Lord Capulet first appears in the play as a gracious and merry host at his own family masque. He encourages the men and women to take to the floor and even orders Tybalt to overlook the fact that Romeo, a Montague, is in attendance. When Tybalt still desires to challenge Romeo to a fight we get the first look at Capulet's temper, which seems to be sparked whenever his will is not obeyed. He shouts at Tybalt, "Am I the master here, or you?" This foreshadows his violent reaction when he discovers that Juliet is refusing to marry Paris according to his wishes. This is embarrassing to him, since Paris is the kinsman of the Prince. But she remains obstinate, and he berates her, calling her a "disobedient wretch" and threatening to disown her is she refused to marry. By the end of the play, he, like Montague, is grief-stricken and remorseful as he discovers what has happened to his daughter. It is he who first reaches out to his counterpart in order to seek peace. The two men agree to abandon their old feud, and to build monuments to the youngsters.
