Romeo and Juliet Act 3 Questions
After his wedding night, Romeo departs to Mantua in Act 3, Scene 3, following his banishment from Verona for the death of Tybalt.
If Friar Lawrence cannot help her, Juliet plans to kill herself; she'd rather die than marry Paris, which her family is arranging without being aware of her secret marriage to Romeo.
Initially, Romeo doesn't want to fight Tybalt because Tybalt is now his family by marriage, although Tybalt is unaware of this fact. Romeo is trying to avoid further conflict following his secret marriage to Juliet, Tybalt's cousin.
