Chapter three.

They were back at 221b, all trying to figure out what had become of Moriarty.

"Since when could people turn into demons?!" Sherlock asked.

"He could be lying." The Doctor proposed.

"Sorry John, but that was a demon." Dean said taking a sip of his beer. "Besides, when some souls go to hell, they get promoted to demon."

"Maybe it's not Moriarty." John added.

"Like it might be another demon pretending its Moriarty? Like using the body?" Sam repeated.

"Yes, I mean Moriarty's dead. There's no way they could bring him back."

Sam and Dean just looked at each other. "There is."

"Rubbish." Sherlock shot back.

"Well we know a few people it's happened too." Sam shrugged.

"Like?"

"You're looking at them." Dean and Sam replied.

The room went silent and John and Sherlock stared at Dean and Sam.

"No." John gasped.

"What?" Sherlock looked like he had been slapped.

"Well Sherly. We have died on multiple occasions. Simple enough for you?"

"Can we just stop for a moment and let the people who don't deal with Demons and aliens on a daily basis try and take this in?!" John barked.

"Aliens?" Sam questioned.

"That would be me." The Doctor raised his hand.

"No way!" Dean smiled.

"No way." Sam added seriously.

"Oh yeah, I'm a TimeLord."

"That's so cool! Do you know any like, Spocks or Martians?"

"I can't say I do, but I know some that are a lot cooler!"

"Shut up!" Sherlock roared.

Dean and the Doctor put up their hands innocently.

"Now how can a person come back from the grave?"

"You did." John grumbled. Sherlock shot him a look.

"There's a lot of ways." Sam replied.

"Well can't we just go back in time and stop it?" Sherlock rubbed his temples, like this was all too much of a headache.

"Afraid not, I can tell when something's a fixed point in time. This is, if we got rid of this all hell would break loose." The Doctor said.

"And if that happens again I ain't sticking around…" Dean muttered.

"Well how are we going to find him again? Killing him now isn't a fixed point is it?" Sam queried.

"No it isn't."

The Doctor seemed slightly distracted, constantly muttering to himself and other small stuff, this concerned Sherlock.

"Doctor?" He asked.

"Yes?" The Doctor put on a bright smile for them all.

"What's happened? And don't try to lie. I don't care if your rule is 'the Doctor lies' you can't lie to me."

The Doctor twiddled his thumbs. "When he said 'Spoilers', not many people know what that's from. So how did he know that?"

Dean shrugged. "Dunno, who would tell him?"

The Doctor waved it off as unimportant. "But what is, is how did he get out, I've visited a version of hell myself, it was in a deep dark hole-"

"Well you're not wrong." Sam replied darkly.

"Oh come on!" John said exasperatedly. "You've been to hell?!"

"Yes." Sam, Dean and the Doctor replied.

"How?!"

"Well, I sold my soul to resurrect Sam."

"And I've been in Lucifer's cage."

"And I, well, climbed down and then fell and met Lucifer, but he had no brain. I remember how odd the Ood were." The Doctor reminisced.

"Okay, but now, hell isn't easy to climb out I'm guessing."

Dean snorted. "Impossible would be putting it lightly, even demons hate it down there."

"Then how did he get out?" The Doctor asked slowly.

Dean looked to Sam. "Ten bucks says it was Crowley to raise some hell."

"I bet Lucifer."

"That's a bit much, don't you think?"

"The guy was in my head."

"WHAT." Sherlock snapped.

Sam and Dean looked around innocently, but even the Doctors eyes were wide open.

"Haven't you guys heard of a vessel before? The demons call us meat suits."

"A DEMON CAN TAKE OVER A HUMAN BODY?!" John screamed.

"Calm down John-"

"NO, I HAVE JUST FOUND OUT THAT DEMONS CAN POSSESS YOU. WHAT IF THEY POSSESS ONE OF US?!"

Sam shot John a look. "We know how to get rid of them."

John's chest heaved. Sherlock put a hand on his shoulder and looked into his eyes. John calmed down a bit.

There was a rapping at the door. The Doctor got up and answered only to be pushed out of the way by an angry man. His light brown hair was combed over and he wore a black suit with a bright red tie, he gripped an umbrella tightly.

"Sherlock!" The man snapped as he marched into the living room.

"Hello Mycroft." Sherlock replied.

"What is going on?!"

"What do you mean?"

"I mean Moriarty was dead. He just visited me in my office!"

"Well, that's awkward." Dean pointed out.

Mycroft looked around at their company.

"Sherlock, who are these people?"

"Sam and Dean Winchester." Sam greeted.

"Oh come on Mycroft, you know me." The Doctor chuckled.

"Of course I do you idiot. I didn't know who those two were."

"Somebody's crabby." Dean muttered.

"You would be crabby too if one of the worst criminals the world has seen was resurrected!"

"Been there. Done that." Dean shot back.

"This is no time for funny business you-"

Sam stood between the two men. "We have had a fair share of evil spirits, and Dean, we need to figure out what this is."

Mycroft stormed out of the room grumpily as Sam and Dean began to discuss what was going on.

"He's probably just a demon taking over a dead host." Sam suggested.

"That's probably it, but how did he know about doc's 'spoilers?"

"He said he had someone back in hell. Maybe it's somebody who has it out for the Doctor?"

"Any enemies' doc?" Dean asked him, watching Mrs. Hudson come up stairs with a man, a hood shadowed his face.

"You have a visitor Sherlock." She said sweetly.

"I don't have any time, I'm afraid you'll have to come back another day." Sherlock waved them off.

"I'm afraid this can't wait." The man said. He flipped his hood back revealing sandy hair and a cruel, menacing grin.

The Doctor stumbled back, his eyes wide. "No!"

The man smiled at the Doctor. "Yes."

"I sent you back, back into hell, back into the Time War!"

He shrugged in reply. "Well, you were right about sending me to hell, not so much the Time War."

The Doctor looked like he was going to be sick. "How did-"

"I know about River? Like Moriarty said, you observe a lot of things from hell, as long as you have the right connections, and by god that man has connections."

There was a click beside the man, Dean stood there with a gun cocked in his direction. "Don't move."

"Oh it's Dean! I've been waiting to meet you! And Alastair says hello, hope you're dying."

Dean pressed his gun to the man's head. "Who are you?"

"Ah, how rude of me. My name's the Master."

"Cocky much?" Sam asked, his gun also raised in the direction of the Masters skull.

"Hey, the Doctor chose his name. I choose mine." The Masters eyes were alive with insanity.

"What are you doing here?" John queried.

"I'm just popping in! Seeing if you've figured it out yet."

"Figured what out?"

"I'll never tell!" The Master cackled. Without warning Sam grabbed a bottle from his bag and splashed the contents all over the Master. The Master screamed and he steamed, he growled at Sam with black eyes.

"Demon!" Dean warned and shot the master. The Master hissed and lunged at Dean, knocking him to the ground. Dean scrambled backwards and the Master tried to catch him, but something was wrong. He couldn't move. He looked up and scowled when he saw a large yellow devil's trap.

"I hate you." The demon muttered.

"So, how'd you get out of the pit?" Dean smirked at the Masters scowl.

"I was promoted by the big guy."

"The big guy? Do you mean Crowley?" Sam asked.

The Master cackled. "Much bigger than that Sammy, you know who it is!"

Sam's jaw immediately clenched and he tensed. "You're lying."

"Am I? And Lucifer says that you'll be his vessel again, even if it kills your friends."

Dean snarled and splashed holy water over the Master, he hissed and writhed in pain.

"Give us information or we will send your ass straight back to hell."

The Master chuckled hoarsely. "Don't be so sure of yourself."

A loud explosion knocked off their feet. Debris of Sherlock's apartment flew everywhere and the Master stood there with a content look on his face, the devils trap was cracked and he strode out of the flat.
