The Face of Boe: I have grown tired with the universe, Doctor, but you have taught me to look at it anew.
Doctor: There are legends you know, saying that you're millions of years old.
The Face of Boe: There are? That would be impossible.
Doctor: Wouldn't it just? I got the impression... There was something you wanted to tell me...
The Face of Boe: A great secret.
Doctor: So the legend says.
The Face of Boe: It can wait.
Doctor: Oh, does it have to?
The Face of Boe: We shall meet again, Doctor, for the third time... For the last time... And the truth shall be told. Until that day...
[He teleports himself away.]
Doctor: That is enigmatic. That...that is...that is textbook enigmatic.
