The Fourth Doctor, story by story - supplemental.
DOCTOR: I could be a curator. I’d be great at curating. I’d be the Great Curator. I could retire and do that. I could retire and be the curator of this place.
CURATOR: You know, I really think you might.
DOCTOR: I never forget a face.
CURATOR: I know you don’t. And in years to come, you might find yourself revisiting a few. But just the old favourites, eh?
CURATOR: You were curious about this painting, I think. I acquired it in remarkable circumstances. What do you make of the title?
DOCTOR: Which title? There’s two. No More or Gallifrey Falls.
CURATOR: Oh, you see, that’s where everybody’s wrong. It’s all one title. Gallifrey Falls No More. Now, what would you thing that means, eh?
DOCTOR: That Gallifrey didn’t fall. It worked. It’s still out there.
CURATOR: I’m only a humble curator. I’m sure I wouldn’t know.
DOCTOR: Then where is it?
CURATOR: Where is it indeed? Lost. Shush. Perhaps. Things do get lost, you know. And now you must excuse me. Oh, you have a lot to do.
DOCTOR: Do I?
DOCTOR: Is that what I’m supposed to do now? Go looking for Gallifrey?
CURATOR: Oh, it’s entirely up to you. Your choice, eh? I can only tell you what I would do. If I were you… Oh, if I were you! Oh, perhaps I was you, of course. Or perhaps you are me. Congratulations.
DOCTOR: Thank you very much.
CURATOR: Or perhaps it doesn’t matter either way. Who knows, eh? Who knows?
The Day of the Doctor - November 23rd, 2013.
Technically, this was not the Fourth Doctor, but an implied future Doctor who chose an ‘old favourite’ face for this incarnation. It’s still Tom, though, in all his gorgeous, nose-tapping, shushing, Fourth Doctorish wonderfulness!
