Hello, me again.

Specific fic: There's this alpha/omega style fic I started reading a week ago but forgot to bookmark, I think it may have been on AO3, and it had Dean, Cas, Charlie and I think someone named Gilda(?) where they were at some sort of omega resort, and Cas and Dean were in a relationship that their alphas' didn't know about. I think I got up to the point where Cas reveals his alpha has taken him off of birth control and Dean kinda freaks out a bit. That's all I can remember.

General searches:
1) Any alpha/omega style fics where Dean/Cas/Sam are omegas and have abusive alphas, with some hurt/comfort in there of course.

2) Fics where Cas has somehow become human and turns to Sam and Dean for help, but Dean (or Sam) decides they can't forgive him for the things he's done and abuses him in secret. (And I've already read Repent Of Your Sins (http://archiveofourown.org/works/1178489), which is what got me onto this in the first place.

I'd appreciate the help. Thanks guys.
