It wasn’t a fake Sansa, it was a fake Arya.

You know what? I do believe you are right. It has been a few years since I read the books. I guess watching the show since then muddied the waters. As soon as I read the first sentence you wrote, I realized my mistake.

Thank you for correcting me. Now I will have to rethink my predictions for the show.

I agree the books are great just as they are. However, I also like the show just as it is. I enjoy trying to find the discrepancies between the two. That’s just my opinion.
