The King of the Narrow Sea offered a lot of progression, and we see Rhaenyra learn how to wield her own power. She discovers herself as she sheds her innocence and actively takes a step towards the dark side like everybody else. Its a slow metamorphosis but she’s getting there. Too bad we will only see Milly Alcock in the role for a couple more episodes.
Despite the lack of action, it was still a good episode. After all, you can’t have a war with each installment. Still, I would have Daemon or Rhaenyra sit on the Iron Throne any day over Viserys. And any episode with dragons is awesome.
