(The regeneration effect comes to an end. The new DOCTOR blinks and shakes his head.)
COMPANION: What...what happened?
DOCTOR: Oh. Hello. Weren't you watching? Well, I'm sorry, I'm not doing it again. Not for a while at any rate.
COMPANION: You look...older.
DOCTOR: I am older. I've aged...oh, thirty-seven seconds.
COMPANION: I mean...much older.
DOCTOR: Age is irrelevant. If I wore my mind on the outside and my body on the inside, you'd see a very old man indeed. One can't prance about being young forever. Anyway, I think a certain degree of maturity is no bad thing. It lends dignity and-- (He catches sight of himself in a mirror) Oh. Oh dear. Well, I wasn't thinking of that much maturity exactly. Still, what's done is done.
COMPANION: And you sound different too. More...posh.
DOCTOR: I suppose you have met me, have you? Time Lord? My people invented “posh.” We were the original aristocrats of the universe. Fat lot of good it did us in the end, of course, but I'm rather over being ashamed of my background. More irrelevancy. What matters is the now. (He moves towards COMPANION, who shrinks away) Is there a problem?
COMPANION: Yes. No. I'm not sure.
DOCTOR: So suddenly I'm too old and too posh for you, is that it? It was all very well when I was the gurning adolescent in the demob suit, but now I look more like my real age and sound more like my real self you start to realise who I am. I was always too old and too posh. And you knew it. (He moves away again.) I blame myself. Or my previous selves anyway. Mid-life crisis...desperate attempt to recapture lost youth...inappropriate relationships with younger women...and having your home planet expunged from the cosmic time stream doesn't help. Well, it's well past time I got a grip. Put some distance between me and...others. Getting too involved helps nobody. (Looks down at clothes) I'm going to go and get changed. While I'm doing that, you can decide if you want to carry on travelling with me. If not, I'll drop you off somewhere.
(At which point the episode supervenes.)
