“Funny enough, we did actually shoot a scene that didn’t make it into that episode where Sansa knocks on Bran’s door, and I don’t know whether they actually want to change the story, but as I understand it, Sansa came to Bran and goes, ‘Can you just look some of this up before I kill my sister?’ That kind of sentiment. Sansa just checking that fact,” said the actor.
