It's over. Yet another season of "Game of Thrones" has come and gone. Ten episodes simply aren't enough. It seems like yesterday that the third season premiere had fans electrified with the prospect of spring full of clashing swords, fire breathing dragons and conniving kings, but as life is, all good things must come to an end. Luckily for diehards however, there's still plenty to chew on while they wait for the show's return.

In an interview with Esquire, Nikolaj Coster-Waldau, who plays Jaime Lannister, otherwise known as the King Slayer, opens up about his character and what life is like working on "Game of Thrones."

"The biggest secret he's been carrying for so many years - the truth of what happened when he killed The Mad King - to finally get that off his chest was a great scene to do," Coster-Waldau said about how his character has evolved in the past three seasons. "He started out doing this hideous thing to Bran [Stark], trying to kill Bran, and now you see him saving Brienne of Tarth a couple of times."

In the forthcoming season, Jaime will have to adapt with only one hand. In season 3, Jaime attempted to use his powerful father's name to get him out of a hairy situation, a decision that prompted his captors to cut off his right hand in order to teach him a lesson. The scene took two full nights to shoot.

"The first night we did all the dialogue, thank God," he said. "The second night I was very sick and I wasn't sure I was going to be able to shoot that night. But it actually fitted the moment quite well. I was a little out of it."

"Even when you did it and it was clear my hand didn't come off, there's something about being held down and him lifting his arm up with a knife and going full force down on you... it's very scary."

And what about next season? "Of course I know a few things about what's going to happen," he said. "He is a changed man... Everything is about how to fit in with Cersei's life and how to fit in with his father's expectation. Who knows? I hope that he will become his own. It's difficult in that family."
