Sometimes, fans are too smart for their own good.

A popular fan theory for season five of HBO's "Game of Thrones" has been making the rounds, and the show's most recent trailer may have confirmed it. In the fifth novel, "A Dance With Dragons," readers witness Ramsay Bolton marry a girl named Jeyne Pool who is posing as Arya Stark (remember, no one knows where Arya truly is in both the books and the show). The wedding is meant to fortify the Bolton's hold of the North, something that Stark loyalist Wyman Manderly does not approve of. As such, a plan is set in motion to make the wedding go horribly wrong (so, basically, it's just like every other wedding in Westeros).

In the trailer, Littlefinger tells Sansa, "There is no justice in this world. Avenge them." Then, we see Sansa walking around in the crypts of Winterfell. The show always does its best to eliminate extra characters and combine storylines for the sake of storytelling ease. Is it possible that Sansa and Littlefinger will take the places of Jeyne Poole and Wyman Manderly?

The show has already changed Sansa's storyline from the books to make her more active in the never-ending power grabs and more manipulative. This theory would take that change one step further and put her right in the thick of things, amping up the dramatic stakes for her character.
