ASOIAF / Game of Thrones (SPOILERS INSIDE)

[Sidelle]

I've been doing some thinking about Arya. In "A Dance With Dragons" we learn she will be entering an apprenticeship with Izembaro to become a Faceless Man.

Anyone have a theory about who she will eventually be killing? I believe it will be someone of importance to the story. Might want to put on your tinfoil hats now...

I think she will eventually be the one who will kill Littlefinger so she can save Sansa. It's just an idea. Might be crazy, but I think a little crazy is ok in this thread. To me it seems obvious that her path will become important somehow most likely by killing someone of importance. I just can't guess who or how with certainty. I just believe she will do anything to bring her family (pack) back together again. Ned did tell her that the lone wolf will die, but the pack will survive.

No matter how petty and immature Sansa and Arya were at one point, they have both grown up fast because of everything that happened with their family. They will need each other.
