I may be a little off with the nettles ( genuinely because I forgot she existed because I forgot this book existed) but… i think the answer to it is very simple in a way people don’t like to admit: they gave her storylines to two characters who have been introduced and genuinely are off screen in the book until the very end expect for one instance for baela and nothing for rhaena.
I don’t think baela and rhaena are being seen as interchangeable, I think they realized a while ago that these two important late game characters have sparse to do in the actual war they are covering and decided to splice nettles into two halves for them so they have something to do.
nettles is a character with a great story, no doubt and the addition of a young poc in a series that literally has none to the point that they are often race swapped is nice and i say this as a poc. BUT.
not only does nettles storyline possibly go into something that is never going to finish and wasn’t in the showverse but above all, the use she has for the questioning of targ + dragon relations is done in the show without her.
“she proves you don’t have to look like a targ to ride a dragon” rhaenyras sons do that.
“she proves you don’t have to have targ blood to be a dragon rider” addam lowkey does this.
I absolutely think she’s an interesting character and believe her character as a whole does add something but I’m not at all surprised she got cut. rhaena having her storyline with daemon makes sense especially since they were already going into the dad-daughter stuff with him last season. baela having her gullet stuff and sadness over Jace makes sense for the same reason. atleast to me.
No, I agree with all of this. I think all of your thoughts here are well reasoned and they are undoubtedly why they cut Nettles. I don't think anyone at HBO was condensing black characters into one with the intention of being racist
But I do think that optics wise it's still quite iffy to merge her away with Baela and Rhaena. It does make you think that someone behind the scenes had to think, "well, they're all black, so we can do that without being accused of whitewashing" the way they would have been if Baela and Rhaena were white here
