The Doctor and Donna in “Partners in Crime”

With Martha, like I said, it got... complicated. And that was all my fault. I just want a mate.

You just want to mate?!

I just want a mate!

You're not mating with me, sunshine!

A mate! I want A mate!

Well, just as well, cos I'm not having any of that nonsense! You're just a long streak of nothing! Alien nothing!
