tragic hero

Jocasta is describing King Laius to Oedipus without knowing that he is his son. (815). She actually realizes and says they look alike and has a similar build. It's dramatic irony because little does she know they're father&son. Then Oedipus starts to put things together realizing he might be the murderer of King Laius. (820). this is very tragic because he is trying to be a good guy and do the best for his people, and bring Laius's death to justice only to find out he is the killer. It's even more tragic that he is already devastated but he still has no idea about his mother&son relationship with Jocasta. Later he fears the prophecy about killing his father and marrying his mother, he ran away from home in the first place because he was trying to avoid it, bu the messenger tells him he has nothing to worry about.(1110). The messenger doesnt know that he isnt aware of his birth story and explains to him that its fate that he'd kill his father and marry his mother.
