I think Sansa is clever, but I think that what is important about Sansa more than that she is clever or that she will “come out on top” or end up powerful (she may or may not come out on top or end up in power!) is that Sansa Stark is kind, and she remains kind despite all the things that have happened to her. I think when people defend Sansa from h8rs they often try to point out things about her that are valuable to her but ultimately not really accomplishments? She learns to be clever and manipulative because she has to. She is kind out of choice, and persistently kind in the face of overwhelming cruelty, and that is why I love Sansa.
