Lord Capulet exercises discretion and does not lose his temper when he discovers that Romeo is attending his party. Given the longstanding feud between the Montagues and Capulets and their recent brawl, the audience expects Lord Caplet to approach Romeo and aggressively kick him out of his home. Instead, Lord Capulet takes the opposite approach and allows Romeo to stay without making a scene.

Lord Capulet learns that Romeo is in attendance when he questions his nephew, Tybalt, about why he is storming off. Lord Capulet attempts to calm his nephew and tells Tybalt to leave Romeo alone. He then compliments Romeo on his reputation of being a "virtuous" and "well-governed youth." In this scene, Lord Capulet plays the role of gracious host and instructs Tybalt to exercise patience and discretion.

Tybalt responds by saying that he will not "endure" Romeo, and Lord Capulet fiercely defends his uninvited guest. Lord Capulet puts Tybalt in his place by demanding that Romeo will be endured. He fears that Tybalt will "make a mutiny among" his guests and does not want to ruin the party.

Lord Capulet is also aware of Prince Escalus's decree and fears the consequences of being involved in another brawl with the Montagues. While Lord Capulet defends Romeo, Romeo happens to see Juliet for the first time and instantly falls in love. Later in the play, Romeo and Juliet get married in secret, and Tybalt seeks revenge for Romeo sneaking into his uncle's ball.
