Act 2, Scene 1 Romeo goes into the Capulet's garden in order to find his love (Juliet). Meanwhile Benvolio and Mercutio look for him.
Dramatic irony- We know that Romeo loves Juliet and is sad that he can't see her. Benvolio and Mercutio believe that Romeo is still upset over Rosaline, who he loved before he met Juliet .
The above quote helps demonstrate dramatic irony because Benvolio and Mercutio think that Romeo is hiding because he is upset about Rosaline. Little do they know, Romeo is trying to find Juliet whom he now knows, The audience knows this, but the characters don't.
"I conjure thee by Rosaline’s bright eyes, By her high forehead and her scarlet lip, By her fine foot, straight leg, and quivering thigh, And the demesnes that there adjacent lie, That in thy likeness thou appear to us."- Mercutio
"The ape is dead, and I must conjure him"
Mercutio humorously compares Romeo to an ape.
Romeo is passionate- "Can I go forward when my heart is here? Turn back, dull earth, and find thy center out." He is talking about his heart and how he is so passionate towards Juliet that he must go find her. He is passionate enough that he would risk his life to go into the Capulet's garden to see Juliet even though he had just met her at the Capulets party.
Romeo is a lover. Mercutio says "Romeo! Madman! Passion! Lover! Show yourself in the form of a sigh." Here he id describing Romeo as a romantic which the reader finds out to be very accurate based on the outcome of the play. Romeo's love for Juliet shows all throughout.
Mercutio is witty. When Romeo is missing Mercutio takes advantage of the situation by making fun of Romeo. "The Ape is dead" I must conjure him" I conjure thee by Rosaline's bright eyes..." Here Mercutio is making jokes about Rosaline and Benvolio tells him that if Romeo hears him he will be angry.
Mercutio is a good friend. "My invocation Is fair and honest. In his mistress' name I conjure only but to raise up him." Here he is saying that what he's saying about Rosaline is fair and honest and that all he's trying to do is to get Romeo out of hiding. This shows that he cares about Romeo and his feelings.
