Meh. Sansa just feels like a internal strife device to me right now. "Oh, you think Cersei's coming? How naive." "We didn't store enough food for all these armies!" "She needs to earn the respect of the north!"
Very meh. No shit, you don't have enough food. Guess what? You won't need much food in two days when at least half of your army is decimated. You're not housing these armies for a year, you're housing them for a few days. The Night King is already on the march and you were aware of this when you were complaining. She needs to earn the respect of the north? Dude, this chick, by her own declaration, believes she's in the right to declare war on you and kill you all. And yet, she's here pledging her armies to your cause to prevent you from getting overrun by hundreds of thousands of undead. Again, in two days she's going to be earning the respect that you're bitching about.
I don't actually dislike Sansa as a character, and I think her character development is fine, but some of this writing has got me pretty salty.
