Game Of Thrones Season 6: 10 Ups And 2 Downs From 'Oathbreaker'
4. Arya Gets Her Sight

Arya's storyline was starting to drag a bit, after two weeks that offered little more than a 45 second check-in to watch her getting smacked around by the Waif. This week was something different though.
This week was a 3 minute check-in to watch her getting smacked around by the Waif.
But seriously, this was a marked improvement for Arya, as it actually felt like her story was progressing a bit. She actually manages to defend herself against the onslaught of attacks, and the questioning feels like it has more importance to her character - she's convinced everyone, maybe even herself, that she's no one, but it also suggests that Arya Stark is still in there somewhere.
Her getting her sight back was welcome, as there wasn't much further they could take the blind angle, and after more interesting episode for her, things are looking up.
