Romeo slew Tybalt, Romeo must not live.

Prince. Romeo slew him, he slew Mercutio;

Who now the price of his dear blood doth owe?

Montague. Not Romeo, prince, he was Mercutio's friend;

His fault [concludes] but what the law should end,

The life of Tybalt.

Prince. And for that offence

Immediately we do [exile] him hence.

I have an interest in your hate's proceeding,

My blood for your rude brawls doth lie a-bleeding;
