COSTER-WALDAU I can understand why it’s hard for Jaime to talk about. Jaime’s always been ashamed of the fact that he did break his vow. It was his job to protect this guy. You would think that what he chose to do, to save the world, would be such an obvious thing, that it was the right thing to do. But still, in this world, it’s not. And he has to live with the fact. But Brienne understands. And he sees himself in her, in her dedication to others. She’s one of the few people he can trust.

What do you think their lives would be like if the fighting ended, if the battles were won, and if they could actually retire and live their lives in peace?

COSTER-WALDAU Well, I think that they’re both — I was going to say damaged people, but that’s wrong. They have history, and they carry that history with them, as we all do. Going into a relationship with someone who’s had a very long relationship with another woman, where they had three kids and lost those three kids in a very brutal way, and knowing that he has just left that woman, who is now pregnant with his baby … I mean, it’s not easy. It’s going to be complicated.

Do you think Brienne would mind if Cersei were pregnant?

CHRISTIE Yes!

COSTER-WALDAU No!

CHRISTIE She would.

COSTER-WALDAU You think she would?

CHRISTIE [Laughs.]

COSTER-WALDAU Well, then yes, she would.

CHRISTIE He had this intense sexual relationship with his sister, and then there’s this continuing relationship with Brienne. It’s a loaded relationship, and I don’t think it’s defined in either of their minds. But they know they enjoy seeing each other.

COSTER-WALDAU They clearly like each other.

CHRISTIE That’s not the way I’ve been playing it! [Laughs.] I think it actually hasn’t been overt. Nothing has been overt. If you take it from Season 2, when Jaime and Brienne first meet, through the duration of their history together, the changes in their dynamic — you watch it move from being repelled by each other, to respect, to being encouraged by each other, to possible attraction.
