^We have some clue reading next chapters.
I'll avoid spoilers.
There's something strange in Littlefinger himself and is actitude with Sansa. When young, he put himseft on the verge of death when fighting for Cat without any chance. Actually, Cat had to beg for his life to Brandon Stark.
Now, he's treating Sansa as a daughter, but in a queer way: he teaches her his own tricks, buids a WF of snow to please her, finds her a betrothal,...but, anyhow...
He is now Lord of the Riverlands. He plans to marry Sansa with the heir of the Vale, and let everyone know who Sansa really is when the wedding.
We have read all that. It is known.
Now, lets see my guesses:
His only real opposition is Yohn Royce; he needs to entice him anyway. Name one of his sons "Lord of the Twins" could be a point.
Freys don't suit him in the riverlands and, besides, they're damned.
The northern Frey's hostages would cheer Sansa as the Lady "Stark" for her own sake and as gratitude to their saviour. (Sansa, cousin to the Lord and married to the heir, would receive the salute of the Vale)
Everything matches.
Now, he only has to let Stannis and Bolton fight each other and the Lannisters lose allies.
Next moves after the wedding:
Getting Sansa pregnant (very important)
Getting rid of Robert, (Sansa Lady of the Vale)
Wipe any trace of Freys
Let the heir have a "grievous accident"
With this, he'd be up to rule both the Vale and the Riverlands. Sansa is daughter of a Tully and niece of the last Lord, and that gives him some legitimacy. He doesn't want to face the Lannisters as far as they have Edmure captive. That´s fine for him. A swap with Riverrun's Frey would be better (both dead, of course).
Next move, go for the North. "All for Sansa"
Littlefinger rules!
