If you look at what’s happening in King’s Landing, it seems like Jaime’s gotten everything he wants. They’re in charge, they can be open about their relationship, they can be open about their new child. But in the scene where Cersei tells him she’s pregnant, it’s so deeply unpleasant to watch them interact.

It was very unpleasant. You know this is not a good situation. I mean, I don’t think these people should have any more children!

Jaime knows that this is not necessarily great as well. But if this dream is the one thing you want more than anything your whole life, you can’t help yourself. He experienced it for a second with Myrcella — what it felt like to be a father and have his daughter tell him that she’s happy that he was her dad — but it was taken away from him the second after. Now, the idea that you don’t have to live a lie, you can have a son or daughter and this can be beautiful, he forgets the reality of their situation and he’s happy.

But only for a second. After that, Cersei has to go all Darth Vader and say, “Don’t ever betray me again.” Which is dark. It doesn’t make sense, because he didn’t betray her. He actually came to her and told her about it as soon as he got back. But maybe that’s just because she’s paranoid.

Jaime’s certainly aware of the dangers in both Daenerys and Cersei, and his formative experience as a young man was murdering a king to stop him from burning thousands of innocent people to death. Things haven’t quite gotten to that point, but he’s got to be reliving that, right?

I think there’s a difference between the Mad King and Cersei. What Cersei did was a lot more specific and calculated, and it was aimed at her enemies. The Mad King was just going to take out everyone, and he felt he was going to be able to rise from the ashes as Daenerys did. When Cersei killed the Tyrells and the High Sparrow, it was very gruesome, tough thing she did, but it was very Red Wedding–style. She took out the people who wanted her dead, and she took them out in one ball of flames, but she didn’t take out the whole city. So there is a difference. I’m not justifying it, but I’m saying there’s a difference.

I think that what Jaime just witnessed with Daenerys is more than frightening. He knows that if she goes to King’s Landing with three dragons, when he’s seen what she does with only one, that will be the end of it. He knows that there is no way that they can fight back, or at least they’d need a hundred scorpions. It would just be very difficult.

I was thrilled to speak with Nikolaj Coster-Waldau about Jaime Lannister for the first time in many years for Vulture. He and I also talked about his new prison movie, Shot Caller, which is worth a look.
