Haimon, Creon's last remaining son, arrives and Creon asks if he is here because he hates him or because he understands why he's doing it. Haimon responds, telling him that he is loyal to his father. They talk back and forth and begin fighting, Creon saying that Haimon is blinded by love and Haimon saying that Creon is blinded by power; the people dislike his decision and that his father is ruling for himself and not the state. Haimon says that his father will never see his face again and leaves. Creon decides to lock Antigone in a vault far away, feed her, and let her do what she'll do (kill herself).
Then she must die. ––But her death will cause another.
You’ll never marry her while she lives.
Choragos begins to dislike the fate of Antigone, Antigone explains that she is being sentenced for nothing and her death is near, the chorus meanwhile praises her for her actions. Creon orders her to be taken to the vault and states that her death is in her hands (his hands are clean). Antigone once again explains that she is dying before her time for burying her brother. She then tells the guards that she would like to leave.
"If dirges and planned lamentations could put of death, men would be singing for ever. " (Sophocles IV.708-9)
Teiresias tells Creon that he would do well to listen to him; without him, Creon would not be in power. Teiresias then explains that the gods are angry and Creon, alone, brought this upon everyone. He explains that everyone makes mistakes but good men stop when they realize it and that the only crime is pride. He explains that Creon should be able to stop if it benefits him, and he begs him to stop. After Creon disregards what he said, Teiresias says that Creon will pay for his actions corpse for corpse, flesh of his own flesh. Creon is troubled by the prophet and goes to the tomb to set Antigone free.
Let him waste his fine anger upon younger men, maybe he will learn at last to control a wiser tongue in a better head.
A messenger arrives and is hinting at sorrow which Choragos questions. The messenger tells him that Haimon killed himself, driven mad by the murder Creon committed. Creon's wife joins them and the Messanger tells them the story: Creon went to burry Polyneicesbut his body was shredded by nature. They buried him and then ran to the vault where they saw Antigone hanging in a noose. Haimon was distraught and after Creon tried to comfort him, tears rushing in his eyes, Haimon spat in his face and drew his sword. He tried to stab Creon but missed and, in desperation, stabbed himself. As he died, he gathered Antigone close in his arms.
Eurdice (Creon's wife) left without a word and the messenger followed her into the palace. Creon arrives, carrying his dead son, and explains that he was a fool. The messenger then comes from the palace and tells them that the Queen is now also dead; she stabbed herself with a dagger and her last words were cursing Creon. Creon is in agony at the loss of his wife and son and wishes he were dead. Creon finally understands that he is guilty for all of their deaths.
