In Dormers hands, these characters are never just seductive scam artists.

NATALIE DORMER:Yeah, absolutely.

Absolutely [thats] how she portrays herself to him.

Its great; you see her thinking on her feet about tactics and how to handle him.

And he keeps moving constantly.

Thats the nature of his monster-like behavior, isnt it, the unpredictability of it.

So that was a little bit of a crossing over [between] life and art.

So [Margaerys] immediate reaction is shock and fear.

As an actor, whats it like to play a character whos also a great actor?

The saving grace with Margaery is not to overplay anything.

But for an actor, that kind of discipline is actually a very hard thing.

So all I can say is, its good to play her with conviction.

And Margaery loves him, shes very accepting of his sexuality.

I actually do think Margaery is a genuinely open-minded, very liberal human being in the way she thinks.

That was my first scene I ever shot, so I really did take it as my platform.

I see her as a very pragmatic, realistic human being.

Shes a calm, cool player, very much so.

I think Margaery is genuinely protective of Sansa.

She empathizes with her situation.

Its just good common sense.

Its very cynical to say that the PR with the orphans is just for show.

I dont think it is.

And that must be part of the reason Cersei sees her as such a threat.

Its utterly chilling when she explains The Rains of Castamere to Margaery.

She passes that first test, but God knows how many shes going to pass in the future.

Well, you may or may not know the answer have you read the books?

Are you aware of the story line going forward?

I havent read the books on purpose.

Ive chosen not to.

I know the broad strokes, the trajectory of what happens.

Dan [Weiss] and David [Benioff] are very good at surprising us all.

So there is still a great level of unpredictability.

Shes learning a lot about the principal characters of Kings Landing, and working out whos who.

Shes on a very steep learning curve.

I think its something shes been brought up trained, almost to be ready for.

So shes going to have to act out everything shes been trained for.

You didnt get to appear in the Red Wedding episode or this seasons finale.

How do you think Margaery responded to that game-changing event?

I hope that youll see it in the future, in season 4.

Something like the Red Wedding just goes to illustrate the darkness of Tywin Lannister.

I think the Lannisters are the only family that would have orchestrated [something like] that.

I mean,theseare the in-laws?
