Go to. —Romeo and Juliet, William Shakespeare Which line from the text shows that Capulet believes Tybalt should respect him because he is Tybalt's uncle? "An ill-beseeming semblance for a feast" "It fits, when such a villain is a guest" "I'll not endure him" "Am I the master here, or you? Go to"
Capulet asks this rhetorical question to Tybalt in order to put him in his place. Capulet is Tybalt's elder and Tybalt is speaking as though he will ignore his uncle's wishes. Capulet reminds Tybalt that he is the one in charge, not Tybalt. Capulet reminds Tybalt of his position at the beginning of this excerpt as well when he says "It is my will; the which if thou respect". Here he is telling Tybalt that he wants Tybalt to leave Romeo and his friends alone. If Tybalt respects Capulet, he'll not engage in a fight with the Montagues at the party.
