Same as other stated before me, despite the season being weak overall, I feel this episode fits well as a "finale".
Those saying nothing has changed are being a bit harsh I think, the sole fact that kings will now be elected is an actual big game changer in the long run. Obviously we cant see it in this episode cause not nearly enough time has passed but on paper, it means that the ruling family will plot less for the weel being of their kin, and more for the good of the realm. That's an ideal scenario of course.
The only thing that really bothers me is Jon going back to the Night's Watch. There shouldnt be a need for it anymore, as now the relationship with the wildlings is supposedly better. Being sent to the Wall is basically "go be bored your whole life".
I guess this too can be changed in the near future, as at the moment of the show people are still stuck in their old way of seeing the world.
Arya going to the West is a potential seed for a spin-off Im guessing.
