The Doctor: The TARDIS.
Donna: What?
The Doctor: The TARDIS!
Donna: The what?
The Doctor: It's called the TARDIS!

The Doctor: Well it is for me.
Donna: You're an alien.
The Doctor: Yeah.

Donna: No stupid martian is going to stop me from getting married!
The Doctor: I'm not... I'm not... I'm not from Mars.

Donna: What did you do?
The Doctor: Something... martian.

The Doctor: With this ring, I thee bio-damp.
Donna: For better or for worse.

The Doctor: Great big spaceship? Hopping over London? You didn't notice?
Donna: I had a bit of a hangover.

The Doctor: You're not special, you're not important...
Donna: This friend of yours, just before she left, did she punch you in the face? Stop bleeping me!

Donna: Enough of my CV. C'mon, it's time to face the consequences. You can do the explaining, martian boy.
The Doctor: Yeah, I'm not from Mars.

The Doctor: Christmas trees.
Donna: What about them?
The Doctor: They kill.

The Doctor: What's that?
Donna: We've drained the Thames.

Donna: I've gotten married, lost my job and become a widow on the same day.

The Doctor: I don't need anyone.
Donna: Yes you do. Because sometimes you need someone to stop you.
