Who gets angry when he sees romeo at the Capulet party?

Romeo gate-crashes the Capulet party with Mercution and the Montagues, and when Tybalt tells Lord Capulet that Romeo has come uninvited, he simply shrugs it off and tells Tybalt to ignore Romeo, because he wasn't causing any trouble. Therefore, Tybalt is angered by Romeo, and the fact that nobody else cares that he is there.
