Hi,

I'd read a fic a while ago set immediately after the end of season 4, right after the cage opens.  Except, it's not Lucifer that pops out of the cage; it's just Sam's Grace.  Sam had been Lucifer all along, had been living through one human incarnation after another over the millennium.  And now that he's completely himself again, he's still just Sam.  Doesn't have any interest in destroying the world.  I think there might've been Wincest in this, but I'm a little vague on how the story ended.

Thanks!
