See what Game of Thrones showrunners Benioff and Weiss have to say about one of the season 3 episodes they wrote themselves, titled “Second Sons.”

In this episode of Game of Thrones, Tyrion and Sansa got married at King’s Landing. In Yunkai, Daenerys met with the Second Sons, and seemed to win the allegiance of Daario Naharis.

This “Inside the Episode” video explores some of the episode’s key developments, and showrunners D.B. Weiss and David Benioff explain the character motivations behind them:

The first scene they discuss is the one where Davos Seaworth appeals to Stannis’ conscience, trying to stop him killing Gendry.

Benioff explains that Stannis has really come to rely on Davos’ council because despite the fact that he seems blindly devoted to his king, he will always answer him honestly.

“Stannis is a smart man; he recognises that Melisandre has her own agenda,” he says, “she’s serving this Lord of Light, she’s a religious fanatic … he’s just not a fanatic.”

Weiss adds that he’s not willing to take the leap from seeing the proof of her power to believing in her One True God.

Next is the epic scene after Tyrion and Sansa’s wedding, where Tyrion verbally impslaps Joffrey for his lewd suggestions.

“Joffrey can’t abine anybody knowing who he really is,” Weiss explains, and this is why he started hating Sansa when she witnessed his humiliation at Arya’s hand in the first season of Game of Thrones.

Benioff explains that Tyrion is conflicted about this whole situation, because while Tywin is expecting him to produce an heir, he realises that Sansa is much too young and that she really doesn’t want to be with him.

“Despite the fact that he’s somewhat attracted to her, he’s a proud man, and he would hate himself in the morning if he made her do this thing,” Benioff says.

Game of Thrones is off for a week, and season 3, episode 9 “The Rains of Castamere” will air the Sunday after next at 9/8c on HBO.
