In this scene Romeo sneaks over the wall and is standing under Juliet’s window when he hears her talking about him. The second line of the scene is the famous:
But, soft! what light through yonder window breaks?
Romeo is referring to Juliet as “light.” Juliet’s then utters her equally famous line:
O Romeo, Romeo! wherefore art thou Romeo?
Romeo reveals himself and what follows is a conversation in which young “lovers” declare their love for each other. This is their second encounter. The first was brief, occurring at the Capulet’s party.
Juliet’s problem at this point is trying to fathom Romeo’s intentions. Is he just looking to take advantage of her, or does he really love her? And, of course, there is the serious problem of their family’s running feuds. So Juliet arranges to force Romeo to commit himself.
Three words, dear Romeo, and good night indeed.
If that thy bent of love be honourable,
Thy purpose marriage, send me word to-morrow,
By one that I'll procure to come to thee,
Where and what time thou wilt perform the rite;
And all my fortunes at thy foot I'll lay
And follow thee my lord throughout the world.
Juliet plans to send someone to Romeo the next day to find out when and where they will marry. She promises to follow him anywhere if he will follow through.
