Littlefinger’s plan in Game of Thrones season 7 was to turn Sansa and Arya against each other, and in the end it was he who was executed. So did Arya and Sansa know they were being manipulated by him from the start and just played along to make him show his cards? Or did they learn late?

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—.”
