But one of the more unexpected and interesting developments in “Eastwatch“ was the raven Arya discovered in Littlefinger’s room.
I’ve been wondering for weeks what Littlefinger’s endgame is, and “Eastwatch” finally made that clear: Pitting the Stark sisters against one another so Littlefinger has more control over Sansa.
It’s important to remember that Sansa wrote this letter under duress, when Cersei (along with Pycelle, Littlefinger, and Varys) manipulated her into writing it.
Littlefinger is likely just trying to cause a rift between the two so Sansa turns to him for counsel.
