Hey,
I agree with most of this. I especially love the reference to Chekov’s Tongue! Bravo (tips cap).
My only slight pushback is about Brienne. I tend to take the perspective of the books as slightly more important to the “real” character logic and in the books Brienne is a legitimate badass sword fighter and one of the best in the world (too many examples to count).
The rest is well put and reasoned! Always a pleasure!
