Prince Escalus appears in Acts 1 and 3 to end the duels between the families and to hand out appropriate punishments to the people who have been fighting. He is also a mechanism for the audience to know or learn specific details of the brawls that may have been missed. In both Act 1 and 3, Benvolio recounts the fights to the Prince.
