In 300 words or less, explain how the characterization of Creon and Oedipus in this section reflect the larger themes of the play.

A boy leads in the blind prophet Tiresias. Oedipus begs him to reveal who Laius's murderer is, but Tiresias answers only that he knows the truth but wishes he did not. Puzzled at first, then angry, Oedipus insists that Tiresias tell Thebes what he knows. Provoked by the anger and insults of Oedipus, Tiresias begins to hint at his knowledge. Finally, when Oedipus furiously accuses Tiresias of the murder, Tiresias tells Oedipus that Oedipus himself is the curse. Oedipus dares Tiresias to say it again, and so Tiresias calls Oedipus the murderer. The king criticizes Tiresias's powers wildly and insults his blindness, but Tiresias only responds that the insults will eventually be turned on Oedipus by all of Thebes. Driven into a fury by the accusation, Oedipus proceeds to concoct a story that Creon and Tiresias are conspiring to overthrow him.
