And of course, she was the administerer of the cruel justice of the episode’s title, as she had her revenge on Ellaria Sand. We figured nothing pleasant would come out of Euron Greyjoy’s pledge, made in the season premiere, to bring Cersei a priceless gift. He is a savage marauder, after all, and she a ruthless striver — both claimed power through shocking acts of violence. What would be twisted and depraved enough to serve as a fitting engagement present for the story’s most psychopathic pairing since Ramsay and Myranda hunted girls together?

Turns out Euron’s kidnapping last week of Ellaria and her daughter Tyene was the demented pirate equivalent of a trip to Tiffany’s. He presented his prize at the Red Keep and then Cersei subjected Ellaria to the same horror that she herself had suffered with the loss of Myrcella, fatally poisoning Tyene with a kiss.

It was an eye-for-an-eye with a twist: Ellaria will now be made to spend the rest of her days rotting in a cell, alongside her daughter, who presumably will do so in more literal fashion. The punishment called back to Cersei’s own dark terror, expressed last season after Myrcella’s murder, about imagining dead loved ones decomposing in the grave. You will “watch her beautiful face collapse to bone,” Cersei told Ellaria.

Which is to say that like many punishments, it said more about the inflicter than the victim. It was a sign that even though Cersei 1) achieved ultimate power in spite of her enemies and oppressors, and 2) effectively solidified it through some savvy moves, she is still haunted by loss and fear and focused on settling old scores. At the same time Jaime, her closest companion, seems ever more uncertain about the future, which could be a problem.
