Found! - Looking for a pre-series AU fic

[untiemybinds]

I'm looking for a fic where Castiel time travels (I think?), causing Henry Winchester to be let out just before John proposes to Mary and then Abaddon kills her parents? So John finds out about hunting and Mary, John, Castiel and Henry go into hiding in the Men of Letters Bunker for about ten years, raising Dean and Sam while there. Does anyone
