The Doctor: Yes, you're right, if we lie to her she'll get all
better.
The Doctor: Amy, you need to start trusting me, it's never been more
important.
Amy Pond: But you don't always tell me the truth.
The Doctor: If I always told you the truth I wouldn't need you to
trust me.
The Doctor: River Song, I could bloody kiss you!
River Song: Maybe when you're older.
Amy Pond: It made me think about what I want. Who I want. You know
what I mean?
The Doctor: Yeah. [beat] No.
Amy Pond: About who I want.
The Doctor: Oh right, yes. [beat] No, still not getting it.
Amy Pond: Doctor, In a word, in a very simple word, even you can
understand.
The Doctor: Amy, I am nine hundred and seven years old, do you
know what that means?
Amy Pond: It's been a while?
The Doctor: Ye... No! No! NO! I'm 907 years old and look at me. I
don't get older, I just change. You get older. And I don't. And this can't ever
work.
Amy Pond: Aw, you are sweet, Doctor, but I wasn't looking for
anything so long term.
The Doctor: I'll do a thing
River Song: What thing?
The Doctor: I don't know it's a thing in progress, respect the thing
