Demon!Dean/Fallen!Castiel

[joidianne4eva]

Hi guys

I'm looking for a fic that I read a while back it was a Dean/Cas fic. Castiel was in hell with Dean for some reason. They broke out off hell but Dean was a demon and Castiel was either a demon too or fallen. I remember that they were watching over Sam at one point and I think they killed Ruby.

Any help would be appreciated!
