Demon Deduction

"Hurry up John before it gets away!!"

"Wait...it? W-what...d-do you mean...it?" Dr. Watson slowly stopped running.

"Yes it, now come on before we lose it!" He yelled back to Dr. Watson. 

"Bobby? You called?"

"Yeah, I have a job you two idjits."

"Alright, where is it?"

"Where?!?"

"Bobby said it was in London. We have to meet up with some guy named Sherlock or something like that."

"Wait!! Sherlock Holmes?" Sam replied excitedly.

"You know him?" Dean asked. 

"No, but I read his partner's blog all the time!"

"Wait, Sammy, where are you going?"

"London!!"

When their plane landed in London, Dean had a hard time keeping up with his little brother which, at the moment, seemed like his kid brother. One second he was looking at a map, and another he was being dragged around by Sam up and down every street. "Can't we just get a cab?"

"I know the way Dean. It's just across this street!"

"Here we are, 221B Baker Street." Sam said blissfully. 

"You must be Sam and Dean. I'm-"

"Doctor John Watson!!" Sam interrupted. "I know all about you and Sherlock Holmes. I read your blog. My favourite one is "A Study in Pink." And I just find The Science of Deduction absolutely interesting!"

"Ha well, you will have to talk to Sherlock about that." Sam's eyes widened with excitement. "Right this way." He then proceeded to lead the Winchesters upstairs. 

They opened the door to find non other than Sherlock Holmes himself, standing by the window, playing his violin,  deep in thought. "Sherlock," John called out. "Sherlock the Winchesters are here." He looked the two up and down briefly, but took a second look at Sam. 

Something about Sam caught his eye that made Sherlock want him. Dean saw him eying his brother and stepped in front of Sam and glared at Sherlock. "I'm Sam and this is my brother Dean."

"I'm Sherlock Holmes. It's a pleasure to meet you." He took Sam's hand into his and kissed it gently. Sam blushed deeply, but Dean, on the other hand, got very jealous and pulled him back closer to him. 

"You two are very close. You've gone through a lot together. By the scars all over you, the two of you must spend a very large amount of time chasing after these creatures. Dean, you stand very close to your brother and and glance over at him very frequently over protectively. By the smell of your breath, you have drinking problem but are too proud to admit it. But Sam, you try to look like you have it all together, but your hands are shaking terribly and your eyes keep flicking around the room, caused by an addiction of some kind. Cocaine maybe." Both brother's eyes widened at this comment and Sam backed up self consciously. 

"I apologise Sam. I hope I didn't overstep my boundaries."

"Just leave it alone Holmes." Dean growled. 

Sherlock cleared his throat. "Well, Dr. Watson and myself have been chasing after this man that has committed multiple murders other the past two weeks."

"Okay, if it's just a dude, why bring us here?" Dean questioned. 

"This woman has back eyes and has unusual powers." Watson answered. 

Dean's shoulders dropped then looked at Sam, who's face went pale. 

"Alright, Sam I want you to stay here." 

"What?!?" Sam exclaimed.

"And Dr. Watson can you stay here and keep an eye on him?"

"Erm, sure."

And with that, Dean and Sherlock headed out after the demon. 

A few hours later Sherlock walked through the door to his flat. 

"Where's Dean?"

"He's down stairs eating some pie."

"Of course."

"John, Mrs. Hudson said she wanted your help."

"Alright."

After John walked out, Sherlock locked the door and turned to Sam, but when he spoke, his voice was unusually high. "Miss me Sam?" Sam's eyes widened. 

"Ruby..?"

"Hungry babe?" Ruby's eyes turned black and slowly walked towards Sam. He sat there, staring at her, both terrified and excited at the same time. Ruby pulled out a small knife and went to cut her arm but Sam stopped her. 

"Look where you're standing." She looked down to see a Lesser Key of Solomon under her feet. 

"You tricked me!!"

"Regna terrae, cantate Deo, psallite Domino

qui fertis ascendit super caelum

caeli ad Orientem

Ecce dabit voci suae vocem virtutis,

tribuite virtutem deo."

"No!!!" Ruby screamed as she was forced out of Sherlock's body. 

Sam ran into the kitchen and filled an empty milk jug with holy water then rushed downstairs. 

"Dean! John! Where are you?" Sam called out as he ran downstairs. He stopped shortly outside Mrs. Hudson's door and listened closely. He heard a bunch of muffled sounds and a few voices through the door. Sam tried opening the door but it was locked so he kicked it in and saw Dean, Dr. Watson, and Mrs. Hudson tied up on the floor. He rushed over and untied them. 

"Sam! It's Meg!" Dean exclaimed. 

"Hello boys." Meg said as she stepped out from behind a door. "It's been a while hasn't it." She smiled. 

"And it's gonna be a little bit longer." Sam said as he threw the holy water on her. 

"Exorcizamus te, omnis immundus spiritus,

omnis satanica potestas, omnis incursio infernalis adversarii,

omnis legio, omnis congregatio et secta diabolica.

Ergo, draco maledicte.

Ecclesiam tuam securi tibi facias libertate servire,

te rogamus, audi nos." Dean  yelled as Meg screamed in pain. 

"Thank you again Sam from saving me from that demon." Sherlock smiled. 

"No problem. If you ever need our help again, you know how to reach us."

"Yeah yeah, stop being gay and let's get a move on. I miss me baby." 

"Your car can wait five more minutes Dean." Sam said as they walked out the door.
