Could you not take some occasion without/giving? (III.i.44)
You shall find me apt enough to that, sir, an/you will give me occasion.(III.i.42)
Alive in triumph, and Mercutio slain!/Away to heaven, respective lenity,/And fire-eyed fury be my conduct now.—/Now, Tybalt, take the “villain” back again/That late thou gavest me, for Mercutio’s soul/Is but a little way above our heads,/Staying for thine to keep him company./Either thou or I, or both, must go with him.(III.i.127)

And for that offense/Immediately we do exile him hence. (III.i.196)
At the beginning of the scene Mercutio and Benvolio are walking in the streets of Verona and Benvolio feels bad about what he thinks is going to happen because it is a very hot day and the Capulets are in the town. Tybalt and some servants arrive there searching for Romeo but he is not there. So, as a friend, Mercutio try to convince Tybalt to fight with him instead of Romeo, by insulting him.
Device: Dramatic Irony
In that time Romeo arrives there and try to stop the fight, because he is married with Juliet. Meanwhile they ignore him and start the fight. Romeo steps between them and Tybalt, while Mercutio can't see him, kill Mercutio. Romeo feel so bad about it and go back to Tybalt to fight him. In the fight Romeo kill Tybalt.
Theme: Difficulty to stay together
After kill Tybalt Romeo goes away and the citizens, the Capulets and the Prince arrive there. The Prince there ask to Benvolio what appened there, and Benvolio tells him everything. After analyzed the situation the Prince decide to not put to death Romeo but he decide to exile him from Verona.
Here the device used by Romeo is the dramatic irony. He uses it while he is trying to stop the fight between Mercutio and Tybalt. He is saying that he love Tybalt more than what he think. He is saying that because he married Juliet so they are supposed to be in the same family.
"I do protest I never injured thee/But love thee better than thou canst devise/Till thou shalt know the reason of my love.And so, good Capulet, which name I tender/As dearly as mine own, be satisfied." (III.i.69)
A theme that is developed in this theme is the difficulty, that becomes always stronger, to Romeo and Juliet to stay together. In fact the first time they met they didn't even know that Romeo is a Montague and Juliet is a Capulet. Moving forward new problems start to come like Tybalt's acting, the marriage between Paris and Juliet and Romeo that has been exiled.
