"What do you know about soul mates?" Castiel asked Dean walking in the room casually. Dean took his feet off of the table and turned to look at Castiel, his eyebrows raised?

"Of what?" he asked, thinking he'd misheard. Cas walked around the table and sat opposite Dean resting his legs on the table, much like Dean had been doing seconds before.

"Soul mates. They're less Christian lore, and more Greek. " he said rearranging his coat so it didn't slip off of his legs and make them cold; Sam was the only one who knew how to switch on the heating in the 'Batcave' and he was out looking for Garth who hadn't made contact in a few weeks, so Dean and Cas had to cope with the low draught that streamed through the main control rooms.

"Uh, not much." Dean said turning around and looking at Cas confused, he leant back in his chair, "All I know is there is supposed to be someone out there for everyone. Isn't that it really?" Cas laughed quietly,

"Its a bit more than that."He said almost mocking Dean, but in a less insulting tone. "Do you want me to explain it to you?" He asked.

Dean put his feet back on the table, settling into a more comfortable position. "I doubt you'd leave me alone even if I said no." he said, "So go on then."

Cas took his feet of the table and leant his elbows on the table, resting his chin on his hands. "In theory, all our souls are connected, to another persons. And that person is the perfect match of you -"

"Cas, why are you explaining this to me?" Dean interrupted.

"I'll tell you at the end." the angel said before continuing. "Anyway, supposedly this person is out there for you, and when you find them they are the perfect match to you. It doesn't always have to be a romantic attachment, it can just be close friends. But it is someone who you'd want to spend a lot of you time with, and probably the rest of your life around." He sat back in his chair. "This point is, I think I've found that person. With the help of the internet."

"Cas, me and Sam told you to stay away from those dating websites. They claim to be your soul mates and that they'll love you forever but they just want you for your good looks." Dean interrupted again.

"No, you explained to me quite thoroughly the problem with Stacey I was on a different website looking up information on what humans have been saying about Angels, and I stumbled upon a website that seemed to be blocked from Sam's ... iPad?" he paused for clarification, "IPad, yes, so I pressed lots of things until it let me on the website, tell Sam I'm sorry if I broke it. And the website was an author called Carver Edlund." Dean swore, "And his books, which its apparent that you know about. As I was going through the website, I found the Discussion board, and there was one that was titled... 'Destiel - Headcanon or Just Plain Canon?' and I read it, I wont tell you what it said but it talked about soul mates and such. I click a few of the links on there, and some of its... strange. But the more I read, not the weird stuff, the more things began to click together."

"I've heard of the weird crap fans of those books write. Just ignore all of it." Dean said, wary of what the angel would say next.

"Castiel stood up and looked down at Dean intensely, looking very much like the powerful, almighty angel he was.

"Dean," he said, his voice low and gravelly. "I think we are soul mates." Dean covered his mouth to suppress the loud, spit projecting laugh that was threatening to escape from his lips.

"Cas, man. Dont believe everything you real, especially on Chuck's website. All the people there are crazy, with a capital C." He leant over and clapped Cas on the shoulder. Cas looked at him confused,

"The people there were incredibly analytical. They took the scenes in the book we shared and read into it. They're very understanding of your problems that stem from an abusive childhood."

Dean spluttered, "Abusive?" he chocked.

"They seem to think that as your dad left you with Sam a lot when you were young and the way you acted around him in early books pointed to the conclusion that he was abusive. I'm not implying anything." Cas explained, his cheeks flushing a little as he realised that he's shocked and upset Dean a little.

"They don't know nothing." Dean mumbled, sliding down in his chair.

"In actual fact, they know quite a bit to be honest." Dean looked up and glared at Cas as he sat down on the edge of the table and looked down at at the man. Cas put his hands up in surrender "Okay, sorry, but either way. What they deduced from our interactions seem logical and plausible."

"Plausible?" Dean asked once again raising an eyebrow and sitting up a little straighter now that they'd gone off the subject of daddy-issues.

"You'd have to read it yourself to understand why its plausible. But I agree with it, and I'm kinda the older and wiser of the two of us. So I'm thinking we should do that thing couples you hiss at in the street do." Cas suggested innocently.

"Kissing?" Dean sounded past surprised. He sounded bewildered, and as Cas looked him in the face, could he detect a hint of 'holy-crap-I'm-out-of-my-depth' in his eyes.

"I s'pose there's only one way to find out if the Destiel.. shippers are right." he said as he slid across the table and leant in.
