The final words of the star-crossed lovers occur in act 5, scene 3 of Romeo and Juliet.
Friar Laurence has supplied Juliet with a potion designed to induce a coma "for two and forty hours" to allow her to avoid an arranged marriage with Paris. On the night before the wedding, she takes the potion, and when her apparently lifeless body is found, her grieving family removes it to the Capulet crypt.
Although the clergyman had sent a messenger to inform Romeo of Juliet's plan to join him after awakening from her feigned death, the message fails to reach him, and Romeo is mistakenly informed that she is truly dead by his servant, Balthasar. Mad with grief, he vows to die at her side.
Romeo returns to Verona and to the Capulet crypt, where he meets the equally grief-stricken Paris. The latter, recognizing Romeo as the killer of Tybalt, provokes a duel, but is quickly slain by his rival in love. Romeo opens the crypt and is shattered as he finds what he believes to be the corpse of his beloved. His final words, as he consumes a lethal drug, are as follows:
Come, bitter conduct, come, unsavoury guide!
Thou desperate pilot, now at once run on
The dashing rocks thy sea-sick weary bark!
Here's to my love!
O true apothecary!
Thy drugs are quick. Thus with a kiss I die.
Juliet awakens to find the corpse of Romeo beside her, grasps the fact of his death, and kisses him for the last time.
Yea noise, then I'll be brief, O happy dagger!
[She snatches Romeo's dagger.]
This is they sheath;
[She stabs herself.]
there rust and let me die.
[She falls on Romeo's body and dies.]
