RIP Areo Hotah. RIP Dorne plot. Tying up loose ends, the plot was still partly following the books last season so it was spread all over the fucking place. Dorne is one setting the show-runners apparently felt they could lose, and given how badly they fucked it up and how poorly it was received I tend to agree. I doubt we will see much more of Dorne itself, one or more of the sandsnakes are just going to be inserted in various other storylines. One going to King's Landing, the other probably to seek Danny (replacing Quentin storyline?), stuff like that. They're not going to make things harder for themselves, and why should they? The plot can now be used in service of the medium, as opposed to every other season, where the plot of the books had to be addapted to an episodic television format. The massive divergences started appearing soon after the Red Wedding, but now they really have nothing shackling them.
