I'm talking about Arya, Catspaw, and the Night King's death.
First, (and I first made this post in the post-ep discussion if it looks like you're re-reading something) the religious factions all played a very specific role in killing the Night King.
- The many faced god produced assassin Arya.
- The Lord of Light revived Beric a million times over to save Arya. Mel told Arya point blank she's the one. Mel also confirmed that Beric was kept alive for this moment of saving Arya.
- The Seven saved Sandor Clegane, who saved Arya. Same as above.
- The drowned god via Theon, who "rose again harder and stronger," and protected Bran, bought Arya time.
- The old gods via the 3ER (Bran) gave Arya Catspaw.
Second, Catspaw's history is deeply tied with the first two books and seasons. Its the reason why the war of the five kings started, and it led to Arya's arc and every single other characters arc, culminating to that moment. It bridges the politics of Westeros we loved early in the series/books with the WW. Bran has echoed this idea a few times, and this seems to be a theme of the season: everything these characters have done has made them who they are and led them to this moment. In that way, its as if everyone played a role in the events leading to killing the Night King. The preceding seasons were not for nothing - they hardened these characters and filtered out the weak. Catspaw punctuates that.
Obviously Littlefinger has been dead for a season, but his influence is here. He started the war, but he also gave Bran Catspaw in s7. Tyrion actually was the original owner of this dagger. I'm sure there are many other things I'm missing that brought about this moment from other characters.
I guess the great irony is that if it weren't for the Catspaw assassin, humanity wouldn't have been distracted from the threat up north with these wars since 1998, yet its the reason why the NK is dead.
