It turns out that the Citizens of the Watch<span> have spread word of the street fight, and </span>Prince Escalus<span> arrives before anyone is killed. </span>The Prince<span> chides the Montagues and the Capulets for their mutual aggression, which he believes is making the streets of Verona unsafe. The Prince then orders everyone to return home and cease hostilities at the risk of great punishment. He personally accompanies the Capulets home.
