A/N This is just some fun babbles of what it would be like if John were The Doctor and Sherlock were his companion. I saw a list that had Martin Freeman as the number one choice for a Doctor regeneration and I fell in love with the idea. Enjoy!! <3

Sherlock was pressed against a wall, trying to control his breathing.

"Mr. Holmes, where are you?" The melodic voice echoed through the near empty halls, causing Sherlock's heart to jump. "Come out; come out where ever you are!" He scanned the room, desperately searching for a way out. The only thing he saw was a ratty old police box, buried in the corner. Hopefully it was empty, because that was his only option. He ran over to the box and pushed on the door, panic setting in when it wouldn't budge. He desperately reached into his pocket to grab his tool kit, throwing desperate looks back towards the hall. He kneeled before the door and started to try and unlock the door, only to find that his tools were not working.

"Mr. Holmes?" That voice was getting closer, now accompanied by footsteps echoing off the walls. Sherlock tried to force the door open once more, still kneeling in front of the blue box. Maybe he could talk his way out of this, though he wasn't sure his pursuer was really interested in hearing him talk. He rested his head against the cold, unforgiving wood of the box. He was shocked back to reality when the box started to hum, vibrating beneath his weight. He threw himself back, landing rather undignified on his backside. The whole box was lit up from within, a soft blue light emanating from the white windows.

"What the-"

"Oh she likes you." A new voice appeared behind the detective, causing him to spin around. The man that stood over him was smirking down at him, looking confident and brave. Sherlock tried to deduce the man but couldn't get anything from him, distracted by the angle he was looking at him from. "Well?"

"W-well-" He couldn't make his voice stop trembling.

"Well we can't just stay here. Not with that Succubus on your tail." The man grabbed Sherlock's hand and hauled him to his feet. He wasn't as tall as Sherlock had initially thought, standing a solid three inches shorter than him. His grey hair was slicked back with product, making him look dignified and intelligent. He smelled like pine and suede, and something unidentifiable. Sherlock rather enjoyed the scent. The man flashed Sherlock a quick smile and reached for the door of the box.

"It's locked." The man glanced back at the detective and raised an eyebrow. He scanned Sherlock, eyes travelling from his head to his feet.

"Oh no Mr. Holmes, she would never lock me out." He pushed on the door, shock filling his eyes when the door refused to budge. He turned and glared at the box, shaking the door and cursing. Both of them froze when a voice cut through the air.

"There you are Mr. Holmes. And I see you found a friend." Sherlock turned to see the creature that stood before them. Standing at nearly seven feet tall, the feminine creature appeared to hover above the floor, her sheer robes flowing behind her. Everything about her defied everything Sherlock thought he knew. His mind hurt seeing her standing there.

"What, pray tell, do you want with him?" The strange man spoke, spinning around and stepping confidently towards the woman. He pulled a strange looking device out of his pocket and pointing it at the woman. He pressed a button on the device and it made an irritating sound. It was some kind of sonic technology; that much Sherlock could tell. But what it did he couldn't even begin to guess. He stopped the sound and looked at the device as though he was reading it. "I mean I can understand why you would choose him, he is gorgeous." Sherlock felt his cheeks heat up at the complement. "But what is so special about this man that you would travel across the galaxy to try and take him?" The man was mere inches from the being now, though he didn't appear to be afraid.

"His mind is needed." The simple reply the man received seemed to confuse him, as he spun to face the detective. He stalked back to him and looked up into his eyes, questions filling the dark orbs.

"What is so special about your mind, Sherlock Holmes?" Sherlock raised his eyebrow; did this strange man know his name but nothing else? "Well I mean besides the obvious." He winked at Sherlock, once again causing a blush to creep along his cheeks. How can this man draw these reactions from him? Who is this mystery man?

"His mind is needed for the cause." That caught the man's attention, causing him to pull his eyes from Sherlock's and face the creature again.

"Well that is interesting. You lot are usually so boring, flitting about and stealing life forces. Now you have a cause? Well you officially have my attention, and that isn't something you necessarily want." He had been talking rather casually up until that last sentence. At that point, his voice lowered, becoming almost a growl as he stalked back to the creature.

"And why would that be?" The question fell from Sherlock's mouth before he could stop it. The man glanced back at him, amusement in his eyes.

"Take a guess Mr. Holmes." He spun around and stared intensely at the detective, the intensity of his gaze bringing yet another blush to Sherlock's face. "Show me that brilliant mind of yours." Sherlock straightened, running his eyes along the man before him, his mind picking out details as he did so.

"You are a well-traveled man, though you would prefer to stay at home. You have seen war. More than one judging by the way you carry yourself. You have forced yourself to live a life of solitude, a new decision as you recently lost someone important. You have a strong moral compass, but you are not opposed to making the difficult choices when the need arises. You come off as someone a person could easily be friends with but something about how you look at people tells me you don't believe yourself to be worthy of friends." Sherlock had walked closer to the man as he spoke; now standing inches from the shorter man. "People fancy you a hero, but you consider yourself to be more of a curse. How many lives do you carry on your shoulders?" Sherlock whispered the last question, gauging the man's reaction. He tensed, blinking furiously and flicking his tongue out to lick his bottom lip. Sherlock smirked; he always loved getting under people's skin like that.

"Oh you are good aren't you Mr. Holmes?"

"I am the best."

"Modest, I like that." Cheeks flushed.

"However there is one thing I don't know yet."

"And what would that be?"

"Whatever is your name?" Another smile pulled at the man's lips, causing Sherlock to smirk as well. It felt like they were flirting.

"Ah yes. We haven't been formerly introduced yet have we?" He spun back to the creature and pulled the device out of his pocket once again. "I am sure you have heard of me you stunning thing." He pointed the device at the strange being before him; grinning as he did. "I am feared across the universe. My name can cause wars to cease and the strongest of warriors to tremble in fear. I have destroyed planets and ended the biggest war this galaxy had ever, and will ever see. Have you figured it out yet? Who am I?" The creature screamed and lashed out at the man, Sherlock reacting just in time to pull the crazy man out of the line of danger. The two men scrambled back towards the box as the creature started to chant in some foreign language. The man reached for the door of the box once again, causing Sherlock to blanch in shock.

"It's still locked!" Sherlock shouted at the shorter man, earning a harsh glare from the shorter man. He rested his forehead against the box, muttering and shaking the door. He slammed his hand against the door and it opened.

"There you go you sexy thing!" The man shouted at the box, causing Sherlock to raise an eyebrow. He felt a hand on his arm and was pulled into the box, preparing for a tight squeeze. He never got that though.

"What the-"

"Yes, yes. It's bigger on the inside. I have heard it all before. Now we have a very pissed Succubus out there, how do we stop it?"

"How the hell am I supposed to know?"

"You are great Sherlock Holmes, the infamous Reichenbach Hero. You were able to tell more about me than anyone ever has with merely a glance, and you are telling me you can't figure out how to kill a Succubus?" He was standing next to a huge control panel, flipping switches and pressing buttons.

"Can we just shoot it?" It was ridiculously simple, but Sherlock had learned years ago that sometimes the simplest of answers were the correct ones. 'Not everything has to be a puzzle you clot.' His brother's voice cut through his mind, almost causing him to flinch. The man spun to face him, his face filled with curiosity.

"Shoot it?"

"Yes. Shoot it."

"I don't have a gun."

"I do." His eyes filled with amusement as Sherlock pulled his handgun from his trousers, presenting it for the man before him.

"Of course you have a bloody gun. I don't like guns."

"I do." Sherlock's snide comment drew a laugh from the shorter man, who ran his fingers through his hair as he walked towards the detective. "But first, you still haven't introduced yourself."

"Right, sorry. People call me The Doctor."

"The Doctor?"

"Yes."

"The heroic title I presume?"

"Yep. Now, let's go kill us a Succubus." He winked at Sherlock and raced to the door, Sherlock following close behind. The Doctor opened the door and was immediately dragged out by the Succubus. Sherlock leapt after him, pointing the gun the offending creature. The Doctor was in the grip of the beast, trying desperately to avoid the deadly spike that was protruding from the creature's wrist.

"Doctor?" Sherlock was uncertain for the first time in his life.

"Anytime you are ready Mr. Holmes." His voice was strained, and held a hint of panic. Sherlock was a good shot, but the two of them were moving an awful lot and he didn't want to hit his new friend.

"Hey!" He shouted at the beast, catching its attention. The beast turned and screamed at him, dropping the Doctor as she did. He fired; a true shot. The beasts head whipped back and it hit the ground, finally falling silent. The two men were still for a moment, taking stock of what just happened.

The sound of laughter filled the room. The doctor was laughing, and soon after, Sherlock joined him.

"So Mr. Holmes, what is it you do exactly?" The Doctor asked, finally catching his breath and climbing to his feet.

"I am a consulting detective. What about you?"

"I travel through time and space." Sherlock laughed, not at the strange man's claims, but at the fact that they didn't surprise him. "Want to come?" Sherlock was shocked.

"Do I have to call you Doctor?"

"Well I don't have any other name."

"I won't call you Doctor." They were standing inches from each other now.

"Then what will you call me, Mr. Holmes?"

"John. I shall call you John." His eyes filled with shock at the name.

"Alright, but I am calling you Sherlock."

"My dear John, I wouldn't have it any other way." He smirked as John grinned. They walked to the box and climbed in, starting on one of the greatest adventures either of them would ever experience.
