This story is about if Conan and Shinichi were both the same person and not the same person at the same time. Instead of Shinichi turning into a child, Shinichi was duplicated, and his double was a child with an identical nervous system (Brain, memories, personality, mind, intelligence, etc.).

When Shinichi woke up after being hit on the head and poisoned he saw a little kid stuck in his clothing. The thing is, this kid was naked and identical to his younger self.

"Uhm… did that poison make me give birth to a seven year old?" The older Shinichi asked.

"I doubt it, because I'm Shinichi too." The younger Shinichi said.

"Prove it, if you were me then when was the first time Ran and I kissed?" Shinichi asked.

"You haven't." the youth said.

"Where was I when promised to bring Ran here? And what the condition to the promise?" The teenage detective asked.

"The aquarium case, and it was if she won the karate competition." The youth answered.

"What was the resolution of my last case?" The teenager asked.

"You let the culprit go because she was sorry and no deaths actually occurred. Instead of throwing the actual culprit in jail you told them that it was the recent serial murderer and you gave them the serial murderer's identity." The clone answered.

"I guess you actually are me… I would've been less surprised if I just shrunk into a child rather than having a child clone." Shinichi moaned.

"We… uhm… how do we refer to each other?" The youth asked.

"As different individuals. You'll be a distant relative to people who won't be given the secret. Let's go to Hakase's." The older Shinichi suggested.

"Yeah."

After getting Conan clothing from his house and going to Agasa's…

"Boom!" was heard outside of Hakase's.

"Professor, I need your help!" Shinichi yelled.

"Yes, what is it Shinichi m'boy! And who is the kid!" Agasa-Hakase yelled.

"Yeah, I need to explain the predicament inside, the kid is coming along too." The teen answered.

After explaining a little…

"So… you are both the same person and not the same person?" Agasa asked.

"Yeah, basically, and I did interrogate him, he knew stuff that the criminals wouldn't know no matter how much digging they did. Just in case could you do a fingerprint scan on him?" Shinichi asked.

"Oh, still don't trust me, eh? I guess that is to be expected from me." The youth laughed sourly.

"I suppose I wouldn't be happy if I was turned into a child… hopefully we'll eventually be able to incorporate you into myself again. I'd feel bad to take Ran while you're left with little kids." Shinichi laughed.

"Well, I'll go think up a name for myself. I'd hate to be called '...' for the rest of my life." The youth said after Agasa took his fingerprints.

After a couple minutes…

Ran ran into the house. She then yelled, "Shinichi?"

"Huh? Ran!" Shinichi yelled nervously.

"There you are! I was so worried. Wait… why did you ditch me?" Ran yelled.

"Uhm… y'see, my parents sent a distant cousin of mine to stay for a while, and I needed to come back right away. I was just about to inform you." Shinichi lied.

"Oh! A distant cousin! Can I meet him?" Ran said ecstatically.

"Oh… in a minute, let me just go check on him." Shinichi said loudly.

"Okay?" Ran said, she felt that Shinichi was acting weird.

In the other room…

"Have you thought up a new name?" Shinichi asked.

"How about Sherlock Conan? Conan Holmes? Arthur Holmes? Ranpo Holmes? Arthur Edogawa? Conan Edogawa?" The child asked.

"Okay Conan Edogawa. I'm gonna go to America where I can get my parents to help. I mean, our parents. Uhm… anyways, I'll use Mom's perfect disguises to help you from close by. Before I go I'll give you a large amount of money to use. Don't spend it unless necessary… and for buying mystery books. Oh, and I got these when I was at our house." Shinichi brought out a large pair of his father's old glasses. He put them on Conan's face.

"Well, I suppose they'll be fine once I have Agasa-Hakase fix the prescription. For now I'll just deal with it." Conan sighed.

"Ata-boy. Also, if possible I'll try making it so you can stay at Ran's. As you know her father is a terrible detective. It will be your job to make him famous so we can get cases involving the men who poisoned us. I'll have Agasa-Hakase fake you an identity. That should be it." The older self summarized.

"At R-Ran's?" Conan stuttered.

"Don't fail me, bring me back some good memories of living there." The teenager laughed.

"I don't remember being so much of a perv." Conan muttered.

"Sheesh, I was only joking, don't do anything that would make her suspicious of you, like, I don't know, peeking." Shinichi joked.

"Aye, Aye." Conan answered himself.

The two halves of a whole walked out of the room. Before Ran noticed the kid leaving the room, Agasa gave Shinichi a big thumbs up indictating that Conan was indeed Shinichi. Due to this, Shinichi asked, "Hey, Ran, I have some urgent business in America, so can you take the kid?"

"Wh-what?" Ran screamed in shock.

"It is very urgent, I need to tell my parents about it right away. And then I also have to tell the various secret services around the world, like MI6, FBI, CIA, Interpol, CISC, PSIA, NCA, and the TFI. I mean seriously, which is more important, something that Interpol needs to know, or me taking care of a kid?" Shinichi lied.

"S-secret services? Interpol? T-this sounds very important… Wait! How did you get involved in something like that?" Ran asked.

"On a more important note, if anyone asks if you know where I am, just say that you don't know. If they ask if I'm alive, say either 'I hope so' or 'I have no clue'." Shinichi said, avoiding the question Ran asked.

"Answer my question!" Ran ordered.

"Wow is it hot in here. I gotta go before it is too late. Bye! Take care of the kid in glasses for me!" Shinichi said grabbing his passport off a nearby table then leaving.

"Oh! Shinichi!" she yelled, but it was already too late, Shinichi was gone. She then turned to look at her young charge. She was instantly elated from her grumpy mood, "Oh! You're so cute! What is your name?"

"C-Conan Edogawa!" The young child answered.

"Who names their child that?" She said, then realizing how rude she was, she said, "Not that there is anything wrong with unique names!"

"Nah, it is fine, my parents and I are both avid mystery fans!" Conan said truthfully.

While walking home from Agasa-Hakase's house Ran and Conan had a similar chat to that in the second episode in the anime. Everything happened near-identically until the first time Ran accused Conan of being Shinichi.

"Wow, you are really smart Conan-kun. Much smarter than Shinichi was at your age." Ran commented after she saw Conan speed through the medical files and give his deduction.

"A-Am I?" Conan stuttered nervously.

"Yeah. Infact I'd say you're about as skilled as Shinichi is now! Can you tell me how that is possible? Not to mention that fact you seem to be so similar to Shinichi in every other way as well." Ran asked, genuinely puzzled, she obviously didn't think that Conan and Shinichi were the same person.

"I'm not as smart as Shinichi-niichan! That isn't even possible! Not even the best detective in Tokyo could beat Shinichi-niichan at deductions!" Conan said, putting extreme emphasis in his childlike voice, "If that isn't enough to convince you, just ask Shinichi-niichan!"

"Moah, I don't even know his phone number." Ran said while looking up at the ceiling, she then turned her head back to where Conan was, but he was gone. She turned more and found that Conan was emphasising his childhood even more by playing a handheld game from the bags of toys that had been sent to the doctor. "Moah, Conan-kun, what are you doing, those aren't yours!" Ran said.

"But I love this game!" Conan said with an extremely childlike voice and smile, but suddenly it faded, "Ran-neesan, get Ojisan and Ogawa-san! Hurry! Yuta-kun is in danger!"

"Y-yes Conan-kun!" Ran said, astonished by how easily the boy's facade faded when someone was in danger.

When Conan kicked the soccer ball and broke a tree…

Something passed her head just a minute ago, a tree was broken, the weapon was on the ground, Conan was lying down, and now the culprit was apologizing to the doctor for what he had done. Was Conan-kun the one who did that? Ran thought to herself.

Later when Ran decides to confront Conan-kun about this

"So, Conan-kun, how did you kick a soccer ball hard enough to break down a tree?" Ran asked, but was then interrupted by a phone call.

"Unknown caller, eh?" Ran muttered to herself. She picked up the phone and said, "Mouri Detective Agency, I'm sorry but Mouri Kogoro is out at the moment."

"Well, that's fine, I'm here to call you, Ran!" Shinichi said.

"Sh-Shinichi?" Ran asked.

"Yeah, the kid called me, he said something about you saying that he was as good of a detective as me." Shinichi explained, "Now, as much as I think I'm a great teacher, I don't think he is nearly as good as I am."

"T-teacher?" Ran said, shocked.

"Yeah, taught him everything he knows." Shinichi bragged.

"Wait, but that doesn't explain how he broke down a tree by kicking a soccer ball!" Ran said exasperated.

"The tree was probably rotten, it wouldn't have taken much to knock it down. Even so, he is strong for a kid his age. I can't blame you for being amazed by both his intellectual and physical abilities when he is only a first grader.

Ran, who now felt silly, said, "Oh…"
