Nah, breh. Rhaenyra is one of my favorite characters on the show, but she's objectively pretty fukking awful at courtly life and politics, primarily because she was both uninterested and largely excluded from them until her mid to late teenage years, when the show starts.
Set aside whether or not her and Laenor actually tried to have kid or not. Popping out three kids with Harwin. Allowing Laenor to name the most recent one after his dead lover. Also allowing Laenor to show absolutely NO concern for their general existence. All are completely garbage, JR Smith dribbling out the clock level decisions. shyt, even her idea to smooth things over with the arranged marriage doesn't even make sense. The solution to the queen knowing your kids are illegitimate is to marry one of said illegitimate sons to her legitimate daughter?
The plan was to spend an extra generation giving the Queen's family back something via marriage when they technically already have it by birthright?
C'mon, breh. That's not efficient political posturing whatsoever.
