'Game of Thrones' Star Nikolaj Coster-Waldau Explains Some Parts Of Jaime Lannister's Season 6 Story

"Game of Thrones" returned to HBO on Sunday night. It started the sixth season with Nikolaj Coster-Waldau's Jaime Lannister coming to the forefront. As he brought his dead daughter to King's Landing, fans expected Lena Headey's Cersei Lannister to slam Jaime. But the two of them did not quarrel.

Cersei instead went to Jaimie for some solace, remembering a prophecy that predicted her children's deaths. Jaime responded and promised vengeance.

"When someone you love is in pain, you want to do anything to comfort them," Coster-Waldau said. "And he kind of goes to that moment saying, 'Listen, it's you and me against the world. We can do this. We're going to fight back. We're going to take revenge.' Because he's never seen her this broken before. And now he wants her back. But, of course, he has no idea what's happened at King's Landing before, as we find out the whole power dynamic has changed. You have the religious uprising. It's a tricky situation."

However, Cersei and Jaime still have a strained relationship. As they have not been too cordial with each other, they have not been able to heal their wounds either.

"She hasn't been happy with him for a long time," he said. "I think, actually, since he came back with no right hand, she kind of lost a bit of interest in him. And I think now she needs him. And I think he is, for now, happy to step up. But she's not an easy lady to deal with."

Jaime feels responsible towards Cersei. Most of his family members are dying or disappearing, so he is upset.

"His father's gone, Tyrion's gone, he's all Cersei has now," Coster-Waldau said. "He has to deal with protecting their last kid, Tommen, who's also the king - who is a teenager in love, which is also not easy to deal with. It's hard to control him. So he has to deal with that. And first the biggest enemy here, of course, is the Faith Militant, this religious uprising, being spearheaded by the High Sparrow. He has to deal with him. That's what he's gonna do."

"Game of Thrones" airs Sundays at 9 p.m. ET on HBO.
