Hey,
I'm looking for a specific story where Dean and Cas have been a couple for several years, and at a family dinner Dean announces they are getting married, only to realize that everyone thought he and Cas were only roommates. Sam reacts the worst, I think. Also, Sam is engaged to Jess, who is pregnant, but later cheats on her with Ruby. I just remember that Jess moved in with Dean/Cas, and was suffering from severe morning sickness. Sorry, I know it's not much to go on.
Thanks, dc9
