A Theory

The following is a theory for HBO's Game of Thrones..  Potential spoilers ahead.

If you watch Game of Thrones you know that Sansa has escaped the all but mustache twirling villain Ramsay Bolton. She has fled north to the wall and met up with her half brother Jon Snow.

In last weeks episode she got a raven from Littlefinger and she secretly meets him.  For a time Sansa seemed to have the upper hand and Littlefinger seemed to be dancing in discomfort. While I don't think he wanted what happened to Sansa happen he is still playing The Game. While Sansa has grown up and is no longer a passive piece in The Game she is still inexperienced and Baelish has been at it for a lot longer. He also knows more about what is going on than she does.

At this point Baelish knows that Sansa is fairly well guarded and so long as the She-Hulk Brienne is with her Sansa is all but untouchable. So he's told her something important - her uncle the Blackfish has retaken Riverrun and has an army of two thousand men. He tells this to her towards the end as almost an after thought.

If he is being honest then Sansa has family and an army to call upon to help retake Winterfell. Baelish has shown honesty and she might forgive him.

If he's false he can spin it that he had been given misinformation and his situation is more precarious. Either way he knows Sansa and knows that she would not send a raven with a message to the Blackfish on the off chance it gets intercepted. She would send her most loyal retainer - Brienne of Tarth. That will leave Sansa vulnerable and Littlefinger never lets a situation go to waste.

Baelish still has his long game and somewhere Sansa plays into it. Once Winterfell has been retaken he may seek to marry her to become lord of Winterfell. A lot will have to happen for that everyone, including Sansa, are merely pieces for Baelish to move on the board of The Game.
