his crown. He has eliminated his rivals but created a vacuum of legitimacy—he rules through fear, not law. The marriage would join the York and Lancaster lines through his person, but the logic is transparent and brittle. Richard still believes in performance and manipulation, but the political stage has shifted. Where once his lies seduced audiences, now they merely provoke. His mind 'is changed' repeatedly; he contradicts himself, admits uncertainty. The man who opened the play with absolute self-knowledge now seems unmoored, reactive rather than controlling. The king is less secure than the schemer ever was.
