ROMEO: Can I go forward when my heart is here?

Romeo
impulsively jumps over the Capulet's garden wall and finds himself in the Capulet's orchard,
which, unbeknownst to Romeo at the time, is just below Juliet's bedroom.

andare passing by in the street outside the wall, calling for Romeo and making fun of him. Romeo
ignores them, and Mercutio and Benvolio continue on their way, ending the scene.

ROMEO: He jests at scars that never felt a wound. (2.2.1)

A light suddenly appears at an upstairs window.

window.

ROMEO: But soft! What light through yonder window
breaks? (2.2.2)

Juliet appears at her bedroom
