He refutes the rumors and instead chooses to defend his mother against his better judgment. It then shifts to a private conversation between Clytemnestra and Aegisthus inside the house. Aegisthus continues to seduce Clytemnestra with his swaying words. She has been lonely and patiently waiting for her husband but with no news after 10 years of waiting, she eventually and regrettably fell for Aegisthus. Together they decide that it will be Clytemnestra that will kill him by using her trust. Orestes then enters the room and tells his mother that his father is arriving and that he is going to greet him upon arrival. It's at this moment with his excitement and joy that Clytemnestra starts to ponder whether or not to go through with the killing Agamemnon and causing pain to her children and family. As Agamemnon arrives at the port, he is greeted by Orestes and Electra who are both excited to welcome their father who is now a hero of the war in Troy. .
They greet each other and Orestes starts explaining about everything has happened since his time away. He does, however, choose not to tell his father about the rumors that Aegisthus and his mother have been having an illicit relationship. He does so believing and hoping that his family can live and stay together. During this the chorus are talking to each other again about if Agamemnon finds out that his wife has been disloyal, they fear that it will have tremendous consequences. We shift back to Clytemnestra as she waits for the arrival of her husband and their children. She begins to ponder about why and how she has gotten to this point where she is about to kill her husband and betray her family. It's at this moment that she starts to doubt herself once more, only for Aegisthus to arrive and seduce her as he has been doing for many years. When Agamemnon finally does arrive with Orestes and Electra, he is greeted as a hero should be with a great party and feast in his honor.
