It was one hell of an episode of Game of Thrones this week and one no doubt you have many questions over, like just what exactly did that note say that Arya found in Littlefinger's room? And why did he want her find it?

Well here's a screen grab of it...

This was the note that Cersei made Sansa write all the way back in season one when she was still a naive love-struck young girl trying to get her dream of becoming a queen. Extremely irritating, in short.

Watch the scene below:

Here is also the moment Catelyn and Robb received said note:

In this week's episode, we saw Littlefinger orchestrate it so that Arya would find the note and made it seem like Sansa had instructed him to get rid of it, but why? As usual we find ourselves asking, WHAT'S LITTLEFINGER'S GAME??

Here’s what writer and showrunner D.B. Weiss had to say about it in the post-episode making-of featurette:

"[Littlefinger is] looking for a way to prevent this sister bond from developing further because the tighter that bond is, the more definitively he is caught on the outside of it. On the Sansa end of the relationship, he’s seen the opening, and now all he needs to do is give Arya cause to display real rage toward Sansa… 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."

There is already a visible wedge between the Stark sisters as Arya questioned why Sansa doesn't just behead the men slagging off Jon, while also taunting her with the idea that Jon may not come back and she could end up ruling the North. Both sisters seemed to have made the mistake of assuming they are the same people they once were and have picked up where they left off with their hostile dynamic towards each other. Can't they just sit down, have a glass of wine and I don't know, catch up?

Our hope is that somehow Arya and Sansa won't play into Littlefinger's hands and will ultimately come together to outsmart him, but we learned a long time ago that Game of Thrones isn't in the habit of giving us what we want.
