Hi!
So I've been kicking myself trying to find this story, and it's a no-go far - so some help would be great!

basically, I found it on LJ, I think, and the tital was in Latin. I think it might have started with an F or a T. It was pretty long, from what I remember, and set in season 7. Basically, the entire premise was that Sam was continually hallucinating Lucifier as well as developing a fixation with doing things in threes. Things like three showers a day, only eating dinner before five, always doing laundry on Saturdays, I think, even if they were in the middle of a case. In the beginning on the story, on a case, he ended up getting burned while on a hunt for a witch. He ended up grabbing a red-hot medallion and the words, something religious in Latin, got seared onto his palm.

There's an entire scene of the Winchesters buying pens in a Staples, basically, and Sam being super picky about it - how many black pens vs. blue - and it not being played for laughs.

At some pointt some point, Sam was kidnapped by Crowley and chained to a pipe in some warehouse, arms above his head. Crowlery tortures him a bit, but the thing that bothers sam (and Lucifer) more is the fact that there's a puzzle/crossword book laying crumpled on the floor).

Pairing were sort of a back-seat, but I remember that there was wincest and maybe implised Lucifer/Sam?

Thanks for the help, guys.
