Teen AU-When Sherlock and John enter a partnership-Sherlock to appease his parents, John because he wants to-neither of them thought they'd actually get along. As their friendship progresses, both are surprised to find that they get along better than they first thought. But what will happen when feelings start to become less platonic than they were to begin with? Will Sherlock run?

It all begins with a paper airplane thrown from several stories up, found by a little boy named Sherlock Holmes. In the window above was a boy named John Smith, who, more than anyone there, knew that he was different. Sherlock could easily deduce that he was insane based on how he spoke and what he said. But how could he destroy a delusion so pure?

John Watson thought this was it for him after he returned from Afghanistan - runny noses and the tedium of working a job at a private practice. Aimless and bitter, he never thought he would find his purpose again. Enter Sherlock, a little boy desperately needing rescue from the wreckage of his life, and John gets more than he ever thought possible...a family. Kid!lock.
