Outside on the Verona street, Benvolio and Mercutio wait around for Romeo to meet them. Tybalt and Petruccio see them first, and start a quarrel. Tybalt makes it clear that he is looking for Romeo, whom he wants to punish for sneaking into the Capulets' masked party the previous day.
When Romeo arrives, overjoyed with his recent marriage, he is deferential to Tybalt, insisting he harbors no hatred for the Capulet house. Tybalt is unsure how to deal with Romeo. However, Mercutio challenges Tybalt to a duel, so he draws his sword and attacks Mercutio. Romeo attempts to intervene, holding Mercutio back. While Romeo is restraining him, Tybalt stabs Mercutio and then exits quickly.
