Who Gets Winterfell After This Week's Game of Thrones Episode?

In season five, Littlefinger and Cersei make a deal — in exchange for leading a Vale army to take the North for the Lannisters, Cersei will make Littlefinger the Warden of the North when Stannis Baratheon and the Boltons are defeated. However, now that Stannis and the Boltons are out of the picture, Cersei no longer has any power and their deal may no longer be valid. The finale preview shows Littlefinger and Sansa having a heated discussion, and it could very well be about who'll be in charge of Winterfell.
