As Areo Hotah, we once again watch the goings on at the court of Doran Martell in Dorne. Timeline-wise we must be joining up with the end of A Feast for Crows, if not now then soon.
Ser Balon Swann has finally arrived with GREGOR's head. Except it probably isn't, because Qyburn has the real GREGOR, I think. But it will do for now. Balon Swann looks a bit suspicious and uncomfortably. Myrcella is not around; she's hanging out in the Water Gardens, playing in the water with all the other naked children, presumably. He's going to be a bit annoyed when he finds out about her missing ear.
However, Doran and Arianne have cooked up some story about how Ser Gerold Dayne aka Darkstar was the one who attacked her. I suppose this somehow absolves the Martells of blame. Somehow they have got Myrcella to believe this, too. Meanwhile they have got wind that Cersei, having invited Myrcella and her betrothed Trystane to King's Landing, was planning to have them ambushed on the road so that Trystane could be killed. So they're going to subvert all that by sending Balon Swann off to avenge Myrcella and send Nymeria (Oberon Martell's daughter, not the wolf or the god) to King's Landing as a spy, and Tyene (her sister) to the sept at King's landing to spy on the new High Septon and his army.
Presumably they will get there and find that Cersei is no longer in charge anyway, so that will be fun! I quite like these Martells. They're pretty clever and not so nasty as some of the other factions. Apparently the point of the naked children in the swimming pool is you can't tell the high-born from the commoners, which teaches a noble lesson about equality. And it seems like they're a bit nicer to their women, too. But it's not all political correctness gone mad: they're expecting Dany to turn up with an army to wipe out the Lannisters any day now: ships may be on their way.
But we know it's not Dany, it's probably Price Aegon. Maybe that's just as good for their purposes, though.
