A/N: So, I don't really know why I did this. I got bored I guess. If you review, it doesn't actually gain you anything, but it makes me very happy. :D

The Doctor gr inned. "You're in my TARDIS," he said proudly. "Stands for Time and Relative Dimensions In Space. It can go anywhere in space and time, anywhere and everywhere you like." He was obviously expecting the two newcomers to be impressed.

The shorter of the two pulled out a gun and levelled it at the Doctor's head.

"Dean!" chided the taller of the two. "Put the gun away."

"Hell no Sammy. Not until I know what the fuck is going on here. Is it the angels? It's the angels, isn't it? Gabriel probably, the little shit."

"Angels." Rory muttered, more to himself than to anyone else. "Great. Now we've got angels to deal with."

"Put the gun down sweetheart," said River softly, her own gun pointed directly at Sam. "If you harm my husband, it will be the last thing your friend here ever sees you do. And I should warn you, I'm an excellent shot."

Dean had been up against all kinds of hell. From vampires to gods to Lucifer to shapeshifters, he'd seen it all. Yet, somehow, this lady with the big hair and the gun was more intimidating than them all. He scowled and slowly lowered his gun to the floor.

"Further." River ordered.

Dean sighed and kicked the gun halfway across the floor. "Happy?"

"No guns", commented the Doctor.

"'Scuse me?"

"I don't do guns, fullstop. So no guns."

Amy cleared her throat. "Well, how about we introduce ourselves? She turned to the taller, calmer man and gave him her best I-know-the-company-I-keep-is-weird-but-I'm-a-nice- person smile. "I'm Amy, Amy Pond."

"Sam Winchester," he said, shaking her hand. "And this is my brother Dean."

"Older brother," muttered Dean.

Amy couldn't help but notice they were both equally hot. "This is Rory Williams-"

"Her husband," Rory cut in.

Amy continued as if there had been no interruption, "and this is the Doctor and River Song."

"Alright, great you're all British and have weird names, now want to hell us what the hell this is all about?" Dean snapped.

"What are you anyway?" The Doctor enquired, ignoring Dean's queries. "Human?"

"Huma- what of course we're human!"

"Really? Because the TARDIS is picking up something that's not all human. From your brother."

Dean scowled. "Well you can tell your stupid TARDIS to shut the hell up because Sammy's just as good as any human, better all of them anyway."

The Doctor shrugged. "Never said he wasn't. But who are we to judge if he's not fully human? Is there a person in this room who can say they were always a full human?"

"I was plastic once." Rory offered.

"I was just some flesh one time." Amy pointed out.

"I was born only part human." River added.

"And I'm not human at all." The Doctor concluded.

Dean appeared to be slightly dumbfounded. "Well, would you look at that Sammy? Seems like we've stumbled onto a group of freaks just as freaky as ourselves."

Sam smiled wanly. "Never thought I'd see the day."

"So who are you then?" Amy asked casually. "What are you for that matter?"

Dean decided to take a wild leap and trust the young and attractive, red-headed Scottish woman. "We're hunters. We kill all the big baddies in the world, make sure all the kiddies and adults too can sleep better at night." He noticed the Doctor's expression of distaste. "You gotta problem with hunters?"

"More than one," the Doctor said quietly. Dean fell silent.

Sam picked up where his brother left off, "Well, uh, can you try and explain what's going on?"

"Ever hear of a guy named Loki?" River asked.

"Loki? Yeah, it rings a bell." Dean said.

"Well, let's get down to the basics. Do you understand that there's more than one reality?" Dean and Sam nodded. "Well, in a different reality, one of which none of us are from, a god named Loki is using this-" she gestured towards the Tesseract, which neither Dean nor Sam had noticed until she pointed it out – "To take over Earth in that reality. He somehow used its power to rewrite reality, which put him on the throne, Earth under his rule, and the people who oppressed him in chains. So I did what needed doing."

"Which was?" Sam asked, deciding he liked River.

"I got a Dimension Jumper, from the same gorgeous time agent who provided me with my Vortex Manipulator. I stole Loki's Tesseract, but he noticed unfortunately."

"And now he's trying to get it back," Sam said, with a nod, "But where do Dean and I come into in all of this?"

"Loki tore a hole in the fabric of his reality and ours," the Doctor explained, speaking for the first time in what was a long time to pass, without hearing the Doctor's intone. "Other, smaller tears started ripping in realities such as yours. Therefore, you fell straight into our reality. There are probably others, just like you, thrown into the wrong world."

Dean caught Sam's eye and appeared to exchange a silent conversation through a quick glance. Sam nodded.

"Cas?" Dean said, seemingly to nobody. "Look, we're really screwed up here and we could do with your help. So, uh, if you could maybe get down here somehow that would be great, man."

"Your friend won't be able to make it Dean," the Doctor said, apologetically, apparently having got past his dislike of Dean's job. "Nobody can just jump through such small cracks at will."

Dean smirked. "Look behind you Bowties."

"I don't understand," said a new, deeper voice. "Why would you refer to somebody by the name of an unusual accessory they adorn themselves with?"

The Doctor looked baffled, for once in 900 years. "I – how – what – how did he get here when you called? That's impossible."

"Who are you anyway?" Amy asked, taken aback by the strange turn on events.

The newcomer, yet another attractive young man, this one in a trenchcoat instead of plaid introduced himself to the Timelord. "I'm Castiel. I'm an angel of the Lord."
