Doctor?

Hello, Amy.

Woah, woah, woah!

OK... Yes, she's sedated, that's all.

Half an hour, she'll be fine.

This is basically a sentry box. So headless wonder here was a sentry.

Probably got himself duffed up by the locals. Never underestimate a Celt.

Why leave a Cyberman on guard? Unless it's a Cyberthing in the box.

But why would they lock up one of their own?

OK, no, not a Cyberthing, but what, what?

Something big, something right slap in front of me, I can feel it!

Yeah, I think you probably are. I'll get it in a minute.

- Hello again. - Hello.

- How've you been? - Good. Yeah, good.

You didn't just die, you were never born at all, you never existed.

Erased? What does...that mean?

How can you be here?

I don't know.

Reverse thrust for compensatory stabilisation.

Daleks, Doctor.
