Hello all,

I am looking for a story that was probably written a couple years ago.  It was chaptered, probably around 40,000 words with about 14 chapters.  It was a Castiel/Dean endgame story, but I believe that it was told in such a way that each individual chapter was a little like an episode.  I'm pretty sure there was at least one chapter with Gabriel heavily featured, possibly more.  That chapter involved a hotel room and some kind of heist, so far as I can remember.  It was set sometime in season five.  One chapter, if I remember correctly, had Dean using Castiel's sword to fight something... I think it was angels?  I do remember either Dean or Castiel greatly balking at the idea of being in a homosexual relationship.  Any help you could provide would be greatly appreciated!

ETA: Thanks for the assistance.  The story was Immigrant Song. Thanks to acadine11 for finding it despite several of my memories being very wrong.
