Romeo sits outside Juliet's balcony listening to her words, then offers to fulfill her desires and change his name so they can be together. The scene ends after Romeo tells her that if she dislikes the name, he is no longer Romeo the Montague.
Romeo, give up your Montague name. Or, confess your love and I will give up my Capulet name.
When should I respond to her wishes?
Only your name is my enemy. Nothing else! Please, oh please, change it.
Then, I grant your wish! Become my love, and I will change my name!
Who are you, eavesdropping on my thoughts?
I hate my name, and telling you would not favor either of us. It is your enemy!
That voice... you are Romeo the Montague?
If you dislike them, then I am neither of those things, your beauty.
