The Doctor: Allow me, sir, to introduce Miss Dodo Dupont, wizard of the ivory keys, and... er... Steven Regret, tenor. And lastly sir, your humble servant Doctor Caligari.
Masterson: Doctor Who?
The Doctor: Yes, quite right.
Even after all this time, he cannot understand.
I dare not change the course of history.
Well, at least I taught him to take some precautions. He did remember to look at the scanner before he opened the doors.
Now... they're all gone... all gone.
None of them... could understand. Not even... my little Susan... or Vicki. And as for Barbara and Chatterton... Chesterton. They were all too impatient to get back to their own time. And now, Steven.
Perhaps I should go home, back to my own planet... but I can't.
I can't.
Now, young woman, surely you wouldn't refuse me, Claudius Nero, a teeny-weeny kiss?
Vicki: But, Doctor, you don't even know your own name!
The Doctor: Oh, of course I do, my dear. It's... It's... It's...
The Doctor: No! No! No! No! Don't unplug it. You must never do that. You must never break the time and relative dimension link.
The Doctor: Quick. Use the force.
The Doctor: I learnt not to meddle in the affairs of other people years ago.
Tarron: Do you know anybody in the city?
Ian: Yes, I... I do know someone if I can find him.
Tarron: Who is he?
Ian: Who? He's a doctor.
Make no attempt to capture them. They are to be exterminated. You understand? Exterminated.
