Game of Throne Theroy on Arya-spoiler warning
If you have watched the previews for this season of GOT, you will have seen the science where Arya is running through the crypt. The theroy has been that she is being chase by someone or something. I have another theroy that she is running through the crypt because she is running to warn the people to get out. Because as we know on the Game of Thrones the place that is suppose to be the safest always ends up being the least safest. Arya has realize that they are in danger in the crypt.
