Egeus s is angry because Hermia won't marry Demetrius. He asked Theseus if he can exercise his right as a father to execute his daughter if she doesn't obey.
Thanks, good Egeus. What's the news with thee?
Happy be Theseus, our renowned duke.
Come I with complaint against my child Hermia. -Stand forth, Demetrius.- This man hath my consent to marry her.-Sand forth, Lysander.- This man hath bewithced my daughter.
-And, my gracious duke, if she won't agree to marry Demetrius now, I ask you to let me exercise the right that all fathers have in Athens. I can either make her marry Demetrius- or have her killed.
What say you, Hermia? Be advised, fair maid: to you your father should be as a god,to whom you are but as a form of wax, by him imprinted and within his power to leave or disfigure it. Demetrius is a worthy gentlemen.
