Things are getting very complicated in Dorne.
Prince Doranmust contend with insubordination from his nieces, the Sand Snakes, who are hell-bent on exacting revenge on the Lannisters, whom they hold responsible for the death of their father Oberyn. He must also deal with the political fallout after capturing Jaime, who came to Dorne to rescue his daughter/niece Myrcella, whom the Sand Snakes were plotting to harm.
Both Jaime and the Sand Snakes are in Doran’s custody, and their actions have big implications for Dorne’s future, as what Doran decides to do could potentially prevent or spark war.
