[Maximo]

I'm going to watch the last 2 episodes again and pay closer attention to Sansa. Still leaning toward her being duplicitous. At the Wall, she tells Jon that they have to save Rickon and recapture Winterfell no matter what the odds.

Then the night before the battle, she tells Jon that saving Rickon is hopeless and Jon doesn't have enough men. No hint that she had written to Littlefinger.

I think she is hardened and playing the Game of Thrones.
