HotD ep. 1.09 spoilers: I like the last paragraph of this piece at Collider.
"Rhaenys chooses to show the newly crowned Hightower-Targaryens mercy, but not before pointedly looking Alicent in her eyes. With Rhaenys now towering high above the royal family, the power dynamics present earlier in the episode switch within an instant. While her choice to show mercy is largely contested, Rhaenys' actions at the end of the episode served to show Alicent what a woman's true power can actually look like. It is not a crown, nor is it boasting the feats of their husbands or sons, but it lays in the ability to yield the reins of their own fates."
