Tybalt is gone, and Romeo banished. Romeo that killed him-he is banished. (3.2.70-71)
A damnèd saint, an honorable villain! O nature, what hadst thou to do in hell When thou didst bower the spirit of a fiend In moral paradise of such sweet flesh? Was ever book containing such vile matter So fairly bound? Oh, that deceit should dwell In such a gorgeous palace! (3.2.80-86)
Alas, that love, so gentle in his view, should be so tyrannous and rough in proof!
Out of her favor where I am in love.
Hang thee, young baggage! Disobedient wretch! I tell thee what: get thee to church o' Thursday, Or never after look me in the face. Speak not. Reply not. Do not answer me.
Good Father, I beseech you on my knees, Hear me with patience but to speak a word
Here, the nurse informs Juliet her husband, Romeo, killed her cousin Tybalt. When Juliet finds out, her thoughts about Romeo are conflicting. Juliet realizes she knows nothing about Romeo except that he's handsome. In spite of this, Juliet still loves Romeo. This is an internal conflict because Juliet is now thinking about the situation more, and realizes that if Romeo hadn't killed Tybalt, Tybalt would've killed Romeo, and she would rather have her husband alive. However, she is still shocked at the fact that her husband killed her cousin.
This represents an internal conflict. Romeo loves Rosaline, but Rosaline doesn’t love him back. The sadness this causes him “lengthens his hours,” and he is now lovesick.
This is an external conflict between Lord Capulet and Juliet. They argue about what Juliet's fate is to be. Capulet is forcing Juliet to marry Paris, but she doesn't want to because she is already married to Romeo, but her parents don't know that.
