Hi all,
I'm looking for a specific fic I read a while ago on AO3, it was Destiel, an AU where Dean was raised by John, and Sam by Mary. Mary and Sam thought Dean died I think, and then Sam meets Dean by chance at a friends house when he's in college, or something. They're still hunters in it, but John doesn't let Dean hunt, Dean does all the research for John-and lives in a small apartment by himself I think-I can't remember why, there was something unusual about Dean, possibly he was an Omega? Dean was just forming a relationship with Cas. When Mary comes to visit, she first disguises herself and observes Dean at the garage where he works, before meeting him at a family barbecue. I think Sam already knew Cas. Sorry, I know that's rather vague. I think it was a WIP, and it was quite long.

I'm also looking more generally for any fics that have Chuck in a fatherly role, particularly high school AUs where Cas' family take Dean in for whatever reason, and Chuck is a father figure, if such exist. Basically anything where Chuck is acting fatherly towards Cas and Dean by extension.
Thanks!!!
