'No One but Azor Ahai can kill the Night King, if the Night King stops Azor Ahai Reborn from killing him, then No One will'
There. Are. Spoilers. Here.
Now that the
Battle of Winterfell is over, it appears that the focus of the remaining three episodes will be firmly on the war for the Iron Throne as Cersei Lannister faces the combined threat of Jon Snow and Daenerys Targaryen.
Granted, that alliance is currently on shaky ground after Dany discovered that 1) Jon is the true heir to the Iron Throne, 2) he's her biological nephew, but it seems that after the recent war against the dead in The North, the attention will now shift to King's Landing.
However, as soon as Arya Stark delivered the fatal blow to the Night King in the Winterfell Godswood, fans of the show had questions. Questions that one Redditor has sought to answer with a fan theory arguing that the The Long Night "makes perfect sense."
Buckle up.
The thesis: Only someone unknown to the Night King will be able to kill him. Big NK is aware the only way to defeat the dead is to kill him, he wouldn't allow that to happen by risking his safety. He parks Viserion outside the Gods' Wood, he only intervenes in the battle when dragons are torching his dead bois to death and opts to surround Jon Snow with wights rather than face him in single combat.
The Night King has never seen Arya Stark. She is no one to him. During her time with the Faceless Men Arya trained to become "no one."
No one can kill the Night King other than Azor Ahai, and if Azhor Ahai reborn does not kill him, no one will. No one did.
[Spoilers]Why The Long Night Episode makes perfect sense. from r/gameofthrones
The key passage: "This is why Jaquen gave Arya that coin, not to turn her into some faceless assassin to kill Cersei, it's why they trained her, it's her entire purpose. Stop he who has cheated death with magic. Who has stolen from the God of Death over and over, whose very existence is an affront to death, because he is undying, and he robs the many faced god. put right that which the others have wronged."
See? "Perfect sense."
