Season 6 General Speculation v8

No, haha a plan would be not sending his only son to his death, and at least accompanying one sandsnake with him to KL. Or at least a guard like Areo Hotah. Siding with Dany in this situation would be after Trystanes death, and not so much a plan but a convenience.

Kevan's in charge in KL and Myrcella was alive when Trystane left for KL. So it wasn't conceivably sending him off to his death at that time. He's safe in KL until Cersei comes back into her full power, which she probably won't at any point in s6. Also it's possible that he's still smuggled out of KL before that happens. Potentially by Varys.

Keeping the peace is his goal in the show.

Well, I never said otherwise.  Anyhow it's a more admirable goal in a way than supporting fAegon's doomed bullshit. He'll provide troops for Dany in s7, I imagine.

And if your Jorah-Golden Company theory is right then they could begin to invade northwards before Dany even lands in Westeros.

As horribly written and ridiculous as Dorne was in the show, they obviously included it to show the reaction after Oberyn's death. I mean if they skipped another season it would have thrown off their plans for the KL storyline. Look I dunno wtf happened in the writing room, all I'm saying is that Doran will side with Dany and she needs allies in Westeros so he would be one of them for when she lands.

Dorne didn't have anywhere near enough screentime for it to have been traded-off constructively in s5 for either the Iron Islands or the Riverlands. So really it wasn't really an either-or proposition. The Iron Islands were delayed so that Theon would be our "in" to returning there in s6 which makes plenty of sense for adaptational purposes. And with the Dorne decision made and the focus in the North, the Jaime and Brienne reunion-delaying choice worked to consolidate screentime in those two locations insofar as it was possible.

But there was no way of just not returning to Dorne at all in s6 because of the reception towards the s5 arc. It's too tied-in to the goings-on in KL and will be central to the Cersei-Kevan-Jaime dynamic in s6. So some follow-up with Doran and Ellaria is necessary as well. Though it's likely to have very little screentime again of course, as it did in s5. s7 will be when its focus will increase, I think.

I disagree. Dorne got enough screentime to

1. Visit the iron islands, kill balon, hold a kingsmoot and reveal eurons plans to invade the reach hence setting up next season when sam gets there.

2. Jaime travels to riverrun, assesses the situation, up to the point where he receives cersei's letter.

They can't introduce whole new storylines without a main character, the Iron Islands with only Asha as an introductory vessel would not have worked for unsullied. There was honestly nothing wrong with the way they introduced Dorne, it makes sense in terms of adaptation, the real issues were in the execution.
