Sebastian stared up at Sherlock - his elder brother - with frightened blue eyes, gripping onto his stuffed tiger toy tighter as his attention was drawn back to the three boys setting up the devil's trap and alter in front of them. Sherlock only rolled his eyes at the reaction hardly believing that boy at his side was a Holmes let alone his younger brother - Sherlock had originally planned on coming here alone tonight, well, that was until his parents abruptly ended that idea, when they announced that they would be going out on a date night (Oh! How very quaint? He thought at first), but due to Mycroft being at school it was his responsibility to care for his younger brother.

When the older boy's had prepared the traps and lit the candles, they pulled their hooded cloaks on and began chanting, causing Sebastian's small heart to beat five times as fast. A whimper escaped his lips causing Sherlock to grab him by the wrist with an impossibly tight grip and turn him around, the elder brother bent down and glared deep into Sebastian's eyes. "Shut up or else..." He snarled, his silver eyes filled with hatred and deceit.

However the moment was cut short as the air began to grow cold and dark smoke started seeping through the wooden floor boards, causing it to creak. Sebastian was in tears by then, falling to the floor in fear and gripping onto his tiger as though it would protect him. The small boy watched as a dark figure formed in the centre of the devil's trap, everything about it screaming 'danger' however none of the boys, except Sebastian were frightened.

A boy with dark ravenous hair that could almost match Sherlock's stepped into the trap, his chest having been painted on with blood, the smoke demon seemed to react to this gesture in kind, possessing the boy quickly, before laughing like it was insane. Sebastian at that point had no doubt that it was, everyone in this room was, but not him. The boy slowly started to back away nervously, pushing his way towards the door before a hand reached out and grabbed his shoulder, causing him to scream only to realise that it was Sherlock's. "And where do you think you're going?" His elder brother cooed before pulling him back towards the beast.

"I would like to make a deal..." Sherlock stated immediately, causing the demon to jump with artificial joy, his eyes dark as it crept forward, towards the inner edge of the devil's trap.

"Continue..." The demon mused in a deep Irish accent.

"I want to know everything there is to know about the universe and everything in it, call it scientific curiosity, because I want to know it all..." He paused. "I also want my ability of deduction to improve..."

The demon hummed in thought before pacing the cage thoughtfully. "And what do I get in return? Hmm...Such great things come at such a high price..." The demon sung in a malicious sort of way, before turning back to face him.

"My brother..." Sherlock stated bluntly and without hesitation causing Sebastian to jump and look up at his brother with fearful eyes.

"Sherlock. No!" The little boy sobbed, gripping onto his tiger and shaking as Sherlock barely looked at him more interested in the demons response.

"What's wrong with him?" The demon enquired, eyeing the boy suspiciously, trying to identify any problems.

"Nothing. He is perfectly healthy. He is just - He is just a nuisance I would much rather be rid of..." Sherlock mused looking down at the crying child briefly. "So...Do we have a deal?"

The demon eyed the boy cautiously, before turning his attention back to Sherlock and nodding, more concerned about the little boy then the elder brothers deal. "Yes. Of course. Now. Give me the child!" He demanded before edging closer as the other boys backed away.

Sebastian looked up at Sherlock shaking his head repeatedly and trying to stick himself to the ground only to fail, when the elder Holmes simply picked him up and dangled him in front of his face in a taunting manner. "You will behave little brother..." He scowled, glaring at the boy and taking the boys tiger the moment he put him down within the devil's trap. Sebastian started screaming immediately, tears staining his face as he glared up at his brother and attempted to escape from the demons grasp.

"Is that all you want from me, Holmes?" He enquired, his voice almost as taunting and shrilling as a viper attacking its prey.

"Yes. We are done..." Sherlock stated darkly before steeping forward and breaking the line of the trap, allowing the demon to escape with its new vessel and his little brother.

The trip to hell was excruciatingly painful for the mortal boy, his body having been ripped apart particle by particle before being reassembled outside of a rather large mansion - armed with living gargoyles and terrifying statues that moved every time you blinked. It was a terrifying place for a child to be. The demon rushed to Sebastian's side, checking the crying child over for any scarring ascertained from the trip before finally pulling away. "Follow..." The demon ordered, not bothering to look back at the sobbing child; even after that brief display of compassion.

Sebastian's stumbled up the paved drive, trembling as the statues grew closer and closer to him until the demon dismissed them - the boy was lead into the mansion and up the ever spiralling stair case to his temporary room. "W-What are you going to do to me?" He whimpered having not strength to fight back without the support of his tiger.

"Nothing...well...That's not entirely true" The beast mused. "I will raise you. I will teach you how to survive in this world and when you are old enough you will become my bodyguard..." He paused. "But - Make no mistake, Sebastian - I /Own/ You" His voice rumbled growing dark as he looked down at the boy with an amused expression enjoying the child's fear. "Now! Sebastian. Tell me - Why do you like that 'tiger' of yours so much?"

The little boy flinched away immediately, looking up at the beast with a nervous expression before regaining enough of his composure to reply. "Because it protects me and Tigers are awesome, but I'm not allowed to have a real one though..." The little boy pouted. "Myc says that their dangerous and shouldn't be kept as pets but I tried to argue that I didn't want one as a pet. I wanted one as a friend because I don't have any friends. Sherlock always scares them off..." He sighed looking down sadly. "Myc brought me Tiger so I could have a friend but now he is gone..." His voice faded away and he looked down with sad eyes, knowing that he couldn't go back anymore. He was the demon's property. It owned him and as long as that was true - He could never go back.

"Well..." The beast sighed pulling out Sebastian's tiger toy from the satchel behind his back. "Tiger can't protect you, because he is a toy..." He teased before lowering the toy to the ground. "But a real tiger can..." He smiled softly once again (It was a smile that he only reserved for the boy), and waved his hand over the toy as it jumped to life causing Sebastian's eyes to widened in surprise. The boy immediately leaped forward and carefully tackled the cub to the ground playfully, hugging it tightly and pressing soft kisses to its furry head. "Thank you. Thank you. Thank you..." Sebastian praised gleefully.

Sebastian was to busy playing with his new tiger to realise the demons absence, however, it wasn't every long before it returned with a few blankets and a softer pillow. "Extra supplies considering we now have another guest staying with us..." The beast mused with a cunning glint in his eyes as it sat down beside the pair. "Have you decided on a name for your new friend yet?" He hummed reaching out to stroke the furry creatures head only for it to growl at him for getting to close to Sebastian. The boy giggled at the shocked expression left on the beasts face before pulling his tiger into his lap and humming for it to settle - Which it did almost immediately.

"You shouldn't do that..." Sebastian commented, stroking the cubs fur before looking up at the demon with a dark and menacing expression, that seemed to contrast with his otherwise angelic features.

It took away the demons breath at first, realising that he had underestimated the small child, before composing himself enough to respond in a challenging tone. "Shouldn't I?" He chimed, his blackening eyes becoming soulless as he stared down at Sebastian.

"Fine, but don't blame me if he attacks you because it would be your own fault.." The child refuted obviously used to arguing with his older brothers. "It would be because of your own stupidity anyway, demon..." He teased letting out a small hiss at the end, glaring up at the beast once again before his face changed back to being angelic and sweet.

"Aren't you just troublesome and misleading...Tiger..." He hummed tauntingly, seeming to like the nickname for the small child, it suited Sebastian - one for his personality, but also because of his behaviour.

"T-Tiger?" The child furrowed his brow and scrunched up his face annoyed, turning his attention back to the demon. "I'm not a tiger and that name has already been taken..." He grumbled, gripping onto the living tiger in his arms tighter.

"You can't just call a tiger, Tiger, Sebastian..." The demon argued, receiving a withering glare from the boy in response.

"Why not? I call you demon and you're a demon..." He hissed making a fair argument, that seemed to render the demon speechless once again.

"Fair enough, but I haven't given you an actual name to call me by..." It stated in reply only to realised that it would be wise to actually give the boy his name in case he got lost and didn't know how to get back to the mansion without him.

"James Moriarty..." Sebastian murmured against the tigers furry head. "That's your name, I read it on the sign outside. I can read you know..." He growled, almost sounding annoyed that the demon hadn't figured it out already. "I just prefer to call you demon because that's what you are..."

Jim looked hurt, and oddly enough his chest began to ache. "Very well..." He sighed, pulling the two closer despite their best attempts to struggle out of his grip; the tiger pawing at him with relatively sharp claws. "What must I do for you to like me? Hmm..."

"Let me go home!" Sebastian cried, causing the tiger to growl at Jim for hurting the boy in such away.

"You know I can't let you do that. A deal is a deal and your brother gave you to me to secure his..." He stated bluntly, before reaching down and cupping the boys face. "Why would you want to go back to them anyway? Hmm..."

"Because they're family and family means nobody gets left behind..." He whispered softly as tears started falling from his silver eyes, causing Jim's heart to break wanting to do nothing more then hold the boy against his chest and hug him until the pain went away. "Or forgotten...but they left me behind..."
