Dean hasn't seen Sam in six weeks when they finally get an opportunity to get together to work on their father's battered Impala. Their daemons are curled up, their tools are ready, and the air opens and drops two more Winchesters in their lives. Only these two Winchesters do not have daemons. [takes place during Season 5 of SPN]

A glimpse into the childhood of Sam Winchester, and a moment of light. Spoiler free, because it's all original from my mind.

Sam and his dæmon patch Dean up after a hunt. Set mid season 3.

Though his dad would never say so, Dean suspected that his father let him come on his first salt-and-burn as a congratulations gift for his dæmon settling. And though Dean would never say so, it frightened the hell out of him. (Part of "The Rare One" universe; Day 1 of the 13 Days of Halloween Fic Writing Challenge.)

...And when we do find each other again, we'll cling together so tight that nothing and no one'll ever tear us apart. Every atom of me and every atom of you... A series of short stories concerning the crossover universe of Supernatural and His Dark Materials.

He stands alone, bitter from the love his father never gave him. He stands alone, draped in a trenchcoat and watching from afar. He stands alone, the only one in the world. He stands alone, except for the animal at his side.

The Apocalypse is averted. Lucifer and Michael are trapped in the Cage. Escape is impossible. Or is it?

When you're the kid with the unusual dæmon, it certainly raises a few questions. Sam Winchester has always been the rare one with the male dæmon, but one has to wonder when being an oddity stops being a coincidence. His Dark Materials AU

When Team Free Will finds an artifact from another world, they are thrust into an universe where souls take the form of animals, and their only allies are a detective, an army doctor, a madman with a box, a somewhat fussy angel and a fast-living demon.

Sam Winchester thinks Dr. Will Parry knows a lot more than he's letting on, Dean thinks he acts like Dr. Evil pretending Mr. Bigglesworth still had fur, and Will has no time for their shenanigans - he has a very important date.

A fusion between the characters of Supernatural and the world of His Dark Materials which spans most of Dean's life pre-series into a future past season four. Dean/Castiel
