When a daughter defies her father everyone in the room feels the tension.  This tension is especially heightened when the daughter’s love interest is involved in this disagreement.  This scenario is demonstrated perfectly in Act 1 scene 3 of Othello.  

      The scene begins when the Duke and the Council are disturbed by the rumors that the Turkish fleet is planning an attack on the island of Cyprus. They are discussing a plan to send Othello there to defend it when Desdemona’s father accuses his son-in-law of witchcraft. Othello suggests that his wife should be called to address the Council. While he and the Senators are waiting for her to arrive, Othello describes how he wooed her. He would come, invited by her father, to her house and tell about his adventures, of traveling through strange deserts and high mountains, and all the terrors he had endured. Desdemona loved him for his courage and sympathized with his pains; he loved that she could show pity.

      Desdemona enters and speaks, stating her loyalty now belongs to her husband. She even plans to follow him to Cyprus. Brabantio must accept defeat. His sad acceptance of his loss is a contrast to the Duke’s clumsy effort to offer general comfort as a balm for Brabantio’s pain. Brabantio warns, "She has deceived her father and may thee". It is important to notice that Othello stands up well before public scrutiny. Love is merely "a lust of the blood and a permission of the will.” He even suspicions that Othello has slept with his wife Emilia. He continues to lay his plan for destroying his archenemy. In the final soliloquy of this Act, he makes his thoughts perfectly plain. He associates with Roderigo for his own selfish motives, not because he feels any affinity with him.

      The ending of the scene results in an argument between Iago and Roderigo, and an attempt of suicide. Roderigo’s emotions towards Desdemona build up inside of him and get the best of him. You will observe how Iago temps Roderigo to continue to pursue Desdemona’s love.
