I'm looking for a specific story I read a while ago when I just started out in the fandom and really liked but haven't saved or bookmarked and now I can't find it anymore. I most likely read it on AO3, maybe FF.net.

It was a Team Free Will + Bobby fic; either completely Gen or very mildly Wincestiel / Destiel.
It was set sometime in season 6, I think, and Castiel had been hurt badly during his conflict with Raphael, and the Winchesters took care of him at Bobby's house. I read it before watching season 6, but I remember that though it didn't really give away any plot points, it heavily alluded to the fact that Castiel had never been told by Dean / the Winchesters that he was like family - they do during the fic, but while he is unconscious, and I remember quite clearly that the fic stated that the next time he was told it was too late (i.e. referencing the end of the season) - I think that was one of the final lines?

Sound familiar?
