Ultimately, what he is doing is making Arya flip out on Sansa, which will make Sansa distrust Arya. He can't more directly try to turn Sansa against Arya because Sansa doesn't particularly trust him.

Jon Snow hung a child.

I think Sansa is the one who is most concerned with the survival of her subjects, so far she is the only person who has enough food for the winter for all of her people, which Jon didn't bother to think to do because he is a "big picture" leader who never thinks of things like that.

People wouldn't accept The Kingslayer as a King anyway.

That seems like a stretch, if your kidnapper says "We're getting married", what do you say?

Rhaegar was already married. He took Lyanna to Dorne, and had his marriage annulled, and then had a wedding with Lyanna.

But not information which was useful to stopping the White Walkers, which is all that he wants.

It well help that the closest thing to an heir to the house is loyal to Jon Snow.

She doesn't force people to serve her, but she does force people to accept / acknowledge that she is the ruler (whatever their culture's specific world for ruler is).

He will probably live to see either Tyrion or Bronn again in some capacity, but you're right that I forgot him.

I'm not sure about that. They didn't show her paying the guy yet. It doesn't really make sense for the Bank to take the money and then immediately lend her more money (to what end? Nobody else on the continent has any money, so how will this war earn her enough money to pay them back plus interest?), and it doesn't…

That scene was so tense because Bronn is on a very short list of characters who are still around who the show could kill off in a scene like that. Brienne, Jorah, Bronn, Edd and one of the lesser two dragons, these seem like the characters who can still die in big battle scenes, most of the rest have specific…

She is loyal to her own people first and foremost, and if he doesn't bend the knee, they aren't her people.

The magic doesn't require her to kill somebody to wear their face, that's clearly established by (1) her wearing faces of people she didn't kill and (2) multiple people wearing the same face.

If poison worked on dragons, wouldn't dragons have always been a lot easier to kill?

Now I am definitely convinced that Arya will kill Littlefinger while disguised as Ned Stark. If so, good job show for shooting a secret Sean Bean cameo while the Internet focused on Gendry.

Part of the theory is that the show has been pretty vague about how the face magic works, so her using Ned's face wouldn't break any explicit rule, and it would be too cool a moment for anybody to complain. (A friend of mine posited, in response to this, that it could be case where Arya can do it because she knows…

The Westeros plotline takes a week, the navy plotline takes a day, and the dragon plotline takes an hour.

Yeah, but she's gonna kill Littlefinger, so she has to go to Winterfell.

That quote is from Peter Gould, not Vince Gilligan. The reason he would phrase it like that is that he is talking about the ideal audience reaction to the last moment, that they see she is okay and then start to think "Why did that happen?" and look back on this episode, and previous episodes, and understand why it…
