That was a great final episode
Spoilers below only from the final episode, not the books :P
Love how Arya's character (my fav one) has developed into this stone-hearted girl because she has just seen so much loss and darkness in her life. But there is still a sliver of the innocent little girl in her which was evident when she was chatting with Brienne about how she learnt to fight. That whole segment was excellent.
The action was excellent in this one. Especially Brienne vs Hound. Loved how it turned from an honorable sword fight to kicks-in-crotches and biting-ears skirmish :P
