True Mates
I think **True Mates** are a combination of **Fated Mates** & **chosen mates.**
SJM specifically cited Feysand & Nessian for her examples of "true mates." Both of these couples are fated mates but more importantly, they chose each other as well. The love there is genuine. It's not merely an acceptance of their fate & putting up with it but e.bracing it with every fiber of their beings. Not just tolerating it, but needing each other and loving each other. Soulmates as well as fated mates.
Elain has her work cut out for her on her journey to accepting anything! But I believe that something will bring her and Lucien into forced proximity where things will be revealed and she'll get to truly know him, even if it's not intentional on her part (at first anyway).
Thr concept of mating bonds and questioning them will be explored in this scenario. Really nothing new since her sisters reacted badly at first too! But she has a lot of trauma with being turned & believes him to be a part of that so it's going to take a bit. She's going to rebel against the concept, etc.
BUT their union will ultimately be one of fated AND choice, just like what her sisters have. It may take her a bit longer to get there, especially compared to how long Rhys & Cassian had to wait once they recognized their mates, but I think Elain's journey will be all about choice, and what it means to choose your mate.
So it will be a journey of choice and acceptance, not settling for her fate, but rather, learning to embrace it.
She will give Lucien a chance eventually, not **BECAUSE** of the mating bond but **IN SPITE OF IT.** Thus blending fated mates and chosen mates into true mates. Just like her sisters have.
