When George R.R. Martin, author of the A Song of Ice and Fire series, told Game of Thrones showrunners David Benioff and D.B. Weiss how the saga was going to end, they described their reaction as a series of three "holy shit" moments.
Two of them have already happened.
In an interview with Entertainment Weekly, Benioff and Weiss said that they had a meeting with Martin two years ago in Santa Fe, where the author provided them with a rough sketch of how the series was going to end.
Warning: The rest of the post will contain spoilers for major events that have happened on the show.
The first major twist was that Stannis Baratheon sacrificed his daughter Shireen — which was shown during the fifth season — and the second was a scene depicting how Hodor got his name. The third moment, however, won't happen until the very end of the series, according to Benioff, but it is the biggest and most important of them all.
Still, despite the necessary inclusion of the third twist, Benioff said the books won't be too spoiled by the remaining seasons. He added that the show, much like The Walking Dead, has diverged quite a bit from what's happening in the books, but admitted there were a few unavoidable areas.
Game of Thrones is currently in its sixth season, with Benioff and Weiss making plans to end it after the eighth. According to the showrunners, the final two seasons will be condensed into a total of 13 episodes instead of 10 each season.
