I kind of hate how HOTD doesn’t go into how dismissed Rhaenys was in terms of Queenship.
She was never once considered for the throne, even at the Great Council she was immediately dismissed and the claim that was debated was her son, Laenor, vs her cousin Viserys. She was never once considered by either her grandfather or by The Great Council as even having a claim.
We never get this brought up once in HOTD, despite it being mentioned repeatedly in Fire and Blood that she was dismissed as an heir. Even her father said to her that he wanted a “grandson” likely because he would have placed that son as heir before his daughter.
It’s so frustrating that the show implies the Great Council was a choice between her and Viserys when it never was.
