I've touched on this in the past, but heres proof side by side.
So, everyone when talking about the bonus chapters, in terms of gifts, its that Azriel regifted the necklace (originally intended for Elain) to Gwyn.
But theres a parallel, with Elain and gifts, in the Feysand bonus chapter.
In Azriels Bonus Chapter, Elain returned the necklace he gave her. And yes, he went on to regift it to Gwyn, blah blah. Again, the regifting of the necklace is not the point. The fact that Elain returned it is.
Because why would she do that, if what she felt for him went beyond a simple crush? Why would she return it, if she still loved him so much, even though he said their almost kiss was a mistake?
Why would she go through the trouble return the necklace Azriel gave her, yet still keep every gift Lucien had given her, right back to, and including the jacket he used to cover her up, after she fell out of the Cauldron?
Now, yes, the jacket is an assumption. But two Solstices have gone by, two confirmed gifts from Lucien, and its confirmed that she keeps the gifts from Lucien, even if she ignores them.
If she loved Azriel, and hated Lucien, would it not be the other way around? Keep the necklace, despite the pain, and return/refuse the gloves and pearls?
SJM intentionally included this very subtle parallel between the two bonus chapters. Its not for nothing. Nothing is ever coincidental with these things in her books.
So why? Why did Elain return one, and keep the others?
