@JinxerBut parading JP around as Arya was an even worse plotline, especially since the whole thing that makes the North regionally special is that they're super loyal subjects. The Manderlys literally send a smuggler to an island of cannibals and unicorns o recover a kid they THINK might be there because Northerners are loyal as fuck to the Starks. Roose would have know this and never done the dumb "Th-this is Arya! She's going to marry my bastard son, so all you northerners mad that I betrayed the Starks should be happy now!"
The show developed Salsa into someone who could make decisions, she went from someone passively having bad things happen to her, to throwing herself into the face of danger in order to play the game-- as opposed to the books where literally all she does is sit around in the Vale because GRRM has too many characters doing too many things and some end up getting 'subtle plotlines' where their characters suffer.
@Lightning Fast It degrades post-season 3, but you may as well watch it because I do kinda doubt GRRM plans on finishing the series, especially since he is advising on the show. The show ending might be the only ending we get.
