I disagree with some stuff said in the above. I actually feel Davos stuck in room with ghost and Jon's dead body and Melisandre sudden decision to take of her ruby and release the glamour is basically a setup for Jon Snow his resurrection. I'm biased in that I want Jon Snow to live but I really feel that way (that it's a setup for him to live). I mean why show Jon's Snow body being hauled to a secure room, why show that ghost is still safe and alive, why remind people that melisandre saw Jon in the battle for winterfell, why send for aid from Tormund when there's no one and therefore no real cause left to save (unless Davos becomes an even bigger hero), why show Melisandre at the end like that (to me it seemed like she was either giving up, or showing determination to do something after having made up her mind), why name the episode like that of not for Jon and Melisandre role in him coming back to life.
@Melisandre, apparantly some people already speculated before the show she was indeed an old woman using glamour to her advantage. I actually didn't see that coming, I felt like her ruby had special powers, but I didn't think Mel itself was that old. That said, it means that ruby is even more powerful than i believed, so if she intends to storage and fully harness it's power by releasing her own glamour to save Jon it could work.
Not too mention Jon and the north will now possible have a freed Sansa to rally behind. or Sansa is there to take over Jon torch...
There are a bunch of things i understood needed to be done, and with that i'm referring to the stuff in Dorne, but I feel it goes against what Dorne was supposedly all about, aka family. Because you want vengeance for your family, you start by killing your own family... . I get the weakness angle but still. I also found it interesting that this leaves Dorne without any legit martells in the show. Only the bastards are alive.
Meereen seemed so tiny when Tyrion and Varys took their stroll..., budget costs i guess.
As for Dany, seems part of untying her knot is going to the capital of the dothraki.
