(Spoilers Extended) 2 questions regarding lack of continuity in the show.

1. Dorne.

Now that the Martels and Sand Sneks are gone, who controls Dorne? Who governs them? If I recall correctly, Dorne has a pretty big and strong army. Who controls it now?

2. Last time we saw them, the Unsullied were at Casterly Rock, besieged (?) By Euron. Since lots of travelling had occurred in the show, surely something must have happened there. Or is Euron just waiting there? While the Unsullied have no food?
