Sycorax: Who exactly are you?
Doctor: Well, that’s the question.
Sycorax: I demand to know who you are!
Doctor: I don’t know! See, there’s the thing. I’m the Doctor, but beyond that, I just don’t know. I literally do not know who I am. It’s all untested. Am I funny? Am I sarcastic? Sexy? Right old misery? Life and soul? Right handed? Left handed? A gambler? A fighter? A coward? A traitor? A liar? A nervous wreck? I mean, judging by the evidence, I’ve certainly got a gob.
