Author's note that I should have put at the beginning of chapter one: This story is set during the Fourth Season of Supernatural, and somewhere between Small Favor and Turn Coat for the Dresden Files. Now on with the story.

&!&!&

It had been less than a second after the wizard? other magical being? made his statement about the fact that I and my brother didn't belong to this world that he looked me in the eyes as he gave a curious head tilt. Our gazes locked, one second, two, thr...damn, he didn't instinctively look away first like almost everyone else did on instinct...the Soulgaze was about to start, either I looked away now, or never...and...HOLY SHIT!

Never Soulgaze with an angel, it's about the most painful thing you can do with your Sight. I'm lucky my eyes didn't melt, and my brain didn't fry in the instant I got a look at that guy's true self. The fact that they hadn't is only down to the fact that Wizards are slightly hardier than normal people, and I had the sense to look away after less than half a second. All I can tell you about it is LIGHT! LIGHT! LIGHT! BURNS! BURNS! I thank all that is holy that I didn't try that with Uriel back home.

I must have passed out or something, because the next thing I knew, I was on the ground and Thomas was trying to get my attention. Considering the fact that I'd just gone through the psychic equivalent of being hit over the head with a tanker while staring directly at the sun while I was less than three feet away from it, that was completely understandable.

"The wizard and the vampire did not come here intentionally." the angel stated matter-of-factly.

The reaction this caused in the other two men was almost instantaneous. One second, the man who had walked up to us and started latching onto Thomas earlier had been looking at me in concern, and the next he had a gun on me, while the other man who was presumably Sam moved towards the open trunk of their car. In the short glimpse of the first man's green eyes that I got before I disconnected eye contact in order to not undergo another soulgaze and possibly finish killing myself, I noticed that they were hard and cold, and that something dark lurked behind them.

Thomas moved in front of me to protect me, while I called up a shield and drew my own gun. Something about this seemed to surprise the men, whether it was Thomas protecting me, or the fact that I'd pulled out a gun rather than attempt any spells, I do not know. Before the situation could deteriorate further however, the angel intervened.

"Dean, I cannot allow you to do this." The angel said, gripping Dean's gun hand and pulling it away. "The wizard is marked by the Heaven of his world."

That confused me for a moment, until I remembered that the Archangel Uriel had given me the ability to use Soulfire recently.

"There's more than one Heaven?" the man named Dean asked in surprise as he lowered his weapon, so it wouldn't accidentally go off and hurt someone he didn't mean to if the angel continued to push his hand.

"Yes and no." the angel replied.

"What is that supposed to mean?" Thomas asked.

"While each world has its own Heaven which is complete in and of itself, each Heaven is part of the infinite whole." the angel replied.

"I don't get it." Dean said.

"I think I do." the man who was presumably Sam - who had been in the process of rifling through a hidden compartment in the trunk of the Impala that contained a miniature armory - said. "It has to do with the Multiverse hypothesis. If everyone who died in every universe in the Multiverse went to the same place, it's possible that you would run into a trillion people who are you, but aren't you you, since the worlds they lived in and the decisions they made sent them down different paths. It was probably less stressful for everyone involved to divide the whole of Heaven up into infinite parts and build a Heaven for each universe so nobody ran into themselves, and suffered from the possible consequences."

"What possible consequences?" Dean asked.

"Would you be happy if you ran into a you who say, didn't make the deal to save me and consequently let me die, or a you who had never hunted because mom was still alive because I was never born?" the man that I was reasonably sure was Sam asked.

Dean's expression tightened at this. Clearly, the answer to both questions was no. In my opinion, Heaven would be a pretty miserable place if I ran the risk of running into versions of me who had made the right decision where I had made the wrong one. I could understand why the creator had kept things separate so that wouldn't happen.

"And no, I didn't get sidetracked." the man I was now certain was named Sam said as he brought up a crossbow and aimed it at Thomas. "There's still the vampire to deal with."

Fortunately, Thomas was standing close enough to me for me to bring up a shield around him as the man fired. Both Sam and Dean looked a little surprised when the arrow that looked like it had blood on the head hit nothing and bounced down to the ground. This shield was made to stop bullets, there was no way a measly arrow would get through.

"I would appreciate it if you didn't try to kill my brother." I said, as I pulled up the revolver which I still held, and aimed it at the man who had attempted to shoot Thomas.

Sam and Dean turned to look at each-other. "Brother?" Dean mouthed. Sam looked at us with an expression of pity, and dropped the crossbow back into the trunk clearly realizing that killing Thomas wasn't worth getting himself and/or his brother killed.

&!&!&

Dean stared at the two brothers and wondered if that could have ended up being him and Sammy after a hunt gone bad. Looking more closely at the two men, he could see the resemblance that he'd almost thought was a coincidence earlier, and that it wasn't as vague as he'd idly noted when he'd first spotted the two men. There was something about the shapes of their faces and their bone structure that was similar despite the fact that one was a wiry beanpole with a slightly hawkish profile, and the other was six inches shorter and rather muscular with more aristocratic features. Both men also had dark hair. One with a really dark muddy brown head of hair that was almost black, and the other with a head of hair that was raven wing black with a set of almost impossible iridescent highlights. He had the feeling that he and Sam weren't the only set of siblings that frequently got mistaken for a gay couple.

Would he have hung around if Sam was turned into a vampire, or would he have found it within himself to kill his brother as he had been unable to do when Meg had possessed him and attempted to goad him into doing so? He could totally see himself trying to find a spell or potion or something that would keep Sam Sam after he turned, if he were in the other man's position. He had once spared a group of vampires who had done their best not to be human killing monsters before at Sam's behest, so why not spare Sam if something similar came to pass?

The whole Wizard and Vampire from another world thing wasn't something he could quite wrap his head around, but he could understand a pair of brothers looking out for each-other. The wizard couldn't be that bad, considering the fact that he'd been marked by heaven, but then again, besides Castiel, the other angels he and Sam had encountered so far had been dicks. He wouldn't put it past them to recruit a guy who had made a deal for power and come to regret it, and chuck him aside when they were done with him.

"So," Dean said as his brain latched onto something familiar, and brought him back to earth, something that had to do with the job he'd came here for, a job that the wizard and the vampire had inadvertently butted into. "What were you saying about a troll earlier?"

"Huh?" the tall one who was standing protectively in front of his vampire brother who was putting out more charm than John Wellington Wells during an inventory reduction sale said eloquently, looking completely thrown for a loop.

Damn. He'd thought that he'd forgotten about that stupid Gilbert and Sullivan song. He was going to kill Sam for that, and then he was going to kill the vampire for earlier as soon as he was certain that the wizard wouldn't suspect him and blow him to kingdom come, either his, or the wizard's.

"The hunt." Dean said, deciding to continue defusing the situation before it got any uglier. The angel had clearly stated that the wizard was off limits, and the wizard had made it clear that the vampire who was rather oddly not weakened by the sunlight was off limits as well unless he and Sammy wanted to get their heads blown off.

"Hunt?" both the wizard and his vampire brother said at the same time, looking at each-other in confusion.

"You know what? Forget it." Dean said as he grabbed his "Federal Agent" suit and walked back to his room to change, with Sammy following after after slamming and locking the Impala's trunk.

As far as Dean was concerned, if he ever saw those two again, it would be too soon. Hopefully, they'd go back to their own world quickly, and he'd never have to deal with them again. Knowing his and Sam's luck however, he had a sneaking suspicion that that was not to be.

&!&!&!&

Castiel studied the two that had accidentally entered their world through the realm of the Faerie which spanned across a number of the worlds. While on the surface it appeared to be an accident, he couldn't rule out the possibility that the heaven of their world was interfering somehow, despite the fact that they weren't supposed to, as each world had its own fate which wasn't to be messed with. The two men were similar to Sam and Dean in a number of ways, and being like Sam and Dean, they could disrupt any number of plans, and interfere with fate in ways they were never meant to.
