Don't feel like you need to drop it, I like talking like this, and with no new comics, what else we gonna talk about?
And I guess what I'd say to that, is yeah, I do think they are kinda soulmates, and that may make Zelma (or whoever else) feel like kind of a third wheel, but, first, the same maybe could have happened with a guy. Like, I would definitely say a lot of same sex platonic friendships you see both in real life and in fiction have that sort of soulmate aspect, but there is no expectation there that it become romantic, and it's just kind of dealt with in terms of the romantic partner(s) of the Platonic Life Partners. And secondly, as for the drama that may cause.... While I know we may think we want things to go super smoothly for our fave characters, a bit of drama helps keep the story interesting. It may complicate things for Loki, but will make the story more interesting for us to read. I don't want it to become mired in drama, but a bit of jealousy or weirdness about having to share Loki's attention could lead to some interesting story beats.
I mean, same deal with Thor in, er, Thor. On the one hand, as a fan who wants the brothers to get along, it was disappointing to see Thor chuck Mjolnir at Loki's face, when he was doing nothing wrong, (and Bill and Sif, and whoever else he may throw it at next, maybe his mom at this rate) but I also recognize that if things always went smoothly between them, it wouldn't be as interesting. But I do still have hope that they can work things out, and think they can, once Thor gets over what he's going through.
Very tangentially related, but that is also kind of why I keep hoping for this 'roles' thing to play out the way it seems like it might. I actually don't think that the whole 'roles' hierarchy thing is a GOOD system for them as characters, even if Loki does land a good role this time around. I think it's suffocating, it downplays or even negates free will and character agency, it might lead to characters acting in ways they don't like, especially Tyr this time around, but that goes for all of them, just acting in a way that doesn't seem to fit their inner selves. Like how Loki seemed to feel he was forced to fill a certain role in the leadup to WotR. Just, the characters are not free to be their authentic selves because they are shackled to this system that they are unable to escape from. BUT, I think that conflict and the restrictions it imposes is exactly why it could be interesting. Whether they become aware of this system or not, if they recognize that they are being pulled down a path they would not have actually chosen for themselves, that creates some interesting inner conflict. and if they do become aware of the system, then you could get into existential questions, meta stuff, and a debate over whether it would be better if the system stay in place for the good of the universe, despite the cost it takes from the characters locked to the system, or if it would be better for the characters to try and dismantle it so they can be free. Or is the hierarchy and the roles it supports more important than their personal happiness? when you think about it, it really makes sense why Loki may have landed the central role this time, because these exact questions have been plaguing him for the past 10 years, since his entire motivation for all of that always boiled down to trying to change his role in one way or another, but he couldn't, at least not fully. He could change his inner self, but the role kept trying to force him down a different path in terms of his actions. It just was never quite explained why it never worked until now, just kind of hinted at, and now it looks like we (and he) may be getting answers.
