IMAGINE: Solving a case with Sherlock and the Winchesters

    You sit on Sherlock's couch, shuddering uncontrollably. Sam Winchester settles a blanket around your shoulders. "What are you doing?" Sherlock asks him. "I'm-I'm giving her a blanket...?" Sam replies. "I can see that." Sherlock snaps sarcastically. "Then what's the problem?" "That's my blanket. I only use it. Go get her John's in the basket over there." Sherlock says, nodding to the corner. "Are you serious..." Sam mumbles under his breath, going to get John's blanket. "Dean, what are you doing in there?" Sherlock asks Dean who's in the kitchen. "Making Y/N some tea...? Aren't you guys famous for tea? Where is all of it?" Dean says, going through all the cabinets. Sherlock jumps to his feet. "Stop!Stop ransacking everything, my gosh! Mrs. Hudson will get us tea!" He exclaims. He opens the door. "Mrs. Hudson! Mrs. Hudson!" He shouts. "Guys, stop! Just stop!" You cry, breaking your silence and looking at them. All three of your best friends look at you. Tears fill your eyes. "Please." You plead. "One of my friends was just mauled in the middle of a forest. I need some peace and quiet." You state, your voice cracking. You are best friends Sam, Dean, and Sherlock. You decided to travel to England to visit Sherlock for a couple of weeks. You brought the Winchesters and your friend Celia from work. On the fourth day of your journey, you found Celia mysteriously dead in the woods. "I'm sorry, Y/N." Sam says, sitting beside you and rubbing your back. "We're all sorry." Dean states, walking over to you. "I'll find who killed Celia, Y/N. I promise I'll find who it is." Sherlock vows. "We will all help find who killed her." Dean fires at Sherlock, glaring at him. Sam puts his arm around you protectively. You sigh and rub your forehead. Why you ever thought bringing the Winchesters to England was a good idea is beyond you. Back home you helped the Winchester brothers with demon hunting, and they both fell in love with you. The tension was enough without having to add Sherlock into the mix, who, as well, is in love with you. --- That night you sit on the steps of Sherlock's building, your legs up to your chest. You stare at the pavement, your eyes flooded with tears. "Hey." Sherlock says softly, sitting beside you. "Hey." You whisper. You look at him as he gazes at you sympathetically. "Where are Dean and Sam?" You ask hoarsely. "They're upstairs, arguing over...you." He states. You wince. "How come you didn't tell me they're in love with you?" "How did you know they're in love with me?" You ask in surprise. You sigh deeply and shake your head. "You know what, that is a stupid question." You laugh softly. Sherlock smiles at you. "I feel so stupid for bringing them here, Sherlock—knowing how the three of you all feel about me." You sigh. "Not to mention feeling guilty for inviting Celia to come along. If I hadn't, she'd still be alive." "Y/N, you can't feel guilty about Celia. It's not your fault. It could have happened to anyone. You can't change what you can't stop. You can't live your life wondering what would have happened to Celia if you hadn't invited her to come. It was her choice to come. You can't feel guilty about what you can't change anymore." You nod. "I know." You whisper. Sherlock wraps his arm around your shoulders and pulls you to his side. "And Y/N?" He asks. You look at him, your eyebrows raised. "You have three men vying for your heart, but I'm going to be victor." He whispers. You laugh softly. --- The next morning Sherlock, Dean, Sam, and you go to the forest where you found Celia's mauled body. All of the memories of her bloodied body come rushing at you and you feel sick. "Are you okay?" Dean asks, touching your arm. You shake your head. "Come here." He murmurs, pulling you into his arms. You feel Sam's and Sherlock's eyes burning into your back. "We're going to get through this, Y/N. I promise you we will. I will be by your side through it all." Dean whispers. "I know you will." You whisper. Sam clears his throat and Dean and you break apart. "I saw what Celia's body looked like in the morgue. It was pretty ravaged. It almost looked like a wild animal tore her to pieces." Sam states. "No, it wasn't an animal. Her body was ravaged but the marks on her body were made by no animal." Sherlock protests. "How do you know?" Sam asks. "Trust him, Sam, he knows what he's doing." You state. Sherlock smiles at you. "So definitely a person did this." Dean says. "But why? She was only in England for a few days. Nobody knew her. The murderer must have seen her while we were all out walking the nature trail. He then waited for her to be by herself so he could get her alone. He was targeting her." You murmur. "Wait." Sherlock whispers. He looks at Sam and Dean. "You know a lot about demons, right?" Dean scoffs. "Um, yeah." "Wait, you're not suggesting a demon killed her, are you?" You ask. "I mean, it's kind of far out there, but we shouldn't dismiss the idea." Sam admits. Dean sighs. "I guess we could look into it." You smile. "Good work, Sherlock." You say. He grins proudly. --- A couple of days later Sam and you are at Sherlock's house while Dean and Sherlock are at the morgue talking with Molly Hooper about Celia's body. "Sam, how big of a chance do you think it is that a demon killed Celia?" You ask, watching him as he's on his laptop. He doesn't answer you. "Sam?" You ask. Still no answer. "Sam!" You exclaim, hitting the table. "What! What!" He exclaims, jolting back. He looks at you his eyes wide. "What is it?" "What just happened?" He blinks and shakes his head. "I'm sorry, I was just-I was just..." He sighs and rubs his head. "The more I think about it, the more I believe Celia was killed by a demon. All the signs are adding up and, honestly, at the moment, it's the only thing that really makes sense." "I was scared it was going to come to this." "I think in the next couple of nights, we should do a stakeout where Celia was killed. That way we can just see if there's any suspicious activity going on." Sam suggests. "I agree. Let's talk it over with Dean and Sherlock when they get back." You say. You bite your lip. "Are you doing okay, Y/N?" Sam asks. "I don't know." You admit. He reaches his hand across the table and covers it over yours. "We will find this demon and we will kill it." He whispers. You nod. --- "This is stupid, the demon is never going to be here." Sherlock grumbles. "Please, Sherlock, we need a little optimism right now." You say. Sam, Dean, Sherlock, and you are all crouched in the bushes near the spot where Celia was killed. It's completely dark outside. "He obviously has no patience." Dean points out. "Hey-" Sherlock starts to say. "Guys, please no fighting!" You hiss. "Sorry, Y/N." Dean apologizes. "Hey, look!" Sam whispers, pointing as you see a figure moving through the trees. "Stay alert." You whisper. The Winchesters' hands go to their weapons at their sides. The figure is dressed in black and is limping. You narrow your eyes as your hair stands on end. "This is the person. This is the demon who killed Celia. I can feel it." You breathe. "Dean and I got him. Sherlock, stay back with Y/N." Sam commands, before Dean and he run out of the forest. Sherlock pulls you into his arms and adverts your head from Sam and Dean. You bury your face in his shoulder. You hear Dean and Sam shouting. Then a gun shot. You jump and Sherlock holds you tighter. Then there's another gunshot. After that, there's absolute silence. "Is it over?" You whisper. "Yes." Sherlock breathes as Dean and Sam come running back to you. "He's dead. He openly admitted that he killed her. Just for fun." Dean states. You turn around and look at them. "Oh, Celia." You whisper. You sink against Sherlock, weeping. --- You lay on the couch at Sherlock's, relieved that this whole ordeal is over with. "Guys, I can't thank you enough. All your hard work and dedication helped lead us to the killer." You say to Dean, Sam, and Sherlock. You sit up and look at the three of them. "Of course, Y/N. We told you we were going to find out who killed her." Dean says. You smile. "I know. And you did, and I can't be more grateful." You reply. "You all mean so much to me and I don't know what I'd do without you. You're all my best friends." "But?" Sam asks. Your eyebrows draw. "But what?" You question. "Come on, Y/N. We all know we are all in love with you." He states. "Sheesh, nice way to point out the elephant in the room." Dean mutters. "Well, he's not wrong." Sherlock says to Dean. Dean shrugs. "So who do you choose? You've had enough time to figure out which one of us you're in love with." Sam says. You stand up and start to pace. "You're right, that's very true." You murmur. Sherlock, Dean, and Sam all lean forward in their seats, eager to hear what you have to say. You wince. "See, the thing is...I'm not in love with any of you." You state as a whirring noise starts to sound. "What!" Sherlock exclaims as there's a sudden gust of wind. "What do you mean?!" Dean exclaims in horror. "I'm so confused!" Sam cries. "If you're not in love with one of us, then who are you in love with?" Sherlock practically shouts at you to be heard over the loud noise. Your hair blows all around you and you smile widely as a blue box lands in the corner of Sherlock's living room. The door creaks open and then the 11th Doctor pokes his head out. "Y/N, I believe it's time to go." He states, smiling. "Oh, hello, everyone!" He exclaims, noticing the Winchesters and Sherlock staring at him in shock. You back away towards the Tardis, grinning uncontrollably. "Geronimo." You say, before walking into the Tardis. [THE END] I hope you liked it!
