That afternoon, Juliet's first cousin Tybalt, furious that Romeo had attended his family's ball, insults him and challenges him to a brawl. Romeo regards Tybalt as family and he refuses to fight him, which leads Romeo's best friend, Mercutio, to fight Tybalt instead. Despite Romeo's efforts to stop the fight, Tybalt badly wounds Mercutio, who curses both the Montague and Capulet houses before dying. Enraged over his friend's death, Romeo retaliates by fighting Tybalt and killing him. Romeo is subsequently punished by the Prince with banishment from Verona, with the threat of death if he ever returns. Romeo, however, sees his banishment as worse than the death penalty, as Verona is the only home he has known and he does not want to be separated from Juliet. Friar Laurence eventually convinces Romeo that he is very lucky and that he should be more thankful for what he has. Romeo then secretly spends his wedding night together with Juliet and the couple consummate their marriage before Romeo flees.
