Thalia_wong: Hello everyone. This is my first try at writing a fan fic. Please enjoy my little contribution.

*~*~*~*~*~( Chapter 1 : The plan)~*~*~*~*~*

~ Professor Agasa's house

Conan was at Agasa's house, checking on the development of Ai's work. Ai had made a lot of progress on APTX-4869 during the last few weeks and it seemed that the antidote was going to be make anytime soon. Ai walked in, clutching something in her hand and whispered something to him.

" You have made the antidote?" Conan exclaimed loudly, excited at being able to be turn back.

" Yes, and it would be permanent. I'm sure of the effects." said Ai smugly, holding up a small blue and yellow capsule.

" Give it to me then." smiled Conan, his hand open wide.

" Wait. I got a plan, Edogawa. To change you back and destroy the black organization at the same time. But I only got the outline..."

~ Mouri Detective Agency

" Shinichi, you are coming back this Saturday?" said Ran happily, glad that he was finally coming back. Tears of happiness appeared in her bluish purple eyes. " Yes, if there are no cases coming up." Conan was at the other side of the line, using the voice changer. " Okay, see you then." Ran hung up, whistling a tune.

" Father, Shinichi is coming back!!!!" said Ran loudly as she cleared her father's table which was piled with empty beers cans, sake bottles, old newspapers and cigarette butts.

" Huh? ...ZZZZ" Kogoro Mouri lifted his head up for a second and went back to sleep again.

" What should I do? A welcome party? Yes!" Ran mumbled to herself, tying up the bulging black trash bag.

Conan walked in, smiling brightly at her.

" Ran-neechan, why are you blushing?" He teased, even though he could guess the reason.

" Erm…nothing. Come on, let's go to the supermarket. I forgotten today's dinner." Ran dumped the trash bag on the floor and grabbed Conan's hand and ran.

Ai watched from a nearby alley, watching them with a heartbroken look.

~ Beika Supermarket

" Flour, sugar, eggs… any more to buy, Conan?" Ran asked, turning back to him, stopping the shopping cart. " You forgot the lemons." Conan answered her. " Oh! You wait here while I get it." She left the cart there and walked off to the fruits section.

He felt a piecing stare, icily and definitely hostile.

" Who was that?" Conan turned to look at one of aisles.

He thought someone was watching him. Possibly a member of the organisation.

" Must be a figment of my imagination." He reassured himself after checking the baker's needs section.

" Vermouth, Rotten Apple's protagonist has been found."

~ Mouri Detective Agency

" Shinichi…."Ran looked at Conan when they reached home. " Is he the same person as Conan? But it can't be, right? How could he shrink and grow at the same time?" She shook her head at the impossible thing, making a mental note to ask him about this little relative when they meet on Saturday.

" Ran-neechan, I need to go Professor Agasa's house. See you later!" Conan said and ran off quickly, taking the stairs two steps at a time.

" Remember to come back for dinner!" yelled Ran, staring after his retreating shadow.

~ Professor Agasa's house

" Professor, what do you think of our plan?" Conan asked when he had finalized the plans with Ai. " It is too risky. You should seek help." The old man felt unease at his and Ai's plan." I did. Heji is coming tomorrow and my parents are coming from America to assist in the capture of the members."

Sipping tea, Ai typed something rapidly on the computer. " I need something for me to distract Gin and Vodka." " You must be quick, or else you will be captured again." Conan was concern.

She wanted to destroy them personally for a reason she would not say.

" Don't probe. I know you know my reasons, detective."

" I has something for you, Ai." Professor showed her a pair of red and white shoes like Conan's.

"What is it for?" " To help you escape," replied Professor, lowering his voice and stating the uses quickly. "Are you sure it's in working conditions?" Conan stared, questioning at Professor Agasa. " Yes, I am very sure." he said annoyingly.

" Ai?" Conan asked when Agasa left the room to get more coffee.

"... " Ai choose to keep quiet and stared at the computer screen where millions of figures were rushing by.

" Don't you want to be yourself again?" " No." Ai replied simply." Why?"

" Even if the organization is destroyed, the remaining members will seek for revenge. I will be the first target. It's better for me to remain this way, an elementary school kid. " Ai replied, fingering her hair.

"…" Conan went into deep thought.

" Don't be like that, at least you will be Shinichi Kudo, the famous high school detective again." Ai patted Conan's shoulder and left the room.

" Ai…"

~ Mouri Detective Agency

Sitting down on the comfy sofa, she searched through the photo album and took out a photograph which was yellowed with age.

" If Conan is Shinichi, " Ran looked at the photograph of a younger Shinichi and Ran. " They looked so alike. Shinichi's mother denied when she saw Conan. But she could pretend Conan is not Shinichi. But Shinichi appeared at the same time as Conan last time. But Conan was not himself and Ai fell sick at the same time…"

" I'm home, onesan," Conan announced when he reached home." What's that in your hand?" He queried.

" Nothing. It's just a book." Ran lied, slipping the photogarph back into the album quickly and hid it behind the cushions.

" I will be in my room doing homework if you need me." Conan left.

Ran stared after him for a while. Shaking her head, she went into the kitchen and got her apron to make dinner.
