Was so much better on TV. Now that the episode has aired, it's safe to openly post about it. It all makes sense now as to why the Night King has been taking his time. He obviously saw this happen with his Greenseeing and was awaiting the opportunity to capture a Dragon. I imagine this is how he breaks the wall now.
Jon bending the knee and suddenly falling in love sucks and is out of character, but tbh the Northern Lords are snakey twats anyway and don't deserve a King like Jon and the Scene was nice. Night King and a Dragon = Game Over. He took Viserion down with ease and would probably to the same to the others. Bran is our last hope and Saviour.
Oh and shouts to Uncle Benjen. What a man. Our true protector until the very end.
