What attracts Jaime to Brienne? Why does he trust her?
She has proven herself from the first scene they had together in the end of Season 2 when she kills the Stark men. He did not expect that. She's demonstrated that she's a very capable fighter and she's clearly a woman of her word. She lives by a code that Jaime also believes, but he's become a very cynical person. He's learned that all these beautiful words like "honor" and "dignity" don't mean anything in this world. Then he meets someone who says, "Well, I don't care because that's how I am. I have to stand up for what I believe is right." Which is what Brienne does, she reaffirms there's a place for dignity... I think it reawakens something inside of him. He just knows she can be trusted, it's instinctual.
Is that why he tells her the truth about killing the Mad King?
I think he's been dying to get it out, but he's never met anyone where he's felt that it would make sense. I'm sure he would want to tell Tyrion, but his brother is very cynical. For someone to open up, there has to be room for it. In a weird way, Brienne gives him that space that no one else does.
What compels Jaime to jump into the pit with the bear?
I think it's pure instinct, and it's really stupid because the odds are they're both going to get killed. But there are so many layers why it's wrong, he acts. He just can't stand that a woman that has so much dignity should be degraded that way—given a wooden sword while everyone's just standing there watching.
What was it like filming that scene?
Oh, it took a long time. We shot it twice. In October last year we shot in Belfast with the crowd and the wire work involved with getting out of the pit. Then in January we went to California and we shot it with Bart the Bear II. What you see in the scene is a real bear—it's not a CGI thing, it's a live bear, an actor, kind of a diva I have to say... They built half the pit on a soundstage, and we shot Bart's close-ups, if you will.
