"One more thing Dean" Cas's gravelly voice came through on the phone, the boys were driving the Impala back to the bunker after finishing a dead end case, and Cas had called with an update.

"Hmm?" Dean mumbled, he was driving with one hand on the wheel and using the other to stuff a bacon cheese burger into his mouth.

"I've been doing some research on the Supernatural fan sites, reading some of the, uh, fan theories"

"WHAT?" Dean yelled choking on his food, "Why the hell would you do that?"

"Actually it's not a bad idea" Sam mused, as Dean glared at him he tried to explain "We've hit a dead end, at this point any lead would help, and since the books are literally about our lives maybe some of the fans have a clue at where this goes next"

Dean sighed "Find anything?"

"Well, not exactly" Cas hesitated, "I'm finding it challenging interpreting some of the language used, I am unfamiliar with an otp, and I cannot understand the obsession over boating"

"Otp means one true pairing, like the couple they want to be together, like Johnlock" Sam began explaining and stopped at the incredulous expression on Deans face

"What?" Dean and Cas said at the same time

"Uh, nothing, never mind, I don't know what the boating is about though"

"There was a lot of mentions about ships and shipping"

Sam coughed back a laugh "Uh, look Cas, don't worry about it, there is some pretty wacky stuff on those sites, have you found anything else?"

"Who is Destiel?" he asked, the word sounded foreign on his lips

Sam burst out laughing and Dean choked almost losing control of the car, it took him a minute to recover before he could respond

"Cas, promise me something" Dean growled, shooting a murderous look at Sam and taking the phone off of speaker.

"Yes, Dean, what can I do?"

"Do. Not. Ever. Look. Up. Destiel." Dean spat out over the sound of Sam's laughter. He could picture Cas's head tilting to the side in confusion and his intense stare and was suddenly grateful they were having this conversation over the phone as he didn't think he would be able to maintain eye contact right now.

"Dean, what is it?"

"Look Cas you just gotta trust me on this one, pretend you never saw it, and stay off those damn sites, Sam and I can see if they have anything useful, though I seriously doubt it, ok?" Dean said, then hung up before Sam had time to say anything stupid.

"You know you're not gonna be able to keep it from him forever"

"Shut up" Dean growled and turning up the radio and pressing down on the gas.

Cas stood in the bunker, with piles of books lying on the tables around him and a laptop open to a supernatural fan page. Dean had hung up on him but that was nothing new, what was bothering him was this mysterious Destiel. Cas wondered if it was a demon he had not heard of, but that would not explain Sam's laughter and the reaction of the people on the fan site. They seemed to either love or hate him and mostly argued about his existence. Dean had made him promise not to look it up online but there was another source he could question.

Chuck was sitting at his desk in boxers and a grubby shirt he probably hadn't changed for days, not that he could remember. There were empty booze bottles laying haphazardly around the room and the stench of despair hung in the air. Chuck scratched at his head and leaned back, he had just finished another chapter, recounting the visions he had seen last week, he stood up stretching and made his way to the kitchen, frowning over the contents in the fridge. "Pizza it is" he thought without much joy and reached in for the last of his beer making a mental note to pick up some more. He stood up shutting the fridge and almost dropped the bottle

"Ah, jeez Cas, can't you knock?"

"Chuck I have some questions"

"What is it this time?" Chuck groaned, he was really starting to get tired of being a prophet.

"Who is Destiel?" This time Chuck did drop the beer and it broke as it hit the tiles of the floor spraying beer onto Cas's trench coat.

"And why does he invoke such extreme reactions from people?"

"Wow, ok, look Cas, I wasn't expecting this, maybe you should, uh, go talk to Sam and Dean"

"I tried. Dean got quite angry and Sam just laughed"

"Ah, right, are you sure you want to know this?"

"Yes" Cas said it so firmly that for a minute Chuck remembered he was an angel of the lord

"Well, my books have a pretty, um, creative fan base and they like to interpret certain things that are not explicitly written in the text"

"Yes, I was looking into their fan theories as possible leads for what to do next"

"Huh, not a bad idea actually, well some of them believe that there is more to some of the characters' relationships than what is written, subtext if you will, they feel some of the characters belong together, romantically I mean"

"What does this have to do with Destiel?"

"Uh, well, when they talk about two people being together they sometimes combine their names and refer to the couple as one entity, so that's what Destiel is" Chuck finished lamely.

Cas frowned at him, "I'm not following"

Chuck cringed as he realized that being subtle was not going to get through to Cas. "Destiel is the combination of two names, the fans refer to the pairing of you, Castiel, with Dean as Destiel"

Chuck watched as Cas processed what he had said

"so they mean-"

"Yes"

"Together?"

"Yup"

"It doesn't make sense... shouldn't it be 'Deastiel'?"
