I'm looking for a dean/John specific verse, it's the dark!verse, but it seems like I lost the link and I can't even remember who wrote it or where!!

It's about Dean, who has been keeping secrets from Dad and Sam, he steals oxi from the first aid kit and John notices when he doesn't find enough pills for other hunter, Dean's left school two years prior, and I believe has been doing other stuff, stealing and gambling and even prostitution to pay for his habit; John sends Sam away to deal with Dean's detox, and during that period there's some sex(?) frotage.
we get to see the future where Dean Crashes at Sam's stanford apartment, all beaten up and tells him he has a son, and that he's gay and that he's been dating someone, and we kinda get to understand it was John... that's where I lost it...

anyone? please?
