One massively important detail could have huge consequences for Littlefinger

Extremely interesting.

Game of Thrones fans gather, and now my watch begins. It shall not end until my death. I shall take no wife, hold no lands, father no children. Reveal no spoilers without providing a warning. All men must die, but part of the intrigue in the world's best show is finding out how this happens. In the case of Littlefinger, we've always just assumed that the Machiavellian schemer will stick a round forever because when it comes to playing the game of thrones, nobody does it better. After all, he set the entire War of the Five Kings in motion when he conspired with Lysa Arryn to poison her husband, Jon. Remember him? Jon Arryn was the hand of Robert Baratheon and after his death in the very first episode, King Robert asked Ned Stark to be his most trusted adviser. Here's Jon in case you forget. Of course, Jon's death set in motion the chain of events which led every member of House Stark to the present moment, but the recent episode of Game of Thrones saw that rarest of things, Littlefinger getting caught up in the web of his own deceit. Cast your mind back to the end of the very first episode when Ned and Catelyn Stark were lying in bed together. Maester Luwin enters the room with a raven from from the Eyrie that's sent by Lysa Arryn. "She says Jon Arryn was murdered by the Lannisters, she says the King is in danger. Lysa's head would be on a spike right now if the wrong people had found that letter," remarks Catelyn. On the basis of this letter, Ned Stark and his family traveled to King's Landing as the game of thrones began. Ok, fast forward to the period when Sansa has now fled King's Landing and her abusive relationship with Joffrey. Thanks to Littlefinger's help, she has now taken refuge and shelter in The Eyrie, although she has to contend with the incredibly erratic, unstable and jealous Lysa Arryn. After Lysa saw her new husband (Littlefinger) kiss Sansa, she flew off into a fit of blind rage and threatened to push Sansa through the moon door. After grabbing her hair and edging Sansa closer to the abyss, Lysa threateningly screams "He is mine! My father, my husband and my sister. They all stood between us and now they're all dead! That's what happens to people when they stand between Peter and me. Look down! Look down Look down!" At this point, Petyr Baelish enters the room and Lysa screams at her new husband. She says:  "You want her (Sansa)! This empty headed child. She's just like her mother, she'll never love you. I lied for you! I  killed for you! Why did you bring her here here why!?!?!" Moments later, Littlefinger throws his new wife out the Moon Door. Well, fast forward to the most recent episode of Game of Thrones and dwell on one particular scene that took place in Winterfell. Do you remember when Sansa, Littlefinger, Yohn Royce and Maester Wolkan are discussing the issue of "the longest winter in the past 100 years?" Not knowing the answer, Maester Wolkan says that he'll check Maester Luwin's records because "he kept a copy of every raven scroll" that was sent to Winterfell. Now, in this precise moment, Littlefinger did a curious little glance in the direction of the Maester. If Luwin kept a record of every scroll - and Sansa clearly knows that Lysa is capable of murder in collusion with Littlefinger as per their chat at the Eyrie - it's almost certain that Littlefinger will be trying his very best to hide any deceitful tracks. What might this be? Well, how about a scroll that was sent from Lysa that implicated the Lannisters in Jon Arryn's death? Sansa knows that Lysa has killed and lied for Littlefinger, but when this news is combined with the damning scroll, Littlefinger could be in massive trouble. Will he get caught trying to destroy evidence? All this without mentioning the fact that Maisie Williams (Arya) was photographed with a very familiar dagger during a promotional shoot. Some speculate that there may be another scroll that links Littlefinger to the Valryian steel dagger that was used in the assassination attempt on Bran. It's worth noting that this dagger makes an appearance in the next episode. In case you need reminding, Littlefinger currently owns that dagger. Oh yeah, here's a shot of Sansa suspiciously looking through scrolls that also appears in the next episode. To quote Lord Baelish, "Chaos isn't a pit. Chaos is a ladder. Many who try to climb it fail and never get to try again. The fall breaks them. And some are given a chance to climb, but they refuse. They cling to the realm or the gods or love .Illusions. Only the ladder is real. The climb is all there is." There might not be too many steps for him left to take.
