Can you imagine a young Sherlock Holmes running around with an eye patch and a toy sword and he keeps jumping on the sofa (his pirate ship) and trying to tackle Mycroft (his hostage from an enemy ship) and while his parents think it’s cute that he’s having fun his energy levels are getting problematic so they buy him books on pirates where he learns about telescopes and so his parents buy him one (if he promises to behave) and he eventually starts to use it to be observant and look closely at things. He builds up a catalogue in his head of little things he notices and his pirate books become more history and science and then computing and as he reaches late teens he starts reading criminal psychology and solving cases and even though he’s an adult he still has his first little telescope in a neat wooden box somewhere In his old room in his parents house.
Being Sherlock and Mycroft’s Little Sister Would Involve
Requested by anon
Petty arguments with Sherlock about “trivial things” as Mycroft says but as soon as Mycroft tells you two to “Stop acting like children” you and Sherlock would turn on him. You imitating Mycroft, Sherlock with a quick comeback.
You’d be as smart as Sherlock but a little more absent minded. Sometimes you’d notice things that he wouldn’t but wouldn’t mention it because Sherlock probably already noticed and you’d just annoy him. Sherlock would soon realise you noticed different things so would start asking you.
They would both be very protective older brothers. Mycroft would be exhausted worrying about you both but he would know that if you and Sherlock went missing together you’d be fine.
Buying Sherlock Pirate themed birthday gifts every year. He raises an eyebrow at you but can’t help smiling when no one’s looking.
Buying Mycroft a keychain with an umbrella on it.
Often showing up to wherever Mycroft or Sherlock are because you’re “bored” and “need supervision, don’t I brother mine?”
Moriarty would get an interest in you. At first only to get to Sherlock but he quickly realises you’re quite interesting yourself. You’d tease him, mainly just to annoy Sherlock and Mycroft. Mycroft would “forbid” you from seeing him but you’d just laugh, knowing that wouldn’t work.
Sherlock calling you once to ask you for advice with Jeanine or Irene. He hung up because you wouldn’t stop laughing for three whole minutes. “Are you quite finished?” ‘Yes, sorry I just-” You burst into laughter again and Sherlock gives up.
When you were younger you’d be trying constantly to get their attention. You’d have learnt what interests them and would use this to your advantage. When you were in your teens, you would put yourself in slightly dangerous situations to get their attention. This would annoy Mycroft but amuse Sherlock.
They’d call you to settle their arguments. You’d flip a coin and give them a quick answer when you were preoccupied.
Teasing them, and receiving the same in return.
Learning to fight with a normal umbrella (without the sword) just to annoy Mycroft. He thinks it’s quite impressive.
John would at first think you were Sherlock’s girlfriend, or Mrs Hudson’s grand daughter. You’d think this was hilarious but Sherlock would just roll his eyes and carry on with the previous topic.
Sherlock worrying about you when you call him to say you’re bored. He picks you up and takes you on a case, knowing what you tend to do when you get bored.
Lestrade would be impressed by you. He’d quite enjoy talking to you.
Even though Sherlock and Mycroft could be arrogant, petty and overprotective, you’d love them, and would be sure to remind them of this constantly (if only to make them uncomfortable).
MYCROFT: My brother has the brain of a scientist or a philosopher and yet he elects to be a detective. What might we deduce about his heart? JOHN: I don’t know. MYCROFT: Neither do I. But initially, he wanted to be a pirate.
