From what I've been led to believe, this is where Arya's story starts to get very interesting. She arrives in Braavos full of hope in search of the Changy Face Man from season 1 whose name I appear to have temporarily misplaced. Now, watching this next scene, I was struggling to place something else I'd seen fairly recently that involved a girl going up to a temple for training and sitting on the doorstep until they agreed to take her in. I couldn't for the life of me remember what what it was until Emma dragged it out from the back of her subconscious. If you haven't yet watched the recent reboot of ThunderCats then I highly recommend you do so. In a flashback during episode 12 you will see a young Cheetara trying to gain entry to the temple of the Clerics. I'm fairly sure one of them must have influenced the other, whether it was the books influencing the cartoon, or the cartoon influencing the show. The similarities are uncanny.
