Bran
Det här har egentligen ingenting att göra med Sansa eller Arya, men det är uppenbart att Bran i princip berättade för Sansa. Implikationen är att Sansa faktiskt inte hade lärt sig något och faktiskt trodde att Arias var den skyldiga och att hon skulle bli dödad. Men innan hon gjorde det frågade hon Bran och han berättade för henne att hon var en muppet. Detta påstås vara i en raderad scen.
It’s clear after Sansa turns the tables on Littlefinger that she has had some sort of conversation with Bran, but we don’t get to see it. When did it take place?
We actually did a scene that clearly got cut, a short scene with Sansa where she knocks on Bran’s door and says, “I need your help,” or something along those lines. So basically, as far as I know, the story was that it suddenly occurred to Sansa that she had a huge CCTV department at her discretion and it might be a good idea to check with him first before she guts her own sister. So she goes to Bran, and Bran tells her everything she needs to know, and she’s like, “Oh, s—.”
