"...I came, Oedipus, who knew nothing, and I stopped her. I solved the riddle by my wit alone."
"...It was fate that he should die victim at the hands of his own son"

"I have a deadly fear that the old seer had eyes. you'll show me one more thing"
after hearing about Jocosta's death, Oedipus could not handle his emotions by stabbing his eyes out because he could not control his emotions mentally. By doing so, he did not have to see anypain or crimes that have been done.
"O Oedipus, unhappy Oedipus! That is all I can call and the last thing that I shall ever call you."
Jocosta tells Oedipus that the last thing she will call him is unhappy. This foreshadows her death because that was the last time Oedipus was going to talk to her or see her alive before she takes her life.
"Shrieking out such things as: they will never see the crime I have committed or had done upon me!"
Although Teiresias is blind, Oedipus is learning that he is the one that is truly blind and unaware Oedipus begins to see that there is a possibility that he is the murderer, as he learns about the death of Laius, and realizes that Thebans have been blind to the truth the whole time.
