'Game of Thrones' Season 7 spoilers, air date: Lena Headey's Cersei could be a force to reckon with

Season 7 of HBO's "Game of Thrones" is yet to have an air date and the plot for the upcoming season is also a complete mystery, as the show has now completely diverged from its source material, George R R Martin's "A Song of Ice and Fire."

But something that both fans of the book as well as the television show will agree is that the Night King is a force to reckon with. That does not mean he is a villain, says showrunners David Benioff and D.B. Weiss.

"We don't think of The Night King as a villain as much as Death," the duo told Deadline, adding that he isn't someone like some other cruel and heartless characters such as Joffrey and Ramsay. "Evil comes when you have a choice between that and good, and you choose the wrong way. The Night King doesn't have a choice; he was created in that way, and that's what he is. In some ways, he's just Death, coming for everyone in the story, and for all of us...."

According to the showrunners, one of the things that will be explored in the next season is Cersei's mindset and what she'll set out to do now that she has been crowned the Queen. The look that was exchanged between Cersei and her twin Jaime could be interpreted as the Kingslayer finally conceding to his sister's authority, believes Benioff and Weiss.

"Cersei has certainly done a lot of horrible things in her life and she could be a very cruel person, but the one thing that was redemptive about her was she genuinely loved her children. Now they're all gone, and I think that is very interesting for us. Who is she, without her children? The answer is something you'll find out about next season," they added.

"Game of Thrones" is expected to air sometime in the second half of 2017.
