Castiel Novak, 34, rich, translator, lonely and oh yeah... asexual. He's built up a life in solitude, working from home, enjoying the simple things in life.
However, something is missing in that life - a gap he doesn't know how to fill. The need to care, the need to provide.
There's just nobody that needs him. When he goes on a mandatory work trip, he finds someone that does.
Introducing Dean Winchester, 24, who suffers from involuntary age regression - making him a baby in an adult body whenever his brain feels like it, unable to take care of himself properly. Panic attacks, periods of regression and overall touch-starvation and loneliness has been his life for the past two years.
Fate had a hand in putting Dean's motel room next to Castiel's that day.

No Words

On the run from his very powerful family, Castiel does his best to get lost. Because if he doesn't know where he is, his brothers won't be able to find him very easily either. He ends up in Silverton, a small mountain town nestled deep within the Rocky Mountains where he meets Dean Winchester, a very beautiful and very grumpy omega.

Hunter at Heart, Hunter to the core

Henry never disappeared, John and then Sam and Dean are raised to be Men of Letters. Dean hates every single second of it - all he wants is to be a hunter. Men of Letters though look down on Hunters, and so Dean basically runs away from home to join an official Hunter office run by Bobby (basically he is Sam off to Stanford).
Years later Sam is sent to co-ordinate between the rising strength of the Hunters and the slowly fossilizing Men of Letters. It is not the easy job he thought it would be.
Dean is a whole new man. Will the family Winchester repair itself? Will Dean prove his worth? Will the hunters finally win the annual paint ball match against the cops? Wackiness and feelings will ensue.
