A/N: This drabble is for my friend Brian, who came up with the idea, even though he doesn't watch either of these shows. I might turn this into a full length fic if it gets enough reviews.
The Doctor was never able to find a companion who listened to him, tell them one thing they do the other, at least it made life interesting. Sherlock Holmes was a whole other version of interesting, he was hard to live with, a smart ass, and believed he was always right, the Doctor thought of him as a best friend though.
The three suns of Xajer were setting and the Doctor found out, much to his dismay, that he left his sonic in one of the government buildings of the small planet. "Sherlock I am going out," the Doctor said as he put on his coat, "and for heaven's sake don't touch anything."
Sherlock frowned, "Would I ever?" he said in a fake shocked voice. He was sitting on the couch reading a long book only he would find interesting, something about cells in plants.
"Not kidding this time Sher, I am not saving you from any more exploding planets." The Doctor said. "I'll be back in five minutes, you can sit and read for five minutes can't you?"
"Of course I can." Sherlock said with a smile. The Doctor nodded and walked outside, taking in the smell of the Xajerian flowers. Sherlock shut his book. "Doesn't mean I will." He stood and walked over to the TARDIS, the Doctor refused to teach him how to fly, something about safety and the fabric of time ripping. Sherlock trusted himself not to cause to mush of a rip, he pulled some levers and pushed some buttons.
He pressed a yellow button with a warning above but the warning was in Gallifreyan, he didn't know the almost dead language. The TARDIS started spinning wildly and Sherlock got knocked into walls and tables. The curly haired genius noticed the oxygen in the room beginning to escape as parts of the walls were ripped off, revealing the darkness of space in time. He felt blood pouring down his face and the pressure was increasing, he was going to die, for real this time. He took what he thought was his last breath and the world went black.
Rose Tyler checked on the beat up man she found in the park, what were the odds that man surrounded by police box ruins was not associated with her Doctor? She paced quietly, a thousand things running through her head, no Doctor was found with the box, what if this man was on Mythbusters and he was testing the strength of a 1960s police box? No that was dumb. Well, she has seen stranger things happen.
Sherlock started breathing again and sat up, "Where the hell am I?" he asked, more demanding then he intended. He sat back again, flying up was not a good idea. "And who the hell are you?"
"You're in London 2019, my name is Rose Tyler," she replied. Sherlock stared at her for a minute.
"Rose Tyler? Stuck in another dimension Rose Tyler?" Sherlock asked and she nodded. "Well Rose Tyler, I'm Sherlock Holmes, and boy do I have quite the story to tell."
