A misunderstanding happens between Friar John, Friar Lawrence, and Balthasar about Juliet's plan. Balthasar, Romeo's man comes to Mantua to deliver news from Verona, that Juliet died. Romeo is devastated and agonizes over Juliet's death. Friar John says,"Her body sleeps in Capel's monument/, And her immortal part with angels lives/ I saw her laid low in her kindred's vault."
Romeo calls for an Apothecary, a pharmacist-like person who sells drugs, poison, and medicine. He buys poison form him in exchange of gold for the poor Apothecary. Romeo's plan is to go to Verona and take the poison next to Juliet in her chamber, so he can die next to her. The apothecary says, "Put this in any liquid think you will/And drink it off/...If you had the strength of 20 men, it would dispatch you straight." Romeo says, "There is thy gold-worse poison to men's souls..."
Romeo goes to the Capulet's vault, to find Paris there. Paris accuses Romeo of being the cause of Juliet's death. Romeo and Juliet both fight and Romeo ends up killing Paris. Before Paris dies, his last wish was for Romeo to let Paris lay next to Juliet in the tomb. Paris says, "This is that banished haughty Montague/ That murd'red my love's cousin -with which grief/ It is supposed the fair creature died...O, I am slain! If thou be merciful,/ Open the tomb, lay me with Juliet."
After Romeo killed Paris, he drinks the poison that the Apothecary gave to him and lies dead next to Juliet. "O true apothecary! / Thy drugs are quick. Thus with a kiss I die. [Falls.]" Later, the friar walks in hoping that he can retrieve Juliet to his cell and save her and Romeo, but he finds Romeo dead and JUliet awake.
The friar walks into the chamber and found Romeo in dead. Juliet wakes up from her 42 hour sleep and finds her lover dead. The friar tells Juliet to come with him so he can make her a nun, but she refuses to leave. Juliet is so devastated over Romeo's death that she decides to take her life with Romeo's dagger after the friar left. Juliet says, "Then ill be brief. O happy dagger! / This is thy sheath; there rust, and let me die. [She stabs herself and falls.]"
Lord and Lady Capulet, Lord Montague, friar, and the Prince, all find their loved ones dead. They grieve their death and Montague shares that Lady Montague died because of her heart broken over Romeo's exile. The friar explains how Juliet and Romeo were married by him. He explains Juliet's plan of how to reunite with Romeo and escape her marriage to Paris. The families end their ancient feud and make amends. Capulet says, " O brother Montague, give me thy hand. / This is my daughter's jointure,for no more / Can I demand."
