Now that Ramsay Bolton and Walder Frey are dead, Game of Thrones showrunners David Benioff and Dan Weiss tell us more about the biggest villain in the world of ice and fire (The Night King) and why the most feared character in the show never speaks a word:
“We don’t think of The Night King as a villain as much as Death. He is not someone who’s like Joffrey or Ramsay. He’s not really human anymore. 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.
In some ways, it’s appropriate he doesn’t speak. What’s Death going to say? Anything would diminish him. He’s just a force of destruction. I don’t think we’ve ever been tempted to write dialogue for The Night King. Anything he said would be anticlimactic.”
