Game of Thrones Season 6 Discussion [SPOILERS WITHIN]

[Aegon]

I am reading a theory about Arya and the Waif right now.

The theory from a fan states that Arya and the Waif are the same person, a Fight Club scenario.

After all, it would explain why the Waif attacked Arya and no one would come to blind Arya's help.

Yeah, I read that. That theory implies Arya is now a stone cold Faceless Man, which I don't like. 

The theory I prefer is that it is actually the Waif who has failed, and Jaqen is sending her as part of Arya's final test. The Waif has clearly had a personal vendetta against Arya, something a true FM wouldn't have.

But in the end I doubt either of these are actually true, Arya will somehow kill the Waif and escape Braavos and sail to Westeros.
