Back again! I read a fic a few months back where Castiel and Uriel got into an argument over whether Sam and Dean being together was a sin. Uriel said it was, but Castiel maintained that it was love and that they were soulmates, which made it okay.

So it became this kind of get-Job-to-curse-me-and-die challenge where Cas allowed Uriel to put the Winchesters into alternate universes and see if they would find each other and fall in love, or if what they had was just lust. 

In one universe Dean was a truck driver and Sam was a hitchhiker, in another Dean was a rebel fighter and Sam was a reporter covering his story. One was cop!Dean and cat-burglar!Sam, and one was based off the Jen/Fuzzy storyline in Ten Inch Hero. There was even one where Dean was in the role of Denny from Grey's Anatomy and Sam was his Izzie. 

It was a really great fic, but I cannot find it anywhere! Does anyone happen to know where I might locate it?

Update: FOUND! 100% Reason to Remember.
