John's POV
The last day of the full moon goes rather normally, even though they stay home. So he is thrilled that that he feels as good as he does because they end up getting a call for help from Greg who has a double murder and missing child to deal with and wants them to look for the child. After fourteen crazy hours of running around London, they find the little boy in a cage in warehouse, his clothes shredded and tears running down his face as he whimpers silently.
Frowning, he has Sherlock pick the locks on the cage before he carefully picks the little boy out and smells his wolf scent as soon as he does so. This child is a werewolf. Probably a born one since he cannot see any bite marks on him. After using his phone to summon Greg, he hands the little boy to his vampire before pulling his gun and stalking through the building. Someone just entered according to his heightened senses and with malice in their plan. What he finds is a pair of humans with guns talking viciously as they head through the building to where the little boy was caged at. Not that they make it. He puts a bullet in both their heads, thankful Mycroft had registered his weapon after he saved Sherlock's life with it the first night they knew each other.
"From what I have found there is no one who can take him," the copper says after the force gets there.
"We'll keep him," he remarks, taking the child back from his flatmate and encouraging him to lay his head on his shoulder.
Hesitantly, the older man looks between the two of us, before remarking, "Are you sure that is a good idea?"
"If John says we're keeping him until his family is found, then we are keeping him." The dark-haired vampire replies seriously, grabbing his phone and quickly texting his brother about what he needs.
Less than five minutes later the sleek black car is pulling up, the older vampire glancing between them before having a silent conversation with his brother that ends with a nod.
"Use my car," the auburn-haired man offers.
Now it's his turn to have a silent conversation with the boffin before nodding to the politician and heading over there, child still firmly wrapped in his grasp.
The ride to the flat is quiet with the brother's sharing a silent conversation while he merely cuddles with the little boy. He could probably walk, but he would rather him not until he can replace his clothing and shoes.
"Anthea will be by in an hour with supplies," the politician remarks when they get out.
Nodding, he replies, "Thanks Mycroft," before heading inside with the little boy. Once in the flat he sits him carefully on his chair, before kneeling in front of the child and stating, "My name is John, what's yours?"
For a long time the child says nothing, just stares at him. Eventually he mutters, "Kyle."
"Besides your parents, did you have any other family? Maybe a pack?" he asks gently.
Tears well up as the little boy shakes his head. "Family gone. Pack gone. Hunters."
Hugging the child, he decides then and there to try and keep him, hopefully Sherlock will be willing to help, otherwise he will have to move out and that is not what he wants. "You can stay with me, if you want," he offers the little boy.
Nodding, the child clings to him, hiding his head in his neck as he sobs his heart out before drifting off to sleep in his arms. Carefully, he carries the little boy to his room, setting him down on the bed before fetching a warm wet flannel to wash him with and then tucking him into one of his old, soft tee-shirts before putting him under his blankets. Heading back downstairs, he discovers the two vampire brothers sitting silently together in the living room, fresh teas waiting for both.
"Are we keeping him?" the younger brother inquires, arching an eyebrow.
"If you're willing, yes," he replies.
Smiling, the younger man nods once, before turning to his brother, "Insure that Kyle's paperwork is all in order if you please." Despite the polite wording it is not a request.
A sardonic smile curves the older vampire's lips as he replies, "If you're sure, you know Mummy will expect a visit with this."
"Once our pup is adjusted we will be more than happy to visit with your mum," he replies before his vampire has a chance to say anything.
"As John says," the younger man agrees with a sarcastic chuckle.
"In that case, I must be off, paperwork to complete to avoid problems," the older vampire remarks as he stands, "John, Sherlock."
Walking the taller man to the door to the outside he murmurs, "Thank you," much to the politician's surprise according to his expression.
When he gets back upstairs he is surprised to see his vampire shifting from foot to foot, hands clasped together before him.
"Something wrong?" he queries lightly, moving towards him and happy that his injury has healed so well.
Shaking his head the younger man replies, "Nothing is wrong, this just moved my schedule up a bit."
"Schedule?" he repeats questioningly, particularly since he knows beside experiments, the younger man never schedules anything.
Thrusting one hand before him, the vampire inquires, "Will you marry me?" before flipping his hand upwards to reveal a plain silvery band that he is sure is platinum and not silver.
For a long minute his eyes stare between that band and his partner eyes before he grins and throws his arms around the taller man answering, "Of course!"
Smiling in relief, the younger man slips the ring on his hand before kissing him gently. The kiss is just beginning to deepen when a scream from upstairs has both of them turning and bolting to his room.
Instead of sitting on his bed like he expects the little boy to be, he is hiding between the closest and the dresser. His eyes are wide and wild as he looks around in terror.
"Kyle, shhh, its alright," he murmurs to the little boy while his mate stays by the door, "You're safe now."
Several minutes pass as he coaxes the child out of his hiding spot and into his arms. As soon as the little boy spots his mate however he goes back to hiding, staring in dread at the vampire.
"Give me or get me one of your worn shirts," he mutters, knowing the taller man will understand.
Nodding, his vampire quickly strips it off and hands it to him before retreating out of the room and down a few steps.
"Kyle, shhh, it's alright, I promise, this is my mate's scent. Any time you smell it, you'll be safe because he will protect you." he murmurs as he scoots closer to the little boys hiding spot, holding the shirt out.
"Vampire," the little wolf mutters as he shakes his head violently.
He smiles reassuringly at the little wolf, "He is a vampire. He is also my mate."
"But you're wolf, he's not," there is confusion in the boys tone.
Still smiling, he nods, "You're right, I am a wolf and he is not, but we are still mates. If you let us, we'll be your family and protect you always."
Biting his lip the little boy eventually takes the offered cloth to sniff a few times. He can see the fear in his eyes but he can also see that he is trying.
"Remember he held you for a little bit earlier, did you feel safe then?" he prompts softly.
Thoughtfully, the child looks between him and the cloth before nodding slowly.
"There you go," he murmurs, "Are you hungry? You look hungry."
"A little," the child answers shyly, scooting out a little and glancing about.
"Then how about we go downstairs and get some lovely roast? My vampire made it for me so I wouldn't have to worry about cooking between shifts." He suggests gently.
"Really?" the little boy questions, sounding very disbelieving.
He nods, "Really," and offers a hand.
After staring at him for several long minutes the hand is accepted and the boy with the shirt allows him to scoop him up before heading downstairs with him. In the living room he finds a waiting plate full of food cut into small pieces along with three forks. Over the next couple of hours, even through Anthea dropping off supplies, he holds the little boy and allows him to adjust. When Mycroft returns with the paperwork well after midnight, his vampire fetches it from him downstairs. Allowing the young boy to stay safely curled in his arms and adjusting to the scents of the house. That night the three of them curl up on his bed rather than his mates so that he can continue to feel safe and keep adjusting to their combined scents.
