*as everyone has different things they like and dislike about the characters, I can't exactly write anything that you for sure like. But I've taken the liberty in trying; these are based off your personality I gave you for each preference and what you'd probably like*
S Holmes
His Majesticness
Why: come on, he's majestic like a dragon, admit it. Everyone wishes they had his level of smoothness.
J Watson
His Practicalness
Why: you figure it might have something to do with being roommates with Sherlock, but John's pretty practical, so that makes for some rather funny moments when both men are in the same room.
G Lestrade
Him
Why: he's just....the DI you have to like. There's literally no reason not to like him.
M Holmes
His Sophisticated Burning
Why: it's rare, but when he roasts someone while acting all upper class and important that perhaps makes your day.
J Moriarty
His Mysteriousness
Why: it's about as close you can get to a real book life, but falling for the mysterious guy and getting in cahoots with him sounds like a good story you'd never be able to read.
