holy shit those headcanons are fucking wonderful and I'm glad I didn't go to sleep yet. UH please tell me there some happy endings here because i want there to be happy ends. i want to know that everything works out in the end and they become a wonderful, happy OT4. Like how does the arrangement work, what lines are drawn, does gladio talk about how he really did want them but just couldn't get the words out GOD I WANT TO WRITE FIC ON ALL OF THIS BUT I WANT TO SEE EVERYTHING YOU HAVE i'm ruined
Let’s be ruined together!
So. I choose to believe it all ends happily as a wonderful little OT4 pack unit, though it probably takes a little (lot) or time to get there and work out all the little kinks and bumps and individual issues each party brings. No easy happily ever after, but a good one nonetheless.
I think things probably go through a few incarnations, where at first it’s sort of a V relationship, with Gladio as the point and Prompto on one side and Ignis and Noctis on the other. Then a…um. Some other shape, as a line appears between Prompto and Noctis (It’s not as easy a change as one would think. It is one thing for Ignis and Noctis to share a lover in Gladio, something different for just Noctis to take up with someone. And there’s some question over whether this means Gladio and Prompto are dating Noct together or…separately? And, for that matter, is Gladio dating Noct and Ignis as a unit? And once they decide that sorta yes but also no there’s some alpha conflict and…look. It takes work.) Prompto and Ignis together takes more time because…well because it does. But when it does they sort of settle into it like ‘hey, this makes sense right? We’d be good together too, wouldn’t we?) Jealousy happens, is worked through, happens more, they fret, decide they’re only human, and learn to deal.
There’s a lot of line drawing and redrawing and boundaries and things to consider and dos and don’ts.
Gladio and Ignis probably have the hardest time, because alpha sensibilities are a thing. They snipe and growl and occasionally push too hard, or not hard enough, and argue about space and things and it’s dumb territorial bullshit that Gladio kind of loves and Prompto and Noctis think is stupid (why can’t alphas be in packs together? Some omegas have big Omega Only packs, even. Alphas are dumb.) Gladio has some envy issues. Ignis has some ‘sometimes his body says ‘omega’ and ‘mine’ and he wants to bite Gladio’ issues. Or ‘sharing the omegas’ issues. Or ‘Gladio is in heat and doesn’t care that they might be intimate at other times, if Ignis comes near him he will stab him’ issues. And ‘Gladio and Ignis are maybe sparring, maybe doing stupid dominance displays again’ issues that they should probably have gotten past but they both have such forceful personalities and Gladio doesn’t back down and Ignis would but sometimes he wonders if that would insulting and…
Work. It takes work.
Being with Noctis isn’t as easy as being with Prompto for Gladio, but not as frustrating as Ignis tends to be. Noctis is just who he is, so nothing is ever easy with him. He’s set in his ways, so very set, and no alpha in the world can make him change at all. It’s his pack, he’s the head, and Gladio didn’t have issue with that when they were just packmates but he sometimes feels a little…inadequate once they start dating. (Ignis tells him he sometimes feels the same and that helps smooth it all over a little bit.)
Heats in general are…difficult. Ignis is always on hand for Noctis but there are times he’d like Gladio or Prompto around too. And Prompto is always down (Or up, rather) but Gladio finds it all very uncomfortable (maybe because of Ignis putting off all those alpha pheromones that he can’t help but feel a response to. Maybe just because heats in general are weird.) Prompto’s heats are slightly less awkward; he’s used to going it alone (his knotted dildo collection is awe inspiring actually) and if Gladio wants to help that’s fine and if not that’s also fine. He doesn’t ask Ignis to fill in and Ignis doesn’t offer. Eventually they’ll all work something out that works for everyone. Eventually.
Getting together a big unit is another things that takes time to get to. They’re together, all of them, but not ‘together’ for a while. It’s a subtle but very real difference, borne of venturing into all new territory and not being sure how to navigate it as a group of four instead of in groups of two or three. It turns out to be both different and not all that different at the same time. They get there though. The cuddle piles are pretty amazing.
