The Alicent I know and love is back. We have Alicent proving once again that, at her core, her driving motivation has always been her children and that she would do everything to help them. She has accepted that she may not be able to save everyone in her family, but no one can accuse her of not trying. No one can say she didn't exhaust every possibility or use every ounce of influence she still possessed to protect them. She once again got herself into machination gear and had them cogwheels turning in this episode when:
a) she got Orwyle to secretly deliver moon tea under the guise of a remedy for period cramps,
b) urged Helaena to take it because she didn't fall for Rhaenyra's "you know I would have spared him, right?" delulu narrative as she very well shouldn't because she knows all too well the brutal logic of power and that Rhaenyra and her council would be forced to eliminate all rival claimants to the throne regardless of their age to secure her position,
c) initially outwitted Mysaria by drinking the moon tea herself, sacrificing her own health, reputation, and safety to save her daughter, despite how violently ill it had made her before,
d) traded away the seven-pointed star necklace which she had been wearing since forever and which was synonymous with her faith and her own longing for her mother, to ensure safe passage for herself and Helaena,
e) once again did the impossible arithmetic of motherhood and decided that saving Helaena and her unborn baby's lives at the expense of Jaehaera was better than losing Helaena, the baby, and Jaehaera altogether in "a true MOTHER counts the cost to her CHILDREN" tragic calculus fashion she's been forced to make all her life,
f) wasted zero time in manipulating Mysaria once caught and used her wiles and any remnants of influence she could grapple with to appeal to Mysaria's opportunism and self-interest and entice her to exchange silence with the opportunity to play both sides,
g) as soon as she got another chance, she made a run for it with Helaena.
All she's been doing all the time is her best with the options that she has. She has NOT given up, she is not merely a prisoner who laments her fate, but she believes herself still actively responsible for her children's fate and survival, and so she continues to act and sacrifice pieces of herself as a real mother would.
