Garlan, last we knew, was on his way back to the Reach to fight Euron at the Shields. I'm not talking about Garlan, I'm talking about Willas, eldest son and heir to Highgarden. I'm talking about the fact that Randyll Tarly would never tolerate an attack by the Greyjoys on the Reach. I'm talking about the fact that the Krakens never go inland or actually hold territories, and when Asha did it in the North it was seen as a fool's errand.
And then, to go back to Dorne - Myrcella isn't even dead in the books. If she dies (which would line up with the prophecy), it seems likely it won't be in Dornish hands. The Darkstar tried to kill her, Areo Hotah saved her, Doran's people nursed her back to health, and Doran is in the process of sending her back North with Jaime and one of the Sand Snakes, Nym. Not to mention Doran dealt with the Sand Snakes decisively and has Ellaria handcuffed in terms of what she can get away. No, in the books, it seems like Myrcella is likely to die because of something Cersei does, which is, narratively, a more sensible direction for her death, and probably as a pretext for war with Dorne.
Garlan - Jesus. Who gives a shit about Garlan?
