I do not own Detective Conan all rights belong to it's owner.

"The Black Organisation had been gone for a week now and your still not done Haibara." 7 year old Conan said while walking around the room with his hands be hide his head.

"I'm doing my best, Kudo-kun." Haibara said turning her chair around to face the boy. She looked tried like she was working without taking a break.

Conan looked at her and sigh. "Just don't work to hard. I could wait for a while before becoming Kudo Shinichi again." Haibara stared at him. "Just get some rest." He said then headed for the door.

He walked with his hands in his pockets while the snow fell down slowly. He made his way to the Detective agency and when he enter the first person he seen was Heiji Hattori. "Hattori!" Conan yelled.

Heiji turned around to face him. "Ku- Kiddo, hi"

Conan just gave him a annoyed look then walk in and sat on the sofa. Ran walked in front of the boy looking down at him with her hands on her hips. "Where have you been, young man?"

Conan jumped slightly then looked around to see everybody he knew in the small house. "Um..Why is everybody here?" He asked.

"Well, we all got invited to the opening of the new Nishitamashi Twin Tower building." Satou answer him.

"Eh?!" Conan stared at them then Kogoro spoke up.

"Remember you jumped across the broken bridge?" Kogoro looked at the boy. "Why did you do that anyway?"

"Umm...I was worry about the others and so I went to help them." He said in a childish voice while staring at them with big blue eyes.

"Well, get ready Conan-kun!" The detective boys yelled. He didn't notice when they opened the door.

"Alright." He said walking to his room when the door suddenly closed be hide him. He turned around and seen Haibara. "Haibara?"

"Kudo-kun, you need to take two pills so that you could be yourself again. You need to take the one in my right hand to clean your system and make sure that you do return to your original age. Then take the one in my left to turn into Kudo Shinichi again."

Conan nodded then walked over to her when Ran open the door, hitting Haibara making her drop the pills. "Sorry Ai-chan, but can you two hurry up?"

Conan nodded then Ran closed the door and he start to panic, along with Haibara. They both looked for the pills and found both of them leaving next to each other. "Why did you make them both red?!" Conan yelled at her.

"I don't know. Let me-" She stopped when she seen him swallow one of the pills. "Kudo-kun, what if that was the wrong pill?"

"I'm sorry, but how would we explain to them if they come in seeing pills on the floor?" Before Haibara could answer Ran opened the door and stared on the two who was on there knees. She looked at the pill then picked it up.

"What was you two doing with this?" She asked.

"Nothing we just found it on the-" He suddenly faint, breaking into a cold sweet. He was gasping for air while Ran picked him up and laid him down on her bed, she left the room then came back. She placed a wet cloth on his forehead then came out the room.

"I think I'm going to stay here." Ran said while everybody looked at her.

"Why, Ran-chan?" Kazuha asked her.

"Conan-Kun is sick and someone need to stay here to watch him." Ran answer with a sigh.

"I'll stay here and watch him." Satou said with a smile. "I didn't have anything to wear anyway."

"Thanks, Satou-chan." Ran said with a smile while walking out the door with everybody else.

Satou sat down watching the news, she would cheek up on Conan ever once in a while. She sat there watching the news then they said something about a man name Kisaragi Hosui breaking out of prison a few weeks ago. She just sat there listening to what they said about him when that suddenly said they had breaking news. They said that Kisaragi Hosui had blow up the Nishitamashi Twin Tower building, everybody was killed. Satou was freaking out not because everybody was dead, but how was she going to explain this to the 7-year old boy?

Conan had woke up now and could hear Satou talking to herself. He heard her say something about everybody dying, so he got up. He was dizzy and didn't notice that he didn't have to stand on his toes to reach the door nob. He open the door while holding the blanket around him. "What happen?"

Satou was shock to see the taller Conan. "Conan-kun, your tall and handsome." Satou said and notice the blush on the boy face.

Conan looked at his body and realized that he grow, but also realized that he was shorter then he was when he was Shinichi. He atomically knew that he was 15, which made him worry. "Um..what did you say about everybody?"

"Um..Everybody is dead, they was killed in a explosion at the Nishitamashi Twin Tower building." Satou said while the detective eyes widen and he fell onto his knees.

"Damn!" He yelled while punching the ground.

"Um..Conan-kun why are you taller?" Satou asked.

He explained to her, not telling her that he was Shinichi. He told her his real name was still Conan and that he was solving all of the cases that they been in.

"That's why every time when we was on a case it was solved quicker with you there." Satou said while staring at his body.

"Um..Satou-Chan do you have anything I could wear?" He asked while holding on to the blanket when he suddenly felt a wave of pain through his body. He fell forward once again losing consciousness.

When he woke up he was laying on the bed and staring into Satou eyes. She had her forehead press again his and blushed when she realized that he was awake. "Um...Your fever is gone and I got your clothes out. I also called the high school and told them that you will be coming in tomorrow." Satou said.

"Okay, I can take care of myself now Satou-chan. I'll just stay here until I could get a new place to stay and a roommate." Conan said to Satou with a smile."I must of took the wrong pill first and now I'm 15, the side effect must be the fever and pain I suddenly feel." Once it was late Conan finally realized what Satou had said before and broke down into tears. He had lost everything just by taking the wrong pill.
