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.
