Rating: PG-13 (offscreen violence, implied torture)
Summary: Sherlock has been injured. Mycroft is irritated that the criminals of London keep forgetting that Sherlock is his brother.
A/N: First Sherlock fic. Did it work?
The thing that people- notably, the criminals of London- don’t seem to understand is that, underneath it all, is that Sherlock Holmes has an older brother. It’s a large age difference- seven years is nothing to sneer at- but Mycroft’s little brother has, is, and always will be...important. To be protected. An older sibling is in a unique position. They are not an adult- their brother will admit things they will hide from their parents. They are older- their parents will trust them to look after their younger brother. They are trusted, even when they are hated.
And Mycroft knows that Sherlock hates him. Oh yes, it is a hatred that spans the ages, and Sherlock will never, ever, ever forgive him.
For what, exactly, is unclear to Mycroft- being right? Knowing more than him? It has never been explained, and despite Mycroft’s frankly intimidating intellect, he is just as bad with people as Sherlock is.
No matter. Sherlock has decided they are enemies, that he will not call on Mycroft for anything.
Except when something happens that truly damages him.
Then, Sherlock Holmes, consulting detective and London’s leading high-functioning sociopath, turns back into Sherlock Holmes, age five, who has just fallen over and hurt his knee doing something Mummy said he shouldn’t, who goes to his brother for help. Or, alternatively, Mycroft Holmes, MI5, MI6, CIA and the entirety of the British Government, turns back into Mycroft Holmes, age twelve, who is armed with band-aids, determination, and the knowledge that Sherlock just wants a hug.
Admittedly, Mycroft gets protective a lot more easily than Sherlock gets damaged.
It’s happened again, actually.
Mycroft is sitting next to Sherlock’s hospital bed, eyes caught on the oxygen canula under Sherlock’s nose. He knows, logically, that there is nothing he could have done to stop Sherlock from getting injured. He is a supremely pig headed man, and little short of tying him to a chair would have stopped him from pursuing the lead that had taken him to the docks. Still, despite this logical knowledge, Mycroft knows that he has failed. Mycroft Holmes is an older brother- he is supposed to look after his younger brother. Next time, he shall tie Sherlock to a chair.
In another ten minutes, the anaesthesia will wear off and Sherlock will wake up.
Mycroft will be long gone by then.
He has a man to find.
A man who thought it would be a good idea to break Sherlock’s fingers.
Mycroft’s relationship with his brother has changed over the years, gone from comforting hugs to biting sarcasm to distant supervision. He can discard his outside when Sherlock grows out of the need for a brother who nurses his hurts, or a brother who can hold up his side of an argument, or a brother who can manipulate CCTV and kidnaps prospective flatmates.
But at the root of it all is Mycroft Holmes, older brother. And when he sees his little brother lying in a hospital bed, he knows exactly what is going to happen to whoever put him there.
He has a list.
