That wretched boy deserved it! I will try to make this as fast as possible, and leave your dying body behind!
You ended my friend`s life, now you will pay!
I`m fortune`s fool!
THIS, is what you deserve!
Romeo, stop! Help me, please! Give me mercy!
Because of you breaking the law, you would be killed, but since Tybalt had killed first, we would have been the one put to death anyways. So, you will now be exiled from Verona.
So, we have heard from many towns people that you slew Tybalt...
We have decided to pardon your death, but, you will never be able to return here again.
Romeo runs back into Tybalt. Romeo tells him that because of his friend`s death, he will kill Tybalt now. Tybalt agrees with the fight, because he thinks that he will easily win.
Romeo fights out of anger, and kills Tybalt. The other towns people that are around see Tybalt, and the state that he is in, then quickly report it to the Prince, Lady Capulet, and Lord Capulet.
Lady Capulet, Lord Capulet, and the Prince all decide to punish Romeo by exiling him, and telling him to never return to Verona again. They decide to not kill him, because Tybalt started the whole situation by killing Mercutio. He was the first to break the law.
