I know people say Feysand is Hades x Persephone, but NO. Wrong. They're Beauty and the Beast as well. Rhys is literally described as having a beast mode/version/side. People are scared of him. He's misunderstood, etc. And because these are retellings, some things are changed. Like for instance, Rhys teaches HER to read, the way Belle taught the Beast to read in the Disney version (I can't recall if they do that in the original fairytale).
I think Tamlin x Feyre were the BatB fairytale retelling, and Feysand were more the Disney BatB retelling.
Hades kidnaps Persephone in the original story. Rhys tells her he wants her to come to the Night Court as part of her deal. You know who else makes a deal to stay with them? Belle and the Beast.
And yes, Rhys takes her away from Tamlin, but that's literally the only similarity to Hades x Persephone they have. Feyre was never spring-like to be Persephone, but who is?
ELAIN.
Elain is actually going to be the Persephone retelling. She is SPRING and where is she? In the Night Court, aka The Underworld, and ope, who is the male she likes? Azriel. Hades kidnaps Persephone and makes a deal to keep her in the Underworld. I don't think Az is obviously going to "kidnap" Elain, he doesn't need to, but I do think some sort of deal will be made, finally ending any sort of tie of her to Lucien and breaking the mating bond (because let's be honest, everyone and their mate getting together is boring af and is honestly why I'm kinda eh about all the mate reveals in her books now but I digress). Also Az's personality fits Hades much more than Rhys did. Hades has been written as a quiet, reserved introvert who likes to stay in the "shadowy darkness of his realm". Does that sound like Rhys or Az? I mean. It's right there, really.
Now the other retelling was Snow White and The Seven Dwarves, and other than a total crack explanation that Nesta went through several men before finding her prince, aka Cassian, (they did say her mother wanted a prince for her and Cassian was referred to as the Prince of Bastards so....?) it's hard for me to really place them as Snow White, but there wasn't another retelling in the first three.
People say oh three brothers, three sisters, so boring. And everyone and their mate getting together is what? Not boring? Not easy? I would LOVE for someone to finally break the mating bond and say yeah no, I don't want you.
Possibly hot take: Nessian would have been 100000000x better if they didn't turn out to be mates. The reveal at first was like WHAT. And then like five seconds later, I was like, "ope, wait. I hate this."
