Later that night, Romeo hides until Mercutio and other friends stop calling for him. Then he apostrophizes Juliet as the sun, the purest, brightest star. The girl steps forth on her balcony to lament her attraction for an enemy, and Romeo comes forward. The two ecstatically pledge their love but are interrupted by some Capulets searching for a Montague page. Then Romeo and Juliet tenderly bid each other good night.
At Friar Laurence’s cell, Romeo appears at daybreak, followed by Juliet and her nurse, Gertrude. The priest agrees to marry the young lovers in the hope that their union will end the feud between their families.
Outside Capulet’s house, Romeo’s page, Stephano, sings a mocking song, which provokes a fight with Gregorio and other Capulet retainers. Mercutio protects Stephano and is challenged by Tybalt, who insults Romeo when he tries to make peace. Mercutio duels Tybalt to defend the Montague honor and is slain, whereupon Romeo kills Tybalt. The Duke of Verona stops the bloodshed, banishing Romeo from the city.
At dawn in Juliet’s bedroom, the lovers exchange words of adoration before Romeo reluctantly leaves for exile. Capulet and Friar Laurence greet Juliet with news that she is to wed Paris that very day, but the priest gives her a sleeping potion that will make her appear dead. He promises that she will wake with Romeo beside her. Juliet drinks the potion, and when Capulet and the others arrive to lead her to the church, she collapses.
In a gloomy tomb, Romeo soliloquizes on his beloved Juliet, whom he believes dead. In despair he takes poison, only to see Juliet awaken. They hail a new life, but Romeo soon falters. He bids farewell to the frantic girl, who grasps his dagger and stabs herself. The lovers die praying for God’s forgiveness.
