all the fic I wanted to write but didn't

Sam and Dean wake up with no memories but they're checked into a motel with a single king sized bed and they feel awfully close so they figure they're a couple and there's obviously some case that makes it look like they're just on holiday but they don't know that and they get fleshy and then they find a hex bag and decide it's gross so throw it on the fire and get their memories back.
