Jaime and Prince Doran speak about the terms with Myrcella. He has no plans of letting her leave Dorne. He also says that what Jaime and Bronn did were unacceptable in terms of the infiltration plan. He threatens Jaime in a calm manner and tells him that if he wants to leave Dorne, he has to become a spy for him in Kings Landing. Jaime agrees.
.
Ramsay carries out the 20 man terrorist attack on Stannis' camp.
It's a decent action scene and sums up Ramsay's style of killing. Few good one liners in there as well. Rest of Stannis stuff is irrelevant conversation just to fill time before the Ramsay attack.
.
BIG BIG scene in Meereen as expected.
Dany spectates the Grand Opening of the pits with Hizdahr and Tyrion. Jorah fights in the pits and pretty much wins his fight. Tells Daenerys about his greyscale and says that he has nothing to live for apart from her. It seems like she might be convinced this time, but this is interrupted as the Sons of the Harpy infiltrate the pits and surround Dany and some others. Hizdahr is revealed as the leader of the Sons of the Harpy. This is before Drogon swoops in and tears everything up. Pretty much burns all the Harpies and civilians alike. Hizdahr and Jorah both die while Daario and Tyrion manage to evade the fire and keep Missandei out of danger. Dany meanwhile is trying to control Drogon and she gets really emotional and screechy over it. Pretty good stuff from Emilia Clarke tbh. Drogon swoops her up and flies off, episode ends with Tyrion staring at the remains of Drogon's attack.
