Charles Dance completely sells the scene, which not only world builds, but also shows the power dynamics shift more and more in Tywin's favor, something which seemed to be lacking notice towards the end of ASOS outside of Jaime's one chapter where he and Tywin buck heads.
Additionally, this time I'm truly grateful for all the Cersei reaction shots we get as we truly get to see her realize that Joffrey is a footnote in history and will swiftly be forgotten and derided--and that she put so much energy into him for nothing considering how her father is prying Tommen away from her.
They undo Arya and Sandor's arrangement so quick, you hardly have any time to feel invested in Sally and her father before they're gone. I kinda feel that they moved the "departure" scene around from where it was intended to be, closer to the ending of the episode.
