Donna: You’re not saying much.
The Doctor: No, it’s just— It’s a funny old life. In the TARDIS.
Donna: You don’t want me.
The Doctor: I’m not saying that.
Donna: But you asked me. Would you rather be on your own?
The Doctor: No. Actually no. But. The last time, with Martha—like I said, it got complicated. And that was all my fault. I just want a mate.
Donna: You just want to mate?!
The Doctor: I just want a mate.
Donna: Well you’re not mating with me, sunshine!
The Doctor: A mate! I just want a mate.
Donna: Well it’s just as well, because I’m not having any of that nonense. I mean you’re just a long streak of… nothing! Alien nothing.
The Doctor: There we are then.
