Littlefinger wants the Iron Throne…and Sansa at his side
It wasn’t the most significant scene of the episode, but this interaction with Littlefinger and Sansa could possibly be setting up some strife between Sansa and Jon in the future. Littlefinger expressed to Sansa that he very much wants the Iron Throne for himself, and he’d like Sansa to be his queen. Sansa is quick to deny him that pleasure, but he replies with a sentiment of contempt for Jon. He says that Sansa should be the one to rule Winterfell and be the queen in the North, not Jon the bastard.
What does this mean for season 7?
It seems that Sansa doesn’t think much of this, until later in the episode when Jon’s supporters publicly pledge themselves to house Stark under his rule, and chant his name as “King in the North.” We can visibly see Sansa irked by this and share a look with Littlefinger, assuring the audience that this story isn’t over yet.
