Author's Note
Hey guys! This is my first fan fic, so I apologise if it's a bit slow/dull. Anyway, this is SebastianXMoriarty, and is set slightly prior to the BBC Sherlock canon: the events in the fic lead up to the tv show.
Later on in the story, there is a lullaby sang. I take no credit for writing it! Although I may have changed some words, all credit goes to (http://www.lullaby-link.com/child-of-moonlight.html) where I got the lullaby from.
Although Sebastian Moran is not mentioned in the tv show, he is in the Conan Doyle works, and is described by Holmes as The Second Most Dangerous Man in Britain. Many imagine him to look a lot like Fassbender, although in this fic he is closer in appearance to Matt Bomer.
It'll probably have a few triggers in it, so just be warned! Anyway, enjoy!

Sebastian Moran had been, and always would be, the one who mattered. To James Moriarty, he was a drug, an antidepressant, his sunshine on a rainy day.
On the day that they'd met, Jim had thought nothing of the tall, slender blonde, aside from the obvious fact that he was incredibly handsome and intelligent, in his own right. He didn't have the cold logic and reasoning of Sherlock Holmes or Jim Moriarty, no. But he had more intelligence than most, and the mental and emotional stability that Holmes and Moriarty lacked. Furthermore, he was an excellent strategist. He'd noted the dog tags that hung around his neck and, later, confirmed they belonged to Sebastian.
Within a few weeks, Sebastian had moved into Jim's large London flat, somewhat reluctantly. He was a professional man, and assumed that moving in with Jim would be 'unprofessional'. However, after some gentle persuasion consisting of a considerable increase in Sebastian's paycheck, he seemed to become more comfortable with the arrangement.

"Sebby!" Jim called in a sing-song voice, bursting into the kitchen, with a cupcake in his hand, a grin plastered across his face. Sebastian's emerald eyes flicked up from his newspaper, frowning at the eccentric madman with a bemused look on his handsome features. "It's our six month anniversary Sebby!" Jim grinned and gave him the cupcake.
"What?" Sebastian frowned, though he couldn't help but chuckle at Jim. He was mental, this man. But it was somewhat refreshing, a contrast to the harsh, stern faces he'd been stuck with in Afghanistan.
Jim giggled, "It's been six months since you moved in, silly! I even got you a personalized cupcake!" He clapped his hands excitedly. The cupcake was orange with black stripes, with bits of icing cut to look like the facial features of a tiger.
To his credit, Sebastian managed not to blanch at the sight of the cake. He wasn't exactly anorexic, but couldn't stand high-fat, high-sugar, high-calorie food. It made him sick. Even the smell of the cake made him feel queasy. But he couldn't say that to Jim: he'd gone through all that trouble to make Sebastian happy. To turn it down would just be wrong. So he smiled, "Thank you, Jim. I didn't know we were celebrating this though..." He murmured, guilty for not buying Jim anything.
At this, Jim hugged him tightly, "By just being here you've made it all better, Sebby! Look," He rolled up his sleeves. No fresh cuts. Just old scars. "Six months clean, thanks to my Tiger." He sat in a chair next to Sebastian, watching him eat the cupcake, smiling. Sebastian ate about half, then gave the other half to Jim, who happily ate it. He was glad to see Sebastian at least attempt to eat the cupcake.
Another few months passed, uneventfully. Jim would often wake to Sebastian making breakfast while listening to the Bee Gees, in particular, Stayin' Alive. Jim would laugh and dance around the kitchen while Sebastian cooked a full English breakfast for them both. Sometimes he'd forget his stiff upper lip and dance with Jim, laughing along with him, singing softly.
