In this TIME article it was mentioned that George R.R. Martin shared 3 major twists with the Game of Thrones showrunners:
Showrunners David Benioff and D.B. Weiss recently told Entertainment Weekly that during a 2013 meeting with Martin, they learned about “three holy sh— moments” the Song of Ice and Fire author intended to include in his series — two of which have already happened.
The first took place in the ninth episode of season five, when Stannis agreed to allow Melisandre to burn his daughter Shireen. The second was, of course, the revelation in Sunday’s episode that Bran Stark was the cause of both Hodor’s condition and death. And the third? Well, the third, “is from the very end,” Benioff told EW.
In S08E03, "The Long Night", the Night king is killed. Does this mean all 3 twists have been revealed? Do we know if the Night King's death was the last of the 3 twists?
