Kinda tempted to writ a what-if fic where in Silver Flames, when Nesta is given the "choice" to either get locked up in the HoW or being send to the human lands with the expectation to die there, she actually chooses the human lands, saying death would be better than surrounded by obnoxious hypocritical narcisists.
Feyre and Cassian would right away try to backtrack and just want to forced her to the HoW, only for Rhysand to be, "done" and just winnow her to the border and leave.
Back at the NC Feyre and Cassian would be pissed but Rhys just tells them he'll have eyes (not Azriel(he doesn't and hopes she'll just die and plans to pretend the pragnancy made him forget, even while also lying to Feyre about that)) on Nesta, along with some more manipulation and gaslighting till they just give in.
Nesta meanwhile tries to avoid being seen, but soon get's discovered and has to run from a mob, only to get saved by Lucien and Jurian.
They take her back to their manor where she's just in time to see Vassa transform from bird to woman.
She explains what happened and the BoE is disgusted with Feysand and their groupies and offer Nesta to stay with them and she accepts.
Slowly she gets better as she's treated by respect by the BoE and becomes friends with every member in some way (meeting sassy Lucien, mocking spoiled human lordling sons and daughters they grew up surrounded by with Vassa and talking about SMUT books, training with Jurian on her OWN CHOICE after watching him a few times and being offered to join, and all of them just being sarcastic and teasing each other.
They'd also discuss and ask her opinion on political matters( since, like many say, she was right away more suited and courtier than warrior)
When The IC finds out, first Cassian tries to get her back, only to be denied by Nesta and when he doesn't listen to her, get's send away by BoE.
He keeps coming around but keeps getting send away and Azriel starts spying and constantly reports moments where Nesta's happy and Cassian feels jealous of Lucien and Jurian, Feyre of Vassa for being sister-like with Nesta, and Elain of Vassa and also Nesta for being close to her mate.
Maybe have Eris coming over more often too and flirt with Nesta who flirts back, making Cassian worse.
At some point, Cassian get's told by Lucien he's a worthless matee who doesn't care about Nesta and will always easily put the IC over her, and Nesta confirms that while she likes (or liked?) him, he's not what she needs until he actually changes
She also, since she doesn't need to rely on the NC for protection, tears into Feyre for her I-always-did-everything-while-my-sisters-did-nothing attitude, mentioning all kinds of things she did that Feyre ignored and how she's become a selfish obnoxious hypocrite that flaunts money and laughs at those less fortunate.
Also at Elain for always sitting on her ass and being useless and trying to act like the victim after always having Nesta take care of her and protect her, yet turning her back on her as soon as she needed Elain to take care of her for once. Maybe also tear into her for being a bitch to Lucien and saying he deserves better than her.
In the end ereryone does get better but I don't know how yet.
