The City of Thebes is experiencing a plague and the people were pleading to Oedipus their king to save them from this crisis. because in the past he freed the city from the sphinx. He immediately asks Creon to ask Apollo what must they do to stop the plague.
Stop this unhappy men, the city is suffering yet you have the nerve to fight? Creon return home and you come inside.
What did lord Apollo said?
He said to capture the person behind the death of King Laius. The people said that it was a bandit however, no one knows him.
Bring Tiresias immediately!
The man entered the castle and as Oedipus asked if he knew the murderer, Tiresias provoked and didn't directly answered him. Oedipus became more angerier and angerier and accused Creon of plotting him by talking with this old man to bring him down and take over the throne.
How is that even possible?! Maybe you are the one who did it!
Oh, with your reaction it seems like you're the one responsible for the murder.
Oedipus rushingly accused Creon of setting him up with Tiresias because he wants to take the throne. Creon was shocked about how Oedipus said it without hesitation which made him angry. Both were fighting and throwing out words to each other when Jocasta came into the scene.
