Bittersweet

Oh! The intimacy of adopting each other’s vocabulary.

maybe alicent is traumatized and thats why she keeps thinking rhaenyra will kill her and her kids‘ kids

to think that all season rhaenyra has been looking at alicent so softly and many times, she has been bathed in light with the framing of the shots. now that light hasn't been surrounding alicent this episode and rhaenyra is giving her such cold looks. rhaenyra has been trying to give alicent assurances left and right and seeing how none of that softness has done anything to keep alicent at her side, she is withdrawing it. she refuses see alicent in a warm light anymore because of how betrayed she feels

Alicent probably thought that the most difficult thing about her conversation with Rhaenyra would be convincing her that Helaena had magically detected Aemond's location but instead Rhaenyra was like oh she's a dreamer! Fantastic, now go to Harrenhall and kill your son.
