Fifth Doctor: I'm the Doctor, who are you?
Tenth Doctor: Yes you are! You are the Doctor!

Fifth Doctor: Who are you?
Tenth Doctor: Take a look.
Fifth Doctor: Oh. Oh no...
Tenth Doctor: Oh yes!
Fifth Doctor: You're... oh no!
Tenth Doctor: Here it comes! Yep, yeah, I am -
Fifth Doctor: ...a fan!
Tenth Doctor: Yeah. ... What!?

Fifth Doctor: To days to come!
Tenth Doctor: All my love to long ago.

Tenth Doctor: You know, I loved being you. Back when I first started at the very beginning, I was always trying to be old and grumpy and important, like you do when you're young - and then I was you. And I was all dashing about and playing cricket and my voice going all squeaky when I shout, and I still do that, the voice thing, I got that from you! Oh, and the trainers and... Snap! Because you know what, Doctor? You were my Doctor!

Tenth Doctor: Oh brilliant! I mean, totally wrong, big emergency, universe goes bang in five minutes but... brilliant!
