The Doctor's eyes spoke to him more than his words did and Sherlock felt every inch of his body melt- traveling, through all of time and space; he may never be bored again. The Doctor could see his thoughts clearly, and Sherlock questioned what abilities that he may exhibit as a time lord; could he read his mind? Images of John suddenly flashed through his own, of Lestrad grasping him and screaming- they would all be in panic now; there could be search groups out looking for him; what a waste of tax payers money. John would have left Sarah mid dinner, rushing out in the cold and rain to find him; he would search for days- weeks if he had to, and Sherlock knew he would never give up. His heart began to pain thinking of John, could he leave him so easily? London and the world he knew inside out, John wouldn't be able to pay the rent on his own- he would be forced to move into a share house and then…

Sherlock realised that his breath had become very loud, his eyes darting around whilst he thought "You can't leave him behind can you?" The Doctor suddenly asked, and Sherlock let out a heavy sigh, "Him?" He asked, although he was aware that The Doctor had deduced it himself, and received a sly smile from the time lord.

"The risks don't worry me," Sherlock said, turning away from The Doctor "I am well aware that I could be killed at any instant traveling with you-"

"But has that ever stopped you?" The Doctor asked, with a wicked smile on his face; there was a silence and the TARDIS made some strange noises but The Doctor did not seem stirred. The space in the TARDIS was wide and appeared draftee but the room was warm and comfortable and Sherlock could feel himself start to relax more and more; although he still remained very cold faced; not that this seemed to confront The Doctor, as it did to most people; it was as though The Doctor could see right into him- and he could see The Doctor; a strange connection that he had held with very little people- often not even with John. He was talking to a man who could for once, had seen and understood more then him perhaps; and although it was confronting, it was rather exciting.

"Never" Sherlock answered outright, he suddenly felt the need to push The Doctor away; he knew that if he did not leave soon he might become rapped up in something that he could never escape. The Doctor seemed to understand his sudden fear

"Why do you do it then?" He asked with a sudden panic in his voice, he had found a human beyond any other he'd ever met- he was not going to loose him so quickly. He could never force someone to stay against their will, but usually they weren't so hard to make stay when he wanted; but Sherlock was different and he understood this- a man of intelligence almost of his own and a man that he may finally be able to connect with. He found male humans always the hardest to befriend, females were often easy to charm and impress; but males were too competitive and difficult to understand, but Sherlock had hit a chord in his hearts- perhaps he could finally have an equal that was not insane, as The Master had been.

"Why do I do it?" Sherlock asked back, sarcastically as though the question needed answering. He stared at The Doctor, his eyes deep and fixed on himself, Sherlock's eyes trailed over the infrastructure of the TARDIS and was once again taken back in awe; shapes and colours he had never seen; technology that he had never touched or even been able to invent; this place was truly his dream; if he had ever conjured such a thing.

"I do it because everything else is so-"

"Boring?" The Doctor finished his sentence for him, his tongue playing with his teeth; he was smiling cheeky, hands in his pockets. Sherlock was taken back, but suddenly understood. He walked towards The Doctor,

"Can you read my mind?" He asked, not jokingly

"I can, but I haven't been" he answered, "Sherlock I don't know how else to say this, but I honestly don't want you to leave"

Sherlock felt his chest tingle, but he remained composed "I have other things... the case I'm on…" he felt his chest heave, how could be seriously believe any of those things were important now when he had this opportunity? But a sudden coldness washed over him, and he understood he could never truly leave it behind; he couldn't not let himself stay.

"One flight?" The Doctor asked.

Suddenly there was a rush of sound and flashes erupted from the control panel and a screen flipped on, shapes flashing. Sherlock was shocked, but The Doctor once again didn't seemed that fussed, only annoyed "Oh! Alright, alright I'm coming!" he walked over and began to flip some buttons and pull leavers mumbling to himself, his behaviour and indulgence reminded Sherlock of someone- himself.

"What's happened?" He asked, very curiously. The Doctor didn't turn back, and instead pulls out some glasses from his pocket and placing them on his angelic face- although Sherlock was well aware he did not need them. "Oh, the damn thermostat has been trying very hard to keep balance so the freibondator is having trouble remaining connected to the CAL cord and now the thermostat is refusing to stay on one temperature- she's one moodily girl today!" the way The Doctor spoke caused Sherlock to gush to himself slightly, the raw intelligence that seemed to fall off his tongue was thrilling. The Doctor pulled down a lever and made a sound of triumph, pressed something and spun around throwing his arms up in the air, "Oh, I'm brilliant! Saving someone and reconnecting the CAL cord in one day, I'm on fire!"

Sherlock smirked to himself, he wasn't usually so caught up in other people enthusiasm but The Doctor brought him a sense of comfort and enjoyment, as he understand that the other man seemed to be truly intelligent. The Doctor faced him and leaned against the panel watching him and Sherlock walked up to the panel once again to study it.

"So what exactly can this TARDIS do?" He asked and smiled, The Doctor leaned in towards him "Let me take you on a trip and you'll find out" Sherlock looked directly into his eyes, "You are certainly trying your hardest to excite me aren't you Doctor?" He asked, his voice monotone "I must say that your invitation in inviting…"
"Well let me excite you more then" he answered and quickly pulled something out of his pocket, pushing it in front of Sherlock's eyes, "Quick he answered, tell me what you see!"

Sherlock stood watching him confused, yet highly entertained "It's paper designed to appear as whatever you expect to see..."
"Good…" The Doctor answered slowly "Very good"
Sherlock felt a warmness inside, the type he felt when he always deduced something correct- the feeling of understanding and confidence; yet it was not always attached to such a feeling of excitement, as most things were so dull.

"It would work on most weak minds" he continued "But for me, all I see is blank paper" he smiled to himself and The Doctor put it back into his pocket

"You're the second person I know that it hasn't worked on" he said with a grin, "Who was the first?" Sherlock asked.

"Shakespeare."

Sherlock understood what he said, yet he almost did not allow himself to compute it and within that moment he understood; he couldn't let this opportunity pass. Suddenly The Doctor was very close and he could feel his heart racing

"It has been awhile hasn't it?" he asked, The Doctor seemed to be momentary confused, what was he thinking he meant?

"Since you've had a passenger, Doctor" he continued "Judging by the state of your clothes and smell of your breath you haven't changed or eaten in more then 2 or 3 days; I'm sure Time Lords don't need to eat or have the same personal high gene standards as humans do but you seem to be struggling to remember those habits." The Doctor looked at him, not confronted yet serious

"I haven't slept for 2 days" he answered, "But as I observe from your posture and the colour of your eyes, you haven't either." It was true; Sherlock had been struggling to stand up for the majority of their meeting- tiredness beginning to perhaps finally grip him,

"Maybe you should sit down," The Doctor said, and attempted to move him back towards the chair "I'm perfectly fine standing" he answered, although his voice and low; his breath deep.

"Humans will start to struggle tremendously without food or sleep for 2 days" he said, and moved in closer towards Sherlock; "They may even start to see things…" Sherlock understood what he was implying "I think you would have understood that this is the diet I undertake for most of my cases" Sherlock said, his voice beginning to weaken slightly.

"How do you know this isn't just a dream?" The Doctor asked, his voice low

"There is no likely hood that this is a dream," Sherlock almost snapped back at him yet The Doctor did not seem taken back and if anything more intrigued.

"And that's what makes you brilliant Sherlock" The Doctor answered.

Sherlock watched him, The Doctor smiling; his face calm and knowing. "Let me take you" He said softly and moved in closer. Sherlock could feel questions running through his mind, he was not aware of the laws of time, he could not grasp that reality; as he did not have the knowledge to do so, and it disturbed him. Yet, how was he to learn unless he discovered them?

"One trip?" He asked, his voice low; the doctor was closer physically then he'd been with another for a long time; and the look in his eyes told him all he needed to know.

"Yes" he answered "But I warn you Sherlock…" suddenly stepping back and looking at him very seriously "Once you go on the first trip, you can never stop."

"I know" Sherlock said, "It's obvious you never did." The Doctor looked at him quizzical, Sherlock's inability to understand emotions was even slightly comforting; yet even if he could not understand them he could always detect the signs.

"And one more thing" Sherlock continued "Before we go on this 'first trip' I need to ask you a question" The Doctor was intrigued "What?"

"What's this?"

And with a sparkle in his eye Sherlock pulled out a strange small thin device, first appealing like an eccentric torch but under more inspection is seen to extend and admit sound, a blue glass covering the top. The Doctor stood staring whilst Sherlock watched him with a sly glare.

"Why you're…"

"Brilliant? Oh come now, it wasn't that hard to pickpocket you at that proximity"

The Doctor stood smiling at him, awe on his face

"Fantastic!"

"That's not the reaction that people usually have when you pickpocket them"

"Yeah well… maybe it's because they weren't pickpocketing you too!"

And with a small flick of the hand The Doctor produced Sherlock's magnify glass from his sleave. Sherlock felt his chest tighten, and draw a deep breath; it had been years since anyone had been able to pickpocket him. The Doctor must have understood as he watched Sherlock with a look of thoughtfulness, smiling cheekily.

"How-"

Sherlock thought over the moment that he'd pickpocketed The Doctor and not once piece of evidence or action he cold detect the moment he'd been deceived. Suddenly the feeling of shock washed over him.

"You fooled me"

"Did I?" The Doctor knew he had "But you fooled me as well"

Sherlock smiled "I'm usually very good at that"

"Oh, but I'm not an easy man to deceive." The Doctor winked, he meant it in good nature. They watched each other for a moment and Sherlock could see something in The Doctor eyes, something he couldn't understand.

"So you want to know about my sonic screwdriver do you?"

"I see, it doesn't wound does it?"
