John sighed as he walked to the cafe at the corner during lunch break. The patients at the practice were particularly boring this week, all of them having nothing more than a dripping nose due to allergies.

I'm beginning to sound like Sherlock. John thought, shaking his head slightly, a smile coming unbidden to his face.

He walked into the restaurant the door closing behind him with a slight bumping noise, and jingle bells tinkled where they were tied to the top of the door. John immediately walked over to his usual table, and sat down across from his friend Dr. Jonas Winthorp III, known only to his friends as Trey, meaning, "the third". It was actually John that had suggested the nickname after they had met in the practice awhile back.

"I think I've been spending too much time around Sherlock lately." John chuckled as he sat.

"And why do you think that?" Trey asked.

"Don't you get all shrinky on me." John said. "You're a neuropsychologist, not a psychiatrist, remember?"

"Doesn't mean I can't be curious." Trey asked. "You've told me a ton about this Sherlock guy, but I've never actually met him."

"You ought to be thankful." John said. "Who knows what crazy deductions he would have about you."

"Well you don't seem to mind much." Trey commented.

"Yeah, but I'm used to him. You eventually become immune." John said. "He can be surprisingly... thoughtful, if he thinks the situation calls for it, which he usually doesn't."

"What's he done lately?"

And thus started the usual conversation between them. John telling Trey about Sherlock's antics as they ate lunch. Telling him about all the funny little quirks Sherlock had, for example, how Sherlock felt the need to have the door knocker in different positions depending on his mood. When he was angry and frustrated it was angled left, when he was happy and content, it pointed to the right, and when he was stressed and over worked, it would point up and down.

John told Trey how he had figured it out.

"Sounds like your picking up a few skills from the 'great' detective." Trey said, laughing and using finger quotation marks around "Great".

John frowned. "Don't do that?"

"Don't do what?" Trey asked.

"He's good at what he does, and I'm not going to let you act as though he's not." John said. "So don't be sarcastic. He deserves the title the Great Detective."

"I didn't mean it as an attack or anything. I know he's brilliant." Trey said, "I've picked up that much. Don't worry."

After a moment's hesitation, the smile picked back up on John's face, and he launched into another story of Sherlock's experiments.

"He blew the kitchen up smoke was everywhere, some of the tiles melted a bit, and you can bet Mrs. Hudson was not happy about that." John said. "It all worked out alright though, because he solved the case eventually by using a strand of the victim's dog's hair. "

Trey listened in fascination as John went on to describe the process through which Sherlock had solved the case.

"I don't know how he does it," John said shaking his head at the end of the story. "but he does, and he's right almost every time."

"Interesting..." Trey trailed off. "Do you think he might-" John cut him off right there.

"If you're asking if he'd let you do tests on him, the answer is no." John said. "It's a great idea Trey, really, it is, but from what I know, he's had very, very poor experiences with psychologists and psychiatrists. From what he told me, which isn't much, he usually just spouted off some deductions when they got too nosy. He actually made a few of them cry, and diagnosed one of them with cancer. As much as I think it'd be good for the both of us to figure out how that mind of his works, I don't think he'll do it."

"Well it's been awhile then, hasn't it? What makes you think he's not willing to even now?" Trey asked.

"Because he's Sherlock, and he doesn't change his mind easily. Plus he's not all that fond of Americans for whatever reason." John sighed. "But if it'll make you feel any better, I'll ask him."

Trey smiled widely, enamored with the idea of a new, brilliant, complex mind to analyze and untangle.

"Ah, don't get your hopes up." John warned. "His answer will probably be no."

"Yes."

John did a double take.

"Wait- what?"

"I'd like to meet him before I'll submit to testing of course, but I agree to consider it." Sherlock said.

John stared at him a moment, with surprise.

"Why?" He asked dumbly.

"Well, this is a neuropsychologist rather than a psychiatrist or a psychologist, which means he's likely to be more focused on the scientific significance of what is found out. Plus," Sherlock continued, "while you haven't taken much thought as to your own opinion yet, you seemed to be subconsciously pleased by the idea of knowing how my brain works. Though you don't know it yet, you feel very strongly that this is a good idea."

John blinked.

It was a good idea, wasn't it?

Hmm...

A/N: So, here's the first chapter of the story that I shouldn't have started until I finish some other ones, but I did anyway so oh well. Hope you like it, I'm anxious to see what the response is to this idea, because as far as I've seen, it hasn't been done before. It will be a sort of character study with in a story. Or rather, a story about fictional characters doing a character study on each other. Hm... Well I've made that about as confusing as I possibly could have. Anyway, enjoy!
