Warning: Game of Thrones spoilers. Obviously.
Arya Stark has had a few stale seasons on Game of Thrones. Despite being a fan favorite, the badass, needle-wielding character found herself stuck in endless Braavosi Fight Club-esque training montages against the Waif.
Simply put: A girl had no plot.

And just when Arya's storyline began to thicken during Season 6's "Blood of my Blood," she went and carelessly got herself stabbed in the following episode, "The Broken Man."
But a GoT fan has provided a theory that gives a Arya's story a new, mind-boggling layer.
Reddit user catNamedStupidity claims Arya and the Waif are one-in-the same. The Waif, the Redditor suggests, is simply a figment of Arya's imagination (caused by the House of Black and White's magic) which is working to kill the humanity holding Arya back from fully becoming a Faceless Man.
The Redditor defends his/her theory saying it would explain why the Waif always knows what Arya is doing, where she is and when she is lying — she is essentially Arya's subconscious.
