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.
Littlefinger is going to die even if I have to yell at the writers to make a cameo role for Enterprise to enter the act to do it myself!
