A deft little scene between Ser Petyr Baelish and Brandon Stark/The Three-Eyed Raven came to a curious conclusion you can be forgiven for not understanding the impact of this week, involving a reference that links back to season 3.
Littlefinger was up to his usual ‘you can count on me I’m a straight shooter’ schtick in Winterfell, sympathising with Bran: “I imagine you’ve seen things most men wouldn’t believe. To go through all of that and make your way home again only to find such chaos in the world, I can hardly imagine – ”
He was cut short by Bran, who said blankly: “Chaos is a ladder.”
Bran was quoting Baelish himself, who had the following exchange with Varys in season 3 episode 6, ‘The Climb’
So why did Bran choose to repeat this assertion to repeat?
He was basically letting Littlefinger know he is wise to his games. Bran has seen literally everything in the Seven Kingdoms, including Littlefinger describing his philosophy of manipulation at a time when he was allied to the evil Joffrey. Bran presumably knows Littlefinger played a role in his father Ned’s death, and it might have just placed him on Arya’s kill list.
Bealish has had little luck deceiving the Starks so far this season, also having run-ins with Jon and Sansa over his silver tongue.
