What's in a name? That which we call a rose. By any other word would smell as sweet.
Call me but love, and I'll be new baptized. Henceforth I never will be Romeo.
Act 2 Scene 3 Lines 61-62, 68
Then plainly know my heart's dear love is se on the fair daughter of rich Capulet ... that thou consent to marry us today.
Mercutio and Benvolio are wondering where Romeo is, and they think he is lamenting over Rosaline. They are blind to Romeo's love for Juliet.
Juliet says that his name does not define him, and Romeo says that he will be made new, not by the name of Romeo, and their names will not stop their love.
Romeo is telling Friar Lawerence that he and Juliet want to get married. Lawerence is surpriesed, still thinking he likes Rosaline. Their love is so strong that they want to be together as soon as possible.
