The Doctor: So, you thought the Eater of Light could destroy a whole Roman army.
Kar: It did!
The Doctor: And a whole Roman army could weaken or kill the beast.
Kar: Yes.
The Doctor: Well, it didn’t work! You got a whole Roman legion slaughtered, and you made the deadliest creature on this planet very, very cross indeed. To protect a muddy little hillside, you doomed your whole world.

Nardole: We’re looking for Bill, right?
The Doctor: No, we’re looking for the maximum danger in the immediate area and walking right into it!

Listen, you are all very, very angry. And really, you’re just scared. But for now, would you mind awfully just jumping out of your skins and allowing Nardole and I to escape in the confusion?

Nardole [about a crow]: But it *talked*!
The Doctor: Well, of course it did. It’s a crow. All crows talk.
Nardole [taken aback]: Well, they don’t talk in the *future*!
The Doctor: Of course they do. Human beings just stopped having intelligent conversations with them, and they all took a bit of a huff.
Nardole: Crows in the future all in a huff?
The Doctor: Of course they are! Haven’t you noticed that noise they make? It’s like a mass sulk!

Five thousand Roman soldiers. Eyes peeled. They must have left some kind of mark on the landscape -- burning huts, slaughtered locals, sweetie wrappers.
