/takes deep breath
alright, here it is:
it takes place in something like an AU, where it's separated from what happens in the shows but isn't? if that makes any sense. so like, john and sherlock still live together, except sherlock never jumped, john is still master of unstable relationships, mrs. hudson's still a bamf, and moriarty still toys with the baker street boys, always keepin' them on their toes.
cue in OC, who moves in across the street (it'd be a girl becuase +70 awkward tension and badassery) and somehow bumps into the blogger and consulting detective. they get chatting, and she somehow gets pulled into their latest case. she proves to be useful and adds to their little ragtag network of justice bringers, so they stay in touch and she regularly goes to solve crimes with them.
now there can either a.) be romance with OC x John or OC x Sherlock, or b.) they can stay as a super-awesome-triforce of epic bromance. whichever one you guys would prefer. but for option b.) there would be some major misunderstandings and miscommunication. like when they go to the morgue and lab and stuff, molly would start acting jealous because she sees another girl hanging around with sherlock, and john and sherlock pick up on this, and they start thinking, but all thoughts are private to themselves. John also gets a bit jealous, because he thinks the OC likes sherlock, so he starts trying to impress her by being all doctor-y and soldier-like and just all-around cute. meanwhile, sherlock thinks OC's pining on him as well, and it makes him feel out of his element because he's used to women being painfully obvious they like him, and OC still stays her normal, awesome self, so interactions between the detective and her start getting weird, because sherlock's trying to be nice and maybe even flirt and he just starts to loose his normal charisma and cold smoothness, and it interferes with his work and he can't think as quickly and easily as before. OC notices the two of them acting weird but figures it's just them and they have some government-ish stuff on their minds and she's cool with it. but then john makes an entry on his blog that somewhat hints at the fact that he believes OC is falling haha wow bad pun is bad. irony for sherlock, and even though he doesn't read his blog that often, sherlock sees the entry. so one night when she isn't there, john and sherlock have a little spat of sorts about "oh she's totally into you and it's pissing me off" and "you're mad? what about me? i can't even think properly and it's just ruining everything and i knew it was a bad idea bringing her into this" and mrs hudson comes down because "what's all that racket? oh i have tea and biscuits too" and she gives sherlock advice "you should just talk to her when you have the time", and so the next time sherlock and OC are in 221B alone together, he springs it up in an awkwardly straight-forward manner. "i know you like me. i mean it's pretty obvious [insert deductions that would look like proof that she liked him]" and OC is all astonished and shocked that he would even think that, but also finds it hilarious, so they both straighten the whole thing out and sherlock talks to john and everything seems all good because if they hadn't thought that she was hitting on sherlock than they wouldn't have started acting weird because they were both more than happy to stay just friends. but then OC becomes practically emotionless around them, like she'll hardly even smile around them, because she doesn't want to have another misunderstanding like that again because she's afraid someone will get hurt because of it, and john and sherlock don't know how to help her.
but then, moriarty keeps an eye on them the whole time and finds out how much OC means to the two men, so he starts hiring trained assassins and hitmen to kill OC, but he doesn't allow them to use firearms or weapons of any sort because it's "too kind and too boring". OC gets attacked by a hitman on the street, and just escapes to 221B all bruised and banged up. sherlock and john are super worried and they take care of her, but sherlock gets suspicious, so OC explains what happened to him, and he does what he's best at and finds this guy and who he is. he wants to perform a small experiment, so after OC heals, he has her walk down the street, him and john following a ways behind so it looks like they aren't together. another assassin tries to attack OC, but john and sherlock take him down and lestrade and crew show up to arrest him. sherlock explains that he thinks someone's after OC, but he doesn't know why. lestrade offers setting up guards around OC's flat and having someone always keeping an eye on her, but the three of them assure lestrade that it's not necessary. so since sherlock and john can't always be with OC and there always won't be someone there to help her, sherlock and john teach her how to fight. since sherlock's deduced that these hitmen don't use firearms or anything of the sort, their best option is teaching OC hand-to-hand and melee combat. they start training in this abandoned warehouse don't know why that exact place just go with it, and while john teaches her how to wrap her hands and wrists in handwraps so she doesn't break anything, and different military techniques and where to hit on a person to cause maximum damage or to stun/immobilize them. sherlock teaches her what to do in completely different scenarios and what to if this goes wrong or if this happens, etc. and over the course of their training, OC opens up again to the two of them, and when they see her smile again for the first time in a while, everyone's happy.
