I would be disappointed if she ever teamed up with Littlefinger again for anything. She might end up being Queen of Winterfell, with Jon Co-ruling with Daenerys. I still expect Littlefinger to get dispatched in a future episode. To me Jon would be a very capable and wise leader. I hope I’m not disappointed.
I hope you’re right, but remember. Littlefinger did school her on the strategy needed to play (and to succeed in) the Game of Thrones.
She was raised to wed a powerful man. She expected to be Joffrey’s (ewww) Queen and to rule Westeros. She stated that that was her greatest goal.
She was raised to hold Jon as beneath her. She watched her mother’s attitude toward him. She admitted she treated him horribly when they were younger.
Sansa did promise Littlefinger that if he brought the knights of the Vale he would be rewarded. She didn’t specify how he would be rewarded, but she just seems to be dissing him now.
