Dean: Don't normally see you off leash. Where's your boss?
Uriel: Castiel? Oh he's, he's not here. You see he has this weakness, he likes you.
From Castiel's first appearance in 4.01 Lazarus Rising, fandom saw the on-screen intensity between Dean Winchester and Castiel and took it further. It soon became a very popular pairing, with the first Dean/Castiel LiveJournal community appearing on 19th September 2008, the day after "Lazarus Rising" first aired. Its tagline is "Groped By An Angel". In May 2012 the community had 5774 members.
The first fics posted on Livejournal featuring Dean/Castiel were on 20th September 2008:
In the tradition of fandom making "mashup" pairing names, Dean/Castiel is usually referred to as Destiel (or rarely Dastiel).
Numerous allusions to the bond between Castiel and Dean in canon, often tied up with ribald sexual references, have delighted fans.
Castiel stares intently at Dean in silence
Dean: Cas, not for nothing, but the last time someone looked at me like that...I got laid.
Sam: So what, you like him better, or something?
Castiel: Dean and I do share a more profound bond. I wasn't going to mention it.
Balthazar: Sorry, you have me confused with the other angel. You know, the one in the dirty trench coat who's in love with you.
Dean: Why's it always got to be me that makes the call, huh? It's not like Cas lives in my ass. Dude's busy...
(Cas appears behind him) Cas, get out of my ass!Castiel: I was never in your...
Meg (to Dean): Ask him, he was your boyfriend first!
Castiel is usually written as topping when he’s being powerful angel, or as a bottom when the fic focuses on his sexual inexperience, especially losing his virginity to Dean. For more on these roles see Top/Bottom.
Like all Slash fictions, stories featuring Dean and Castiel in a relationship may cover any genre or kink including Future Fic, Pre-Series Fic, Crossover, Angst, Deathfic, Crack, Post-Apocalypse, Curtain Fic and Kid Fic. Hurt-Comfort especially involving whumped!Castiel and the appearance of the Magical Healing Cock are especially popular, as are and stories where Castiel discovers human emotions and sexual feelings for the first time. In AU fics, Castiel may be human rather than an angel.
Destiel outside fandom
Misha Collins mentioned fanfic and Dean/Castiel slash at several conventions. At the Salute to Supernatural Vancouver 2009, he said he'd heard about "Dean/Castiel/Pie fic". At Collectormania London 2009, he said he'd read some slash fanfic but "stopped at the part where Cas choked... on someone's cock". Source.
Salute to Supernatural Toronto 2011: When asked what had happened to Castiel's Trench Coat, Jared mimed Dean smelling and rubbing it all over himself. Jensen said, "He used it as a pillow — or as kindling. One of the two". Source.
As with Wincest, this pairing has been recognized in broader fandom — beyond fanfic authors and readers — including discussions on After Elton. In May 2011, Dean and Castiel won "TV's most romantic couple", beating out Kurt and Blaine from Glee in an online poll run by Spoiler TV.
At Comic Con 2012, a fan asked Jensen and Castiel what they thought of Destiel. Jensen asks the panel what it means (he thinks the fan says Deathsteel...).
Ben Edlund: "That's some weird shit."
Jensen: "Is this something that you created, Ben?"
Ben: "You don't want any part of that."
Jim Beaver: "It's...extreme bromance."
Ben: "There's a lot of pictures of Dean in an angelic embrace - and that's being kind of gentle with it."
Misha: "Oh that, love that. I mean (pointing to Jensen) you've got pictures like that of us, in an embrace, all over your bedroom."
Ben: "Oh there's a van with that airbrushed on the side."
Jensen: "Oh yeah it's my conversion van. It's just a nice airbrush a pillow in the back, there's not much room. Oh and a wolf howling at the moon.It's cool, you'll like it."
In September 2012 After Elton ran the reader-voted Ultimate Slash Madness Tourney. The final contestants were Destiel versus Sterek (aka Derek and Stiles from MTVs Teen Wolf) and the competition was fierce. Misha himself even got in on encouraging the voting, tweeting "This homonormative poll makes me sick! No one could seriously think that those Teen Wolf jerks are gayer than us".source
