Chapter Text
Lestrade considered himself to be a smart man, after all not just anyone can become a detective inspector. But the tall genius liked to remind him daily how boring and mundane he actually is.
He had known Sherlock for just over three years, and in that time he saw all different sides of him. When they met, it was the young genius sauntering onto the crime scene high as a kite solving the gruesome murder. He told him off and yelled at him to get help or he would be arrested for breaking and entering. A few months later he had gotten a text from some random number letting him know he was in rehab, getting help and letting him on the next time he came around. It started as a reluctant partnership, but Greg grew to enjoy helping the young man out, even if he pissed off half his team in the process.
He didn't know much about Sherlock, no one did. He was an untouchable aura of power and wits, and he had seen his fair share of you'd constables try and flirt only to be ripped apart by his spot-on sections. It's not that he didn't try because he always did, it's that Sherlock kept up all his walls and never let anyone in enough to see the real him.
That's why today of all days, he had no idea his entire perception of Sherlock was going to change. As he was standing inside the crime scene, he heard a commotion outside that told him the consulting detective was finally in. He knew his appearance always caused a stir for Donovan, but when the cases were unsolvable he was all they had. When Sherlock finally entered the flat, what surprised him the most is that he was not alone.
"You need to wear one of these" Sherlock said while motioning to his (friend? colleague? homeless network?) partner to grad a blue suit.
"Who is this" Greg nodded his head towards the shorter man.
Sherlock didn't look up from putting on his gloves, just replied with his blank tone "He is with me,"
"But who is he?!" Greg pushed forward, wanting answers for once.
"I said he's with me" Sherlock finally looked up and snarled at the detective inspector.
"Sherlock" the shorter man gave him a pointed look, and for once in his life, the detective actually listened. Lestrade couldn't believe what he was seeing and couldn't help but wonder who this short miracle of a man was.
The short man turned to Lestrade, and offered a hand "the name is John Watson, nice to finally meet you, detective". Lestrade wasn't a master of deduction, but he was smart enough to know John most know Sherlock will enough to feel comfortable joining him at a crime scene and gave him an understanding smile while sharing his hand. So friends then?
"Aren't you going to put one on?" John asked Sherlock, who looked gave him a look of pure annoyance. Most people cower under his gaze, but this John simply laughed.
"So where are we" Sherlock looked expectantly to Lestrade.
"Upstairs" Greg replied reluctantly. He was already breaking every rule letting him in here, what was one other psychopath.
