Thank you! I'd had the idea of Jamie in my head for a long time, but I didn't have a good enough reason for the apocalypse (and Jamie was still just the girl sitting on the hood of a Dodge as Dean drove down the highway outside Indy). And then AHBL came, and as I was working on the story I realized the solution was simple: Dean didn't make the deal, and so came the apocalypse.

And yes, Dean's POV on the next part of the story is in the works already. :)
