The Doctor: Oh, don't do that. You look like you're self-concussing. Which would explain all of military history, now I think about it.

The Doctor: You know where it is.
Missy: Yep. You know the best part about knowing? Not telling you.

Osgood: Who is she?
The Doctor: You'd never believe me if I told you.
