Tybalt, who was killed by Romeo, also killed your cousin, Mercutio.
Benvolio, who started the fight?
Romeo approached Tybalt calmly. Tybalt and Mercutio began to fight, so Romeo stood between them. Tybalt stabbed Mercutio under his arm. Romeo killed Tybalt out of revenge.
My nephew has been killed. A Montague must pay.
Not Romeo. He was following the law because Tybalt killed Mercutio.
Romeo killed Tybalt, but Tybalt killed Romeo. Who should be punished?
He is Romeo's friend. He's lying.
Because of this, Romeo will be banished immediately. All of you will be fined heavily because of my loss. If we find Romeo, he will be killed immediately. Excusing murder is the same as encouraging it.
