Legend of the Sea Devils

DOCTOR: Yaz, I can't fix myself to anything, anywhere or anyone. I've never been able to. That's what my life is.

YASMIN: Yeah, of course.

DOCTOR: Not because I don't want to, because I might. But if I do fix myself to somebody I know, sooner or later, it'll hurt.

YASMIN: Make a wish and skim it.

DOCTOR: I wish...

YASMIN: You can't say your wish out loud!

DOCTOR: You can where I'm from. I wish... I wish this would go on forever.

DAN: Has she said something to you?

YASMIN: Why? What would she say to me?

DAN: Oh, come on, Yaz. Can't you see it?

DOCTOR: Wow. Isn't it spectacular? What a universe. What a planet. Just when you think you've seen the lot there's something like this.

YASMIN: It's stunning.

DOCTOR: Yes, it is. Not a bad date, am I?

“You know what I said earlier about not being a bad date? Well, dates are not something I really do, you know. I mean, I used to. Have done. And if I was going to, believe me, it'd be with you. I think you're one of the greatest people I've ever known.”

DOCTOR: Come on, tell me you're impressed.

YASMIN: Oh, you're like a kid sometimes.

DOCTOR: Thanks! What, only sometimes?

DOCTOR: But the point is, if it was going to be anyone, it'd be you. But I can't.

YASMIN: Why not?

DOCTOR: Because at some point time always runs out.

DOCTOR: I'm going to find out what he's up to, and then I'll dazzle you with a beautiful bit of improvisation.

YASMIN: You mean there's no plan.

DOCTOR: Early days.

DOCTOR: You really pimped his ride! Do people still say that?

YASMIN: It's 1807.

DOCTOR: I'm ahead of the curve.
