Mercutio and Tybalt end up dueling till either one of them are dead. They both dueled and caused not only Mercutio to die but cause Tybalt to die as the aftermath. This was a turning point and the climax of the play which causes other situations to be played out as consequences.
Come, sir, your passado.
I am for you.
Romeo just was informed that he was banished from Verona and so many thoughts came through his head. He couldn't imagine a world without his lover, a world without Juliet by his side and so he attempts to stab himself to stop the suffering and punishment. The nurse and Friar Lawrence doesn't approve of his attitude and stops this from happening. In the play, it states " [ He offers to stab himself, and the NURSE snatches the dagger away .]" Friar Lawrence explains how this is unacceptable and explains how Juliet would feel if he died
Juliet is suffering from conflicting with herself. She is struggling to make a decision for herself on whether she should take the liquor and she even had a whole monologue to explain her thoughts towards the reader. For example, in the play, it states "What if this mixture do not work at all? Shall i get married then to-morrow morning? No, no; this shall forbid it: lie thou there."
What shall I decide on? Who should I trust? Should I take the liquor given by Friar Lawrence or is it all just a trick to get me killed! What should I do!?
After the duel ended, Mercutio has so called released a "curse" on both families (Capulets and Montagues) and so is the consequences of his death. This would soon be the cause of Romeo's banishment as he killed Tybalt as revenge and a lot more challenges headed for these lovers.
This day's black fate on more days doth depend; this but begins the woe others must end.
A plague o' both your houses! I am sped.
Romeo foolishly allows his stubbornness to take over and take the decision on killing himself so that he doesn't have to suffer the banishment but he lacks the thoughts for others. He never though of how Juliet would have felt if he died or how others would feel. Friar Lawrence agrees to bring up his hopes with a plan to get him back with Juliet safely.
Hold thy desperate hand! Art thou a man? Thy form cries out thou art; Thy tears are womanish; thy wild acts denote the unreasonable fury of a beast.
And so Juliet drank the potion to break the chains that will allow her to be with her Romeo and prevent the marriage with Paris the next morning. If everything succeeds, she will be able to be reunited with Romeo
