A/N: Hi guys! So, I've been working on my Gilmore Girls story quite allot lately so I decided to give myself a break and write my first ever SPN one! And, of course, it has to be about my favorite pairing! Destiel x

Chapter one: What does it do?

Dean sat on the scratchy bed of his and Sam's crappy motel room, wondering what do to. Something was going on here; he could feel it, especially after the very disturbing conversation with Bobby. Then he had an idea.

Cas! He'll be able to figure out what's going on here! He pulled out his cell before realizing what he was doing and slipping it back into his pocket.

God, I always feel ridiculous doing this. "Castiel! We err... Could really use you're help right now, something weird is going down and... Well... it sort of feels like you're area of expertise so... if you're not too busy, you think maybe you could pop down and give us a hand figuring it out..." He opened one eye to peek out and saw the room was still empty. He sighed and got up to pace around. When he got to the edge of the room he turned and almost walked straight into Castiel.

"Oh god, man you almost gave me a heart attack! Why the hell do you have to be so quiet? You became a Heavenly Ninja or something?" He ranted clutching his chest.

"My apologies." Dean could tell Castiel wasn't really bothered so he let it go. He moved around him to sit back down on the edge of bed, Castiel followed and stood in front of him. Dean gestured with a wave of his hand for him to sit on Sam's bed but he ignored it or didn't understand. Either way he remained standing.

"What do you mean? 'Feels like you're area of expertise'?" He asked, clearly not interested in small talk or pleasantries.

"Well, you know all the Angel-nukes are all over the place? This sort of feels like it could be one of them," Dean replied. He quickly briefed Castiel on what was happening and asked what he thought. At some point Castiel had drifted over to Sam's bed and was perched on the edge, leaning his elbows on his knees with his hands clasped in front of him and Dean had moved round so they were both facing each other. When he was finished Castiel sat completely still and quiet for a few moments. After a while, Dean became restless and tried to prompt him into speaking by saying, "Cas? Hello? Earth to Cas, what do you think? Is it angelic or what?" He still didn't speak. Dean blinked and he was gone.

Damnit! Why did he keep doing that? It was so annoying!

Just as Dean was about to stand up, Castiel reappeared in the same spot and position he had been in before, as if he'd never left, only now he was inspection a long thin horn with a wide end and a thin end, like the horns they used to blow when the king arrived in medieval times, only smaller and more hand-held. He was turning it in his hands and studying it very intently.

"Is that it? What does it do?" Dean asked, he couldn't help it; his curiosity got the better of him as it usually did when it came to weird and unusual things.

"Basically, when someone asks for the truth, the horn is blown and everyone who speaks to that person must tell them the truth no matter what they ask, or how badly they don't want to tell it. It is usually blown by an angel in heaven who watches out for people who ask but not necessarily Gabriel because, well, as you know he is... unavailable." He looked down when he said that, as if he actually cared that Lucifer had killed Gabriel.

"So someone blows the horn and suddenly everyone spills their guts to 'em? Well, that sucks. How do we stop it, or can we at all?" Dean summarized. Castiel though for a moment then said, "I'll find out," before disappearing again with the horn. Dean sighed and turned to the TV, pressed the 'on' button on the remote and tuned into "Doctor Sexy M.D". He still had a while before Sam would be back from the library or wherever he was.

A/N2: Hope you liked it, Reviews are like love, please give me them. Sorry it's a little slow to start up but they'll be plenty more Destiel in later chapters, not worry. X
