Just when you think Littlefinger couldn't possibly have anything else up his sleeve, he once again proves us wrong. But is it possible that Littlefinger could kill Arya on Game of Thrones? He's definitely up to no good. Ever since Arya walked back into Winterfell, Littlefinger has kept a close eye on her. Of course, that's undoubtedly due to her amazing sword fighting skills, which she showed off last week. But it seems he may be interested in her for other reasons, which could end up resulting in her death.
During Sunday night's episode "Eastwatch," Arya spotted Littlefinger receiving a scroll from someone, stating that Lady Stark thanks them for their service. He proceeds to take the scroll and put it somewhere in his room. But, naturally, Arya sneaks into the room to find it once he leaves. She reads the note, which appears to be from Sansa regarding someone trying to steal Joffrey's throne. We, as viewers, are unable to see the entire message, so it's unclear what this was exactly about. (Could this note make it seem like Sansa played a part in her father's death?) But whatever it says seemed to have completely shocked Arya. So much so that she didn't even notice that Littlefinger was watching her leave his room. I'm thinking he planted that scroll there to cause a rift between the two Stark sisters.
Whether Arya is ready to believe it or not, Sansa holds a lot of power at Winterfell these days. So if Arya were to threaten or even make any accusations against her in the coming days, there could be dire consequences. Littlefinger may have just planted a seed of doubt, but it could create a ripple effect that ruins this highly anticipated Stark reunion. Or maybe the note isn't fake at all. Perhaps this was a note Sansa sent all the way back in Season 1 when Cersei urged her to write a note to her mother and brother (Robb), telling them to side with the Lannisters after Ned Stark was arrested. I bet seeing a note like that would definitely be enough to make Ayra's blood boil.
Arya has already called Sansa out for wanting more power at Winterfell (she reprimanded her for not sticking up for Jon when the northern houses talked badly about him), so it wouldn't take much to create even more discord among these two characters. And Littlefinger is a professional manipulatory — particularly because no one ever catches him doing it.
I can't say for sure if death is what Littlefinger has in store for Ayra. (Though staring at her through the darkness isn't exactly a good sign.) But either way, he's up to something and given his track record it's bound to lead to only more trouble for the poor Stark family.
