In Which The Fourth Wall Does Not Exist
It all starts when Dean, unable to wrap his head around it, begins researching Wincest. For no reason. At all. Really. He was Not Morbidly Curious. Really. Sam, who is already disturbed plenty from the first, initial encounter, ignores his older brother's increasing fascination with the Supernatural fandom.
Any exchanges on the matter usually go down similar veins:
"God, fangirls are creepy as hell." Dean would mutter.
"Yeah, yeah they are." Sam would reply, not even encouraging his brother to share the trauma or telling his to get off. Dean would either be all too happy to share or want to protect his baby brother's mind on the first count and the second would be ignored.
That was all before Hell tough. And before they had an angle with them on occasion.
One thing was clear in both brothers' minds, however–protect Castiel from the horrors of fangirls and the Supernatural fandom. Dean will still look into it whenever he has a free moment to spare and Sam will still ignore it, but Dean stops the comments. Castiel may not care that Dean has a strange fixation on a fandom that is based off of his brother and his adventures, but Dean doesn't want the angel to lose all faith he has in humanity due to finding out that fangirls are stalkerish nut balls that like to slash Dean and his brother at every opportunity.
All goes well in this plan of action. Until the day Dean first sees Cas/Dean.
On that day, it is a relatively calm day. Sam is instructing the angel on the finer points of human interaction and Dean is on the computer.
Castiel had been known to the fandom for some time now. It wasn't too bad. They tend to like him, actually. Unfortunately, this meant that he gets tortured mercilessly in their writings. Dean had actually been looking at a bunch that ran along the same vein as that when he spotted it.
And he promptly launches himself out of his chair yelling and cursing a blue streak.
When Castiel goes to see what caused the hunter to launch himself out of his own chair, Dean, grabbed the computer and shut it down.
He tells Sam later, and claims the Most Abused by Fandom prize for a whole week. Right up until he finds that some sadist had put a gargoyle curse on his baby brother and is making him die via turning stone. After that, Sam get's the prize back
For his part, Castiel doesn't see what's so bad about Supernatural. Then again, he also doesn't know what fangirls are capable of.
It takes two weeks of both hunters actively hiding the fandom from him for the angel to get fed up. When he's not with them the next time, he goes to find out about the Supernatural fandom.
When they see him next, the first words out of his mouth are "They do know you two are brothers and that that is a sin right? And that there isn't anything between Dean and I?" he's confused when Sam storms away to get brain bleach–again–and Dean just takes him back to the small motel room they're staying in for the night to explain.
He tells Castiel that, yes, the fangirls know that, canonically, neither pairing is true. The thing is, they don't care. At all.
In fact, it seems that telling them so and trying to enforce it only encourages them.
After that, both Dean and Castiel look into the Supernatural fandom a lot. Sam still ignores it. Dean still makes comments. But now, Castiel makes comments too. And they find that that's not too bad.
Its one particular comment, from Dean no less, which finally gets Sam to look into the fandom as well. Just to know.
"You know, I think Hell could take a few lessons from some of these girls."
I do not like this part much. but I figure it goes well with the second part.
Also, I adore the episode in the fourth season: The Monster at the End of This Book. it breaches the fourth wall so.
