Summary: Dean slowly loses his memories.
Occasionally, when Dean catches a glimpse of beige coat or dark, rumpled hair, he has to remind himself that He — whoever it might have been — is gone. Dean doesn't remember His name or any other significant detail other than it's a man. Not anymore. He doesn't remember when he started to lose bits and pieces of his memories. Every day he can summon less and less fragments of his past. It should be troubling him, but it isn't; he should be terrified, but instead, he feels calm. He heard from someone he can no longer recall that oblivion is as close to happiness as anything can ever get. Sometimes he wonders who he is missing and why, but mostly, he doesn't bother with useless questions. After all, he has a life to live and work to do. Dean knows, one morning he will wake up and not remember that he forgot something at all. He's waiting for that moment.
Somewhere in a room that is not a room, at another plane of existence, a person, who looks like a middle aged businessman but is not, in fact, human, grins a shark's smile, satisfied. "Now, when Sam said 'yes' to Lucifer and we have Adam, we can finally bring Paradise to Earth," he says to his brothers.
