Which Does Not Currently Exist Because The Book Dynamic Is Relatively Simple To Explain - Tumblr Posts
It's interesting hearing people talk about the polycule in the books vs show, and the possibility that the show will go "full polyamory" or whatever. There's this implication that the book polycule would have been more accurate if Min had also been dating Elayne and Aviendha, so all four characters would have been romantically entwined together.
Obviously it's a fantasy series and the writers can do whatever they want, but irl most polyamorous people date individually in dyads, rather than 3+ person relationships. It's much more realistic that not all of Rand's partners are dating each other.
Triads, quads, and other group relationships are uncommon in polyamory because they're notably more difficult than dyadic relationships. Lots of newbies experiment with them because of the stereotype that it's how polyamory works.
Anyway, this is all to say that I think the relationships in the show will work best if Rand is dating all three women, Elayne and Aviendha date each other, and Min only dates Rand. Developing romantic relationships between Min & Aviendha and Min & Elayne would take more time than the show has, and it's not necessary for the polycule to work.
