The Doctor, Cyberman 1 and others in “The Wheel in Space”

I suppose you've come for me?

You know our ways.

Yes, I hoped you realised somebody did. I imagine you have orders to destroy me?

Yes.

Tell me one thing, why did you order Duggan to destroy radio communication with the Earth? After all, that is why you want possession of the wheel, isn't it?

You know our ways.

That doesn't answer my question.

He was instructed to destroy only the transmitting complex.

Oh, I see, how interesting, yes, of course. And presumably your large space-ship holds your invasion fleet, and the smaller ships can only enter the planet's atmosphere by homing on a radio beam.

You know our ways. You must be destroyed.

Yes, I was afraid you'd get back to that.
