if it wasn't clear from the post, i'm not a fan of arya. i read a comment somewhere here not so long ago that compared her to bran. bran is not bran any longer, the three-eyed raven thing has gotten rid of a lot of his character and self identity. he's basically his ability, there is no bran anymore. what arya went through is similar, except.... she's still arya. she's still stubborn, vengeful, and a know it all who in reality knows very little. she hasn't really learned anything that would help her grow as a person. she's learned to kill. that's not growth. she's still a silly, prideful kid.

on the other hand, sansa has lived through a lot. she's learned a lot and changed so much. she's tough because she was forced to be tough and she's alive because she was forced to be smart. she let these experiences open her eyes to the game in a way that arya hasn't. sansa and little finger are so interesting to me because they're both low key. you won't see them doing much, but they're thinking.
