Fans have been long waiting for Jaime Lannister (Nikolaj Coster-Waldau) to leave Cersei Lannister (Lena Headey) and all her evil plans behind. Although it took him awhile to realize that her sister/lover is becoming a monstrous evil, the Kingslayer dumped her to honor his promise [VIDEO].

Jaime might be going up to the North in the coming Game of Thrones” Season 8 to join Jon Snow (Kit Harington) and Daenerys Targaryen (Emilia Clarke) battle the Great War. In an interview with Esquire, the 47-year-old actor opened up about that parting scene and his plan when he left Cersei.

The sudden realization

“Finally he saw what everyone else had been seeing … finally, he'd had enough,” Nikolaj Coster-Waldau told Esquire about Jaime dumping Cersei.

The “Oblivion” star explained that Jaime should always have to believe he is fighting for a reasonable battle. He can think that Daenerys and her people are trying to invade their country, take everything for them, and it could be true. Cersei might think that they are just defending themselves, but he actually saw how the Mad King is like and her sister is becoming like one. “Dragons are not nice animals,” he said.

And as he saw that the white walker is real, he now believes the danger coming, that Jon Snow, his brother Tyrion Lannister (Peter Dinklage), and Daenerys are saying the truth. However, when Cersei told her that they are going to hire new armies to fight for her instead of joining the Great War, he feels like everything is messed up. “It doesn't make sense,” he continued.

Nikolaj Coster-Waldau believes that it is morally wrong.

He also finally noticed that she didn’t respect him as a person, a counselor, her partner, and only consider him as her warrior.

The killing that didn’t happen

Nikolaj Coster-Waldau also talked about the last words Jaime told Cersei. "I don't believe you," the oathbreaker told the Queen of Westeros.

Although he was not surprised that Cersei wanted him dead, his words actually meant that he didn’t love her anymore and she was now on her own. Even though it took him awhile to realize it, he finally had enough.

Nikolaj Coster-Waldau believed that it was a miscommunication why The Mountain didn’t cut off his head. Maybe, Tywin Lannister's Mad Dog didn’t understand Cersei’s signal, or he didn’t get it at all. Cersei might still have feelings for him and still in denial of what she was seeing. “She's stunned at what's going on,” he said. Jaime had done everything to protect her and keep their incestuous relationship alive. Thus there was a moment of disbelief that he was actually walking away from her.
