Adelaide, The Doctor and others in “The Waters of Mars”

[Pointing her gun at the Doctor] State your name, rank, and intention!

The Doctor. Doctor. Fun.

What the hell? It's a man. A man on Mars! How?

He was wearing this thing. (His orange spacesuit) I have never seen anything like it.

What did Mission Control say?

They're out of range for ten hours with the solar flares.

If we could cut the chat, everyone.

Actually, chat's second on my list, the first being gun pointed at my head. Which then puts my head second and chat third, I think. Gun, head, chat, yeah. I hate lists. But you could hurt someone with that thing. Just put it down.

Oh, you'd like that.

Can you find me someone who wouldn't?

Why should I trust you?

Because I give you my word. And forty million miles away from home, my word is all you've got.
