How (thanks to Gabriel) Dean and Cas (accidentally) raised each other (and Sam)

In which, Gabriel meddles with the time line and Castiel becomes Dean's angel rather sooner than intended.

What if Dean went to Sam at Stanford for help trying to find their father, and Sam said no?

Written for this prompt by deceptivechasm on the no longer exists LJ simon_says_dean: Something very traumatic happens to Dean while he's with Sam (or Sam was away) which causes him to stop talking, *again*. Sam didn't know about the first time, and has to ask Bobby (or John) about what happened after his mum died. She originally requested Gen or Wincest but okayed my going with Dean/Cas instead. As implied in the note below this was written before we knew about the whole Souless-Sam thing.

The four Horsemen are not just people with fancy rings. They aren’t even demons with fancy rings. They are another species entirely, a force unto themselves, and Lucifer is kidding himself if he thinks that they are at his beck and call. They are separate. They are neutral. Dean Winchester is not built like them.

Are you there, Dean Winchester? It's me ... God

Dean Winchester has grown used to God dicking around in his life the last couple years. But this crap? This takes the CAKE ... or pie, rather. Now he's been thrown a whole new curve-ball. The kind that has ended the Civil War in Heaven ... but resulted in Raphael taking over, and hunting for Dean's ass on a silver platter. Not to mention dealing with Balthazar acting like a self-righteous prick, Sam having some big damn epiphany on his big brother's sexuality, and Cas eying him up like he's the world's juiciest cheeseburger. All that mixed with the chance to fix it all and set everything to rights ... but only if Dean is willing to sacrifice himself. Again. Seriously, if he ever meets that bastard God he's gonna- ... oh hey, Chuck! What are you doing here?

sympathy for the devil

After the final Seal is broken, Dean discovers that he's actually Lucifer. He's not really sure how he feels about that.

the best years of our lives, my ass

AU after Season 8, episode 6, "Southern Comfort." Dean goes to sleep in a motel room in Texarkana, and he wakes up 17 years old, in his childhood bedroom in Lawrence, Kansas, 1996. He has no idea how he got there, why his parents are still alive, why his brother is an adorable freshman with no memory of his adult life, and why the only ally he has in this place is the angel he left behind in Purgatory – somehow also 17 years old. They have to get out, that's the important thing. Only, falling in love with his angel wasn't a part of the plan....

what I need

A joking phrase commonly heard between a surgeon and his tech is "Give me what I need, not what I ask for." Dr. Novak and his tech Dean will soon learn the impact this phrase has on life outside the operating room.

cursed or not
http://archiveofourown.org/works/1792741?view_full_work=true
While experimenting with magic when he was a kid, Sam accidentally cursed Dean. Now, Dean is forced to wear a spelled amulet constantly, or he'll turn into a random animal. For a little over a decade, he's learned to live with the curse, and has even found it useful in some cases, but he sure would be happier without it.

When he meets a witch named Castiel, he's offered a deal. Instead of assuming all witches are bad, Dean can spend a season getting to know him. If at the end of the season, Dean still thinks he's evil Castiel will send him away with his memory wiped of the whole experience. But if he learns that Castiel is not the monster Dean assumes he is, he'll lift Dean's curse.

It's an offer Dean can't bring himself to pass up.

what has eight tentacles and isn't allowed to eat pie?

Dean watched an anime porn about this once, but real life turns out to be way less interesting.

Or, the one where Dean gets turned into an octopus.

I hope you haven't read all of them yet. Enjoy!

Shortskirts 'Verse by twentysomething. http://archiveofourown.org/works/154453/chapters/221971

Excerpts From Carver Edlund's Magnum Opus by twentysomething. Summary: ""C'mon, Cas, it's like we're Mulder and Scully, this is totally X-Files," he says expansively, waving a hand around. It makes his tie flap and momentarily obscure the new and distracting belt buckle that just says "LUCKY" in huge, embarrassing reflective script in the early morning light. Castiel just stares blankly at him."" This is a Bones fusion where Dean is Booth and Cas is Bones.

Asunder by rageprufrock. Summary: It's going to be a shitty wedding with shitty people and a shitty atmosphere and Dean feels shitty about going.
But first Jo, and then Ellen, and then Bobby had called in quick succession and informed him — in order — that they had ordered his ass a plane ticket, called him a rental car from the airport, and that he was showing up or so God help him.

Convenient Husbands by Annie D (scaramouche). Summary: "It's only temporary, right?" Dean says. "Just until you're healed up, and then we'll never have to see each other again. So what do you say, Castiel, do you want to marry me or not?"
