I don’t think it’s rude at all! Headcanons are headcanons for a reason. @nightmares06 writes Dean as straight and Stan is in a relationship by the time they meet in Brothers Consulted, so they won’t end up a couple at all in our stories, but it’s perfectly fine to think up your own versions of the story as long as you don’t demand we make it canon.
I can’t wait to write about Stan and Nathan, though. Nate’s just the right amount of chill to go along with whatever shenanigans his secret agent brings home.
Aww! XD Stan and Dean are at the very least, the brotp of the AU.
While in BC canon, Stan is certainly head over heels for Nathan, there’s no denying Dean’s natural charm. He would respect their size differences, and of course Dean’s own preference for women (In BAverse canon, he remains straight).
If Dean found himself at the same height as Stan, and Stan was unattached, Dean might have a fiery redhead crushing on him for a bit XD Stan falling a bit for that natural charm before they manage to untangle it.
We did make a few ship names for them XD You’re not the only one that loves those two dorks. (St)an and D(ean) for Stean, and (Win)chester and Ba(ker) for Winker. Which do you guys like? Any other ideas?
