*hugs* There's nothing wrong with becoming emotionally invested in the characters you love -- I do it all the time. Just don't make yourself TOO miserable. :)

I'm still holding out hope that Naomi is there to help and heal Castiel, rather than for more shady angelic shenanigans. (It would be most cool if she were actually God, finally returned home to fix both Castiel and the mess that Heaven has become.)

And you know? Sometimes, diverging from canon is what you've got to do -- sometimes fanfic is the only way to give your character what he really needs. Perhaps more cathartic conversations between Castiel and Inias need to be written . . . (and I know just the person to write them.) :)
