This episode don't have any mistake, along the series you will find that Alan Tylor's episodes are the best, and each -before the last- episode at all seasons contains a battle , you may think that the conversation between Tyrion and the whore was just a story but it contains a lot of wisdom and genius statements written by Gearge RR u will understand this at season 5 , I didn't love anything than this great show and I hope to see GOT 2019.
