10. Arya's Training
Picking up after the Season 5 finale, which left her blind as punishment for taking a face and killing Meryn Trant, we meet Arya this year as she's out begging on the streets of Braavos.
She's even more beaten and broken down than before, and that's without the Waif getting involved. When she appears things only get worse for the youngest Stark girl, as they begin her 'training', which at the moment is basically just the Waif beating a blind girl with a stick.
This works, though, because the audience cares about Arya, and we now at least know her storyline will be headed somewhere, even if it won't always be a pleasure to watch.
Maisie Williams has teased that we'll see her really suffering this season, but at the same time we're going to see her continue on the path to becoming a Faceless Man, and that training and battle between no one and Arya is going to be great to see, and this was the first taste, as well as re-establishing the conflict between her and the Waif.
