"Adopted?" John asked, an eyebrow raised as he sipped his tea. He glanced up at Sherlock with warm brown eyes while the Detective only nodded. "I never pictured you being adopted. I thought you and Mycroft were like twins or something with the way you two go at it."
He shrugged, silver-blue eyes scanning over John as he made his deductions. "My parents never told me who my real birth family was, they just said they were American and had the last name 'Winchester'. Apparently their mother, my mother, killed in a fire or something along those lines."
"Rough." The Ex-Army Doctor said as he took another sip of his tea. "Did you ever look them up or anything?"
Sherlock blinked, going over the question once more in his mind before answering. "Yes, I did actually. Found about a thousand Winchesters in Kansas, the state I was born in apparently, the only Winchesters I found that my parents said were it was some guy named John Winchester, he's dead now."
John looked up at Sherlock but his best friend only wore an emotionless gaze. "Anyone else? He had a wife and didn't your parents say you were the youngest?"
"Sam and Dean." Said the Detective suddenly as he straightened up as the doorbell rang. "Dean died, pressed for murder charges and Sam...he's god knows where. I'll get that if you don't mind."
Sherlock bounced out of his chair and walked out of the room to answer the door. John's gaze followed his friend as he went, there hadn't been a case in weeks. It had been as if all crime had suddenly dropped off, an occasional robbery or even an accidental hit and run. A deep and raspy voice was heard through the open door but John couldn't make out what the man was saying. He finished off the last of his tea before standing just in time to see Sherlock walk in with a man in a tan trench coat at his heels.
"This is Castiel." Sherlock said, gesturing the man behind him as the man looked around at the flat. "Apparently he had something to tell us."
Castiel nodded, sapphire blue eyes boring through the both causing John to shiver at their hollowness but Sherlock only met them head on with an unaffected gaze. The man spoke slowly as he said "Sherlock, I understand that you're related to two people named Sam and Dean Winchester?"
When the Consulting Detective nodded the man picked up quickly. "Good because...this might sound a little strange because there's a; how do I put this in terms without you freaking out? Um, there's a demon going after you."
John raised an eyebrow in confusion but then Sherlock chuckled, a tone of disbelief in his voice as he laughed. "Now that is dumber than the 'mutant dog' as Baskerville! Do you really take me for an idiot? Or are you just taking the confusion route of saying 'Moriarty is alive' or whatnot?"
He narrowed his blue eyes in annoyance but then his head snapped up as an idea crossed into his mind. Castiel opened his mouth to say something but Sherlock cut him off. "Are you saying that Moriarty made a deal with the devil? You must take me for an idiot if you want me to believe this."
"I speak no lie." Castiel growled, John noticed him roll his shoulder as if he was adjusting wings on his shoulders. "You should believe me. Remember that murder in the newspapers a few weeks back? No marks on the body only a strange scent of sulfur? It was something...not human. You have to believe me."
The Consulting Detective rolled his eyes and groaned. "John hand me your gun because I think he's going to keep talking. And besides, if that victim had been killed by something 'not human', what did kill her then? And how would you know of this stuff anyway?"
The man gave a smile as he waved his hand, the blinds shutting themselves in an instant causing Sherlock and John to jump in surprise. Sherlock looked around the flat for any means of explanation but there was none...until he looked back at Castiel. The man stood tall and shoulders back but that wasn't the strangest thing. Through the filtered light that escaped through the blinds, two wings that seemed to made of pure shadow arched off of his back.
Sherlock blinked many times as if he was trying to blink away the illusion but the wings stayed. The Detective shook his head and whispered something under his breath. John didn't hear it but Castiel did. The shorter man's eyes began to glow as if their own light source until he was enveloped in a white light. John shielded his eyes from the light but Sherlock only stared on in horror. When the light vanished, Castiel waved his hand and the blinds opened allowing sunlight to enter the flat.
"What are you?" Sherlock said, voice low and threatening but under all that there was a hint of pure disbelief.
Castiel blinked, a smirk crossing his face as he said "Angel. I am Castiel."
John blinked, taking in the facts that were before his eyes a lot better than Sherlock, who was shaking his head in disbelief, pure and unaltered disbelief. "Okay, I can believe that you're an angel but how are you here? Did you fall or is that a form you can take?"
The angel blinked "Yes, I fell from the ranks of my kin but this is just a mere vessel I take control of. Stronger species, Angels or Demons, have the abilities to take a human vessel...kind of like possession as humans see it."
"You're controlling some poor bloke?!" John said, eyes widening in horror as he thought of the man beneath.
Castiel shook his head and sighed "No, he allowed me entrance. So calm down. There are things I ask of you two, well mostly Sherlock."
The Consulting Detective looked up through a narrowed gaze as he said "What? What would you possibly need of me?"
"Easy," The angel said through a chilled tone "you're kin to my friends and your brothers, Sam and Dean, and apparently other things are taking notice that there are three Winchesters not two. Things are taking interest in you, dark and terrible things."
Sherlock blinked "Then what am I supposed to do exactly? Run or fight?"
"Both," Castiel said as he took a step closer towards John, who, in return, took a step back from the approaching angel "I am taking you two to America. It's a lot easier and safer being most of the things going after you will imagine you two to be only in London."
The Ex-Army Doctor nodded as he crossed the room and opened the desk drawer that held his not-so-legal firearm. Castiel glanced at the weapon before continuing in his regular emotionless voice. "I can provide you movement to America and to the Winchesters but I cannot promise the safety of you two after you leave London. Are you still up for the journey?"
The Consulting Detective nodded, a smile crossing his face as his eyes glittered. "Of course! This is the funnest idea anyone has had in weeks here!"
The angel frowned, taking note of the Detective's want to see bloodshed. Sherlock would not be disappointed. He had already grabbed his coat and scarf while John was already dressed and ready to go. Sherlock slipped on his scarf and coat while Castiel only grabbed John's wrist and Sherlock's forearm.
"You may live to regret this." Castiel mumbled and before either of them could ask why, he was gone with them in tow. No one noticed a form of a man wearing a suit leaning against the kitchen wall. He smirked, eyes flashing black.
"Oh this just got interesting." Crowley laughed before he disappeared as well.
