Why does Oedipus think Jocasta is upset when talking to the Messenger?

Oedipus misinterprets Jocasta's distress during the conversation with the Messenger, thinking she is upset possibly due to his perceived lower status. This misunderstanding highlights Oedipus's character traits, such as his arrogance and inability to see beyond his own perspective. Jocasta’s reaction is actually rooted in her awareness of the terrible truth surrounding Oedipus's identity, which he remains oblivious to at that moment.

In this context, the misunderstanding reinforces the theme of fate versus free will, as Oedipus continues to deny the implications of the prophecy that haunts him. Rather than recognizing the genuine source of her anxiety, Oedipus allows his assumptions about social hierarchies to cloud his judgment. This lack of insight into Jocasta’s true concerns contributes to the dramatic irony of the play, as the audience is acutely aware of the tragic fate awaiting them, while Oedipus remains blind to it.
