Author's note: hey there, this is my first fanfic so please bear with me. But I'm VERY excited to have this published, so thank you for reading. This takes place a few weeks after Amy and Rory get zapped by the Weeping Angels. But right after 'The Girl with the Dungeon's and Dragon's Tattoo' on Supernatural.

*There will be season 9 and 10 spoilers of Supernatural*

(I don't own any Doctor Who, Supernatural or Sherlock characters)

Sam tapped on his laptop that was on the table. "Hey Dean, check this out." "Wha?" His brother stuffed his face with a Philly Chesse-steak sandwich. "There were some murders in London and the victims were electrocuted. Now one saw what happened and there weren't any traces of anybody being there except the victims. That morning a man called the police. The victims weren't connected either. In fact, none of them are in any records; no jobs, no families, no birth certificates, nothing that shows they ever existed. Three women and two men; one Harriet Jones and the others were unidentifiable." Sam said, Dean chewed loudly on his sandwich, Sam looked at him. Dean swallowed, "No. We're going to London? The place with tea and biscuits and bad weather? That London?" Sam stood up and went over to the bed and took out both of their bags saying, "We have to, it's our job." His brother turned in his chair, "Since when the hell have you cared that it's our job?" He ignored Dean's question and said, "Either way, we're going. A friend of Bobby's emailed me and said they heard that The Colt was there." Dean sighed and gritted his teeth, "Fine."

Dean walked around his car and froze then said, "Wait, what about Baby?" He ran a gentle hand across the top of his Impala. "I guess we'll have to leave her at a storage—" "Nope." Dean said quickly. "Then we could leave her with Chuck." Sam suggested. His brother sighed heavily and got behind the wheel and slammed the door. "Fine." Sam got into the car and Dean pulled out of the motel parking lot. "So this hunter I found a few months ago—" "And now you tell me? What if he's like Gordon?" Sam ignored the question and continued, "her name is (y/n) (y/l/n)." He turned his laptop to Dean. His brother grinned and said, "She's hot." "Why do you sound so surprised?" Sam asked, closing his computer. "Well usually friend's of Bobby's are old." Sam smiled at that and shook his head.

They drove to the airport and parked, "No! Aw, come on! Why are we flying? Don't you remember what happened last time we were on a plane?" "How did you think we were going to get there?" "I don't know, by boat?" Dean said, then heard a knock on the window; it was Chuck. The brothers got out of the car, "Hey, Chuck." Sam went around to greet his friend. "Hey." He said, looking at the Winchesters. Dean looked at the prophet and hesitantly put his keys in his hand, "If you get one scratch on her I will personally kick you in the ass and there's not a damn thing Michael can do about it." Dean threatened. Chuck nodded and got into the driver's seat and backed up into the street and left the airport. Dean gave a small wave back to his car before entering the airport.

The airplane taxied around the runway. Sam looked out the window as Dean fiddled with the air conditioning. "Dean! Cut it out!" Sam said. His brother looked down the aisle as a cute flight attendant with blonde hair showed the passengers how to use the oxygen masks, he raised his eyebrows. But then a man wearing a fez blocked Dean's view. He elbowed Sam and said, "Who wears a fez these days?" Sam shook his head and looked at his father's notebook.

"Any leads?" "Angels. Specifically Rapheal. He has the power over electricity." Sam told him. Dean threw his hands in the air saying, "Great. The last thing we need is a freakin' rogue angel." Soon the plane rumbled down the runway and into the air.

"So how does this (y/n) know Bobby?" Dean asked nervously, gripping the arm rests.

"So apparently once Bobby went to check out a vampire nest in Montana, and (y/n) was there alone. She had already killed two of them by the time Bobby got there; and actually she lived with him for a couple of months." Sam explained, looking at the email he had printed out. "So when was that?" Dean asked, wiping his forehead. "Fourteen years ago, she was only ten." Sam said. He passed his brother the piece of paper, Dean read it out loud, " 'Hey, Sam. So listen, I found someone that had The Colt. I tried to hunt him down but found out he works for Crowley. The hunter didn't give Crowley The Colt, not yet. So maybe we can hunt together. As I always say, 'More hunters that don't stab you in the back, the better' I'll met you at the airport at 5 o'clock. P. S, that's 12 a.m EST.' " He handed Sam the paper.

"How come Bobby hasn't mentioned her before?" Sam shrugged and said, "Dunno. But Dad briefly mentioned it," he flipped to a page in their father's notebook, "he wrote 'Bobby found a hunter at a vampire nest.' That's it." Dean nodded then cringed when the airplane had turbulence. Sam continued to look through the small book. The nine hour flight went by quietly, except for the fact Dean kept pointing out the man with the fez. The brothers picked up their bags and departed the plane, they looked around the food court. Dean nudged his brother in the ribs then nodded to a woman with (h/c) hair. They put their bags over their shoulders and walked over to her. You looked at them as they approached.

"(Y/n)? It's me, Sam Winchester, this is my brother Dean."

"Hey there, hot stuff."

You punched his arm playfully. Your face lit up but sadness flashed through your eyes only for a moment, you shook their hands, "It's so good to meet you." They walked through the airport to a parking lot. You led them to a (favorite color) Impala. "Nice ride." Dean said, whispering 'shotgun' to his brother. You started your car saying, "Yeah, Bobby said I could have her if I could fix her up." Sam got into the back as Dean got in as well. They buckled as you pulled out of the airport. "When I stayed with Bobby he talked so much about you, the stupid things you did for each other, the monsters you killed... He's obviously proud of you two." You paused and made a left turn, "I tried to call him a few times but it sent me straight to voicemail and he said to call you guys. I mean, I know he can handle himself, but he's the only family I've got." Sam and Dean sighed and looked at each other. "Bobby died a few months ago." Sam said, "He got shot." You sighed as well and looked out the window, "I would've thought old Bobby Singer would've gone down a more memorable way." You turned right and parked the car and turned off the engine. They all got out of the car as you changed the subject by saying, "If you walk down the street for five block there's the famous 221b Baker Street." You said, walking up onto the sidewalk as Dean looked to the left, a few blocks away people stood in front of a building, then he looked back at his brother and whispered, "What's 221b Baker Street?"

"That's where Sherlock Holmes lived. You know, Sir Arthur Conan Doyle? The author of 'Sherlock Holmes' the greatest detective ever?" Sam explained as you opened the door, leading them upstairs as Sam shut the door behind them. They walked up the flight of stairs, you unlocked a door and held it open for the Winchesters. They looked up as they walked through a devil's trap painted on the ceiling, unfazed as they looked around the room. "You've got a nice apartment." Dean said, putting his bag on the tan couch, "Actually, in the UK they call it a 'flat'." You corrected him, closing the door and heading to the kitchen.

"Had to learn a lot of stuff when I came here."

Sam looked at the bookshelves, "When was that?" He asked.

"About two years ago. Decided to get a change of scenery, also wanted to check out the Loch Ness monster." "Got anywhere on that?" Dean asked, laughing. "So far I've heard that there's a necromancer demon that want's to bring back the dinosaurs... But that's just a rumor." You said, passing Dean and Sam beers. "Thanks." You walked into your bedroom and came back with a box, "I got your stuff a few days ago." You said, setting it down in front of Sam and Dean, "What do you mean 'your stuff'?" "I sent our weapons ahead." "Without asking me?" Dean said, looking at his brother. "Dean, do you think we'd be allowed on a plane with guns?" Sam said, pulling out a few things and a pure silver knife and a bottle of holy water, "I just need to..." "Oh, yeah, yeah. Can't be too careful these days." You say, holding out your left arm. You didn't wince as Sam cut your arm with the knife, then he poured the holy water on you, proving that you weren't a Skinwalker or a demon. After that he pulled out a bottle of borax and poured that on your arm; not a Leviathan. "So why about The Colt?" He questioned, sitting down next to his brother. You sat down in a chair next to the dinner table, "I tracked the hunter for a few days, he took me to the Shell Building—" "Shell Building?" Dean repeated. You nodded, "Yeah, it's one of the office centers for the Shell oil company. Anyway, it's by the London Eye— that's the Ferris wheel on the Thames. I'm assuming they have a secret lair there. And of course I've seen Crowley around a few places, random places." "How random?" Sam asked, "Home Depot, Walmart, home improvement stores basically." Dean nodded and stood, picking up his bag, "Thank's for the tips and beer, but we should go on and check that out." You stood as well, grabbing a gun from the table. "Whoa, whoa, whoa, where do you think you're going?" Dean asked, holding up a hand. "I'm going with you." "I don't think that's a good idea." Sam said, putting his bag over a shoulder, "Listen, I found out where Crowley is, I found out where The Colt is. I'm going." You stated. Sam was about to say something but you were already out the door. "Hurry up ladies!" You called out. Sam and Dean looked at each other and shrugged, then followed you down the stairs and into your car. It was a short drive from your flat to the London Eye. You parked the car at the end of the block and pointed at a tall building, "There. I haven't been inside before, but once I spot the hunter I'll trail him." You said, getting out of the car and adjusting your jacket. "Oh, here." Sam reached out the window, passing you a Bluetooth earpiece. You put it in and fixed your hair.

"Once you're in you get The Colt. Don't do anything else. You go in, you come out. You got that?" Dean said, looking sternly at you. You looked at him and Sam,

"I'm a hunter, Dean. I've been practically on my own my entire life. At least you two had Bobby for most of yours. I'll be fine, Crowley's never seen me before. I've done my research."

Then you crossed the street and entered a door on the side of the building. "Ok, I'm in." "Good. Let us know when you have The Colt." Dean said, then looked at his brother, "I don't think this is a good idea." "Those are Crowley's men in there. No doubt they know what we look like." Sam said, holding his phone to his forehead. They sat in the car quietly, waiting for a response. Dean eventually hit the dashboard in frustration with his fist. "Sam, Dean." Your voice seemed shallow. Then someone knocked on the window. The Winchesters turned and saw a man. He smiled as his eyes turned black. "Hello Winchesters." Two demons ripped the doors off and dragged the brothers out, Sam and Dean fought the demons; throwing fists and trying to reach for the holy water. But Crowley's men overcame the Winchesters. Dean cursed as a demon held his arms behind his back while another put a gag in his mouth an a blindfold over his eyes before doing the same to Sam. the demons shoved Sam and Dean into the building, making a few turns and walked down a flight of stairs, leading into a large basement. Two more demons shoved Sam and Dean into chairs, handcuffing them down with thick pieces of leather then took the blindfolds and gags off before disappearing. "(Y/n)?" Sam shouted. "Ow, you shouted in my ear." You said next to him, your backs were all facing each other. "What the hell happened?" Dean asked, trying to look behind himself. "The Winchesters. Long time, blah, blah, blah." Crowley said, appearing in front of Sam. He looked at you, your jacket was thrown off to the side and you had long, deep cuts on your arms and legs; Sam then looked at Crowley, "What did you do to her?" The King of Hell smiled, "I didn't know the thee of you were so peachy." "What do you mean?" Dean asked, still struggling to turn around. Crowley stepped closer to you an sniffed your hair then said, "I thought you would have smelled her a mile away." "Shut up, Crowley!" You shouted. Crowley smiled, "I'm amazed you hid among hunters and they didn't even notice." "What does he mean, (y/n)?" Dean asked at the same time you said, "I will kill you, Crowley! I swear! I wont stop until your bones are salted and burned!" The King of Hell pretended to be wounded, "This one bites." He stepped in between Dean and Sam, "Do Moose and Squirrel know what you are?" Sam turned to face you, " 'What you are'?" He repeated, "What does he mean?" Crowley smiled then punched Dean in the face. "They don't know anything, Crowley!" Then he punched Sam, "Crowley, they don't know anything, I swear." The King of Hell took out a dagger and turned it in his hands then traced the tip on Sam's face.

"Fine! Fine, I'll give you what you want." Then you looked up smiling and said, "For The Colt." Crowley took the dagger away from Sam's face and slowly paced, "I think I would need something much more for The Colt." "Fine," you said through gritted teeth, "my soul." "No!" Dean snapped, "Crowley, what do you want her for?" "She has... information I need." Crowley purred, patting your head. Then he stood up straight then followed your gaze to the sweater. He walked over and picked it up. "This?" He asked, feeling inside the pockets, then pulled out a small beige button, a lot like the one's they have in Target. "Oh, now, what's this?" Your eyes widened, "Crowley, don't press that." Crowley smiled, then holding the button in the air, he pressed it. Then suddenly a loud noise pierced the air and Crowley's demons left their meatsuits. There was a strong gust of wind as the noise got louder and softer, getting louder and softer until a blue police call box stood in the middle of the room. "What the hell?!" Dean said, trying to comprehend. The door opened and you lowered your head. A man with floppy brown hair leaned out and said, "(Y/n)?"

So. How'd you like that? I'm thinking about continuing but this will definitely NOT be a one-shot.

Hope you enjoyed, ~ClevaChloe
