Benvolio foreshadows (literary device) to trouble between the 2 families by warning Mercutio about the hot day. Mercutio tells him to calm down since he worries too much.
Have I become a girl?
Tybalt shows up looking for Romeo. Mercutio is insulted by him and threatens to fight him. They use puns in order to insult each other, which is a literary device.
Fire-eyed fury, be my conduct! (Personification)
Romeo shows up, Tybalt insults him. Romeo says he loves him- which is an example of dramatic irony because we know he only says that because he just married Juliet.- Romeo then tries to stop Mercutio and Tybalt from fighting. Tybalt stabs Mercutio then flees.
Mercutio was killed by Tybalt. Tybalt was killed by Romeo, I swear!
You're all punished!
In an iambic pentameter monologue, Romeo wonders if his love for Juliet has softened him and made him effeminate. Benvolio then runs to Romeo to tell him Mercutio's died.
Tybalt returns to finish the job and kill Romeo as well. Romeo tells him that either both or one of them have to join Mercutio in death. Romeo kills him then has to run away.
Prince Escalus, the Montagues, the Capulets, and others show up to find both Tybalt and Mercutio dead. The families argue about who to blame after Benvolio explains what happened. The Prince decides to banish Romeo and if he returns, he'll be killed. Romeo's punishment is said in a couplet, which is used to signify the briefness of life.
