4:2 Juliet returns home, where Capulet and Lady Capulet prepare for the wedding. She surprises her parents by repenting her disobedience and cheerfully agreeing to marry Paris. Capulet is so pleased that he insists on moving the marriage up a day, to Wednesday—the next day.
I’ll have this knot knit up tomorrow morning.
4:3 Juliet isolates herself in her room, preparing to take the potion. She comes up with many bad things that could happen, including suffocating in the tomb and seeing Tybalt's ghost. But, she swallows her fear and courageously takes the potion.
I drink to you.
4:5 The Capulets are busy with preparations for the wedding. The nurse finds Juliet dead and begins to wail, soon joined by both Lady Capulet and Capulet. Paris comes and joins the lamentations. The friar tries to cheer them up by telling them that Juliet had gone to a better place. Then, the musicians hired for the wedding, now out of work, begin to pack up. Peter, a servant, asks them to play a song, but they refuse. Peter and the musicians trade insults for a comedic relief ending of the scene.
Curse the day! She’s dead, she’s dead, she’s dead!
