For the first five seasons of Game of Thrones, it seemed like Sansa Stark was really one of the most unfortunate characters on the show. But she managed to survive and now in the latest season, she's slowly turning into a badass. Here's a theory:

After chilling with Littlefinger and Cersei in court, her training is complete. This Reddit user's fan theory says she's going to get her moment and it starts with the letter she sent to Littlefinger.

It's basically a ploy to get Ramsay to intercept the letter and send a bunch of his troops to take care of the knights of the Vale.

Either way, it looks like Sansa can very well take care of herself already.
