re: Crackpot ASOIAF Theories SPOILERS

I bet I know what's going to happen to the Freys. First the Boltons will fall (aside from Ramsay who has taken over the Wall, but his time will come later in the book) due to Stannis and some internal backstabbing. Littlefinger, knowing that the Kingdoms have never been in as much chaos as they are now, sends word to Cersei that he's marching North with the army of the Vale to secure the North.

After marrying Sansa off to whatever his name is, they'll march North to the Twins, and once they're inside, they'll proceed to massacre the Twins and kill all the Freys. Littlefinger will then announce Sansa's presence to the world, as well as the Vale's and the Riverlands' loyalty to "The Queen in the North". She and Littlefinger will become instantly popular needless to say for basically wiping out the most despicable and despised family in all the Seven Kingdoms, and also putting the final nail in place for the destruction of the Lannisters,
