Bit of trivia for the inquisitive sort - The lines hobgoblin says in the dream world in both routes are actually lines from Opedius Rex.
Creon: So what is it you want, Oedipus? To send me away from here?
Oedipus: Send you away? Absolutely not! I want you dead! Dead here, before me rather than alive elsewhere.
Creon: Tell me first. What exactly are you afraid that I will do to you?
Oedipus: And who taught you to utter these words? Surely you did not learn all this from your practice as a prophet?
Teiresias: Who? Why, it was you who taught them to me. It was you who has forced me to utter them.
Oedipus: What were the words again? Say them so that I know them even better.
Did you find any more easter eggs I've left in the dialogue? Let me know :)
