The Stark sisters are being played. Perhaps too easily, but this is the first time Arya Stark (Maisie Williams) and Sansa Stark (Sophie Turner) have been together in a long while. In the fifth episode of season seven, Littlefinger (Aidan Gillen) played the Stark women like fiddles.
"Arya is very used to being more clever, more stealthy and smarter than any of the people she's up against. She hasn't dealt with Littlefinger for a while, so she gets roped into spying on somebody who's actually leading her by the nose to something he wants her to have," series co-creator D.B. Weiss said in HBO's Game of Thrones episodic breakdown segment.
That thing is a letter Sansa wrote to Robb Stark (Richard Madden) forced by Cersei (Lena Headey) all the way back in the day (season one). Seems Winterfell has a really thorough records room.
"[Littlefinger's] looking for a way to prevent the sister bond from developing further because the tighter that bond is the more definitively he's caught outside of it. On the Sansa end of the relationship, she's seen the opening and now all he needs to do is give Arya pause to display real rage towards Sansa," Benioff. "He knows full well that with what's going on in Sansa's head with regards to Arya and how dangerous she is, when Arya starts to act dangerous and act angry, he knows where Sansa's going to turn."
