A/N: You can tell in the beginning I wasn't really into it. Sorry.

"Hello?"

"Kudo-chan." Ai Haibara called into the phone. She had found it, the cure to the APTX 4869, the poison which had shrunk both her and Kudo.

Well, maybe.

The antidote had worked for a full two weeks on the guiena pigs and only one of them had died (which was an incredible feat for Ai). Ai had worked hard for she knew Kudo desperately wanted to leave Conan behind and continue her life together with Ran. And leave Ai and the Detective Boys behind.

The thought had sadden her quite a bit, but not as much as seeing Kudo with that depressed look of never being able to return to her previous life again. So, Ai finally decided to tell her about the new breakthrough.

"Haibara? What do you want?" Her voice was like silk to Ai's ears. She would miss the childish, yet mature tone.

Ai quickly shook the thought away. She said in her stoical, teasing voice, "Hmm? Nothing much. I just thought you would like to know that I've found a cure to the APTX 4869."

"Eh!?" Ai smirked at Kudo's reaction, "R-Really? I'll be right there!" And Kudo hung up without a second thought.

Ai sighed and smiled softly. "What? I don't even get a 'thank you?'"

"What was that, Ai-kun?" Agasa asked as he walked into the living room.

"Ah, nothing. Can you prepare something to eat? Kudo-chan's coming over to talk about then new antidote."

Agasa stood there surprised. "You made another prototype antidote?"

Ai shook her head. She put her phone down and walked into the basement. "It's not a prototype. It's the real cure." She called to Agasa.

"Real cure? You made permanent cure?" Agasa called back.

Ai returned from the basement with a pill. She placed it on the table and sat down, facing it. "Maybe," Ai responded, " thought maybe not. So far, the results have been positive."

Agasa nodded at the eightteen year old girl with the appearance of a grade schooler before him. He was thoroughly impressed with her. There was one thing that was bothering him, though. "Ai-kun, the antidote is safe, right?"

"Safe? Well, it's the 'safest' I've made. But still, every antidote has its risks." Ai shook her head. "I doubt anything bad will happen."

"Ai-"

"Hakase! I'm coming in!" There was that pretty voice again. She had already made it to Agasa's, showing that she was extremely excited to turn back into Shinichi.

The front door opened, and Kudo stood there with her highschool uniform in hand. A big smirk was on her face. She had deliberately taken out her pigtails, but oddly enough kept her glasses on.

"You came fast." Ai commented.

Kudo nodded sitting down with Ai. "I used the *skateboard to get here and I quickly went to my room and got my clothes."

Ai paused. "Kudo-chan, you don't want to change back now, do you?" Ai thought that they would talk it over today and actually take the pill later in the week. Kudo still needed to say goodbye to the Detective Boys, Ran, and a number if other people. As Conan, of course.

But she just shook her head. "I need to change tonight." She then ducked her head down hiding a faint blush. "I-It's Ran's **birthday tomorrow... I promised myself and her that I would somehow get Shinichi there for her."

Ai scoffed. She really was an idiot, wasn't she? "What would you have done if I hadn't made up another antidote?"

"I would've figured out something." Kudo was impulsive as ever. And that just made Ai face palm mentally and worried relentlessly. One day, Kudo's quick nature and curiousity will lead her into trouble.

"Are you sure about this, Shinichi?" Agasa asked with a concerned tone.

Kudo nodded. "I'll make it up to the Detective Boys after I turn back." She promised. "Can I have the antidote now?"

She held out her hand. Haibara frowned,but gave her the pill nonetheless. "Did you at least think this through, Kudo-chan?"

She looked Ai right in the eyes, oceanic gaze as sharp as ever. "Nope."

And she swallowed the pill.

Seconds passed. Then a minute. Then a few minutes. Shinichi sighed. "Are you sure this was- Gah!"

She was cut off as a sharp pain traveled up her chest. She gasped, taking a big intake of air before another unbearable pain shot through her entire body. It hurt. Much more than usual. She began to lose her composure and fall off the couch.

Agasa quickly swooped in and caught her. "Take her to the bathroom." Haibara commanded. Agasa nodded as Shinichi writhed in his arms.

The trip was agonizing for Shinichi. Every little motion cause terrible aches. She groaned, pain eating away at her.

Once the trio made it to the bathroom, Shinichi was set carefully onto the floor. Agasa then was abruptly kicked out. Shinichi was happy for that. He might've been close enough to be considered family, but that didn't mean she wanted him to see her like this. Or the aftermath.

Haibara slowly started to strip Shinichi from her elementary school clothes. Her ribbon, watch, glasses, and power shoes were set in the corner, away from the simple blue blazer, black skirt, white undershirt, etc. Then, Haibara stood up and said, "Don't die." as she left Shinichi alone.

Despite telling her not to die, Shinichi couldn't help but think that was a good option. The pain clouded her thoughts, as she could barely tell what was right or wrong, smart or idiotic. All she wanted was for the burning stings to leave her.

She wheezed, all energy taken. Please, she prayed, let it be over. Her body began steaming.

Convulsions started. Daggers began boring into her heart. Her bones were melting. Make it stop. Stop it. End me. Kill me.

More sharp pains came in patterns, all attacking her heart area. Kill me. Kill me. Kill me.

Then, all at once, the terrible pain ceased. Shinichi breathed in and out, collecting her thoughts. Was it over?

Just as she thought that, a heavy weight stomped down crushing her, stabbing her, burning her. She let out a in humane scream. Squirming like a dying worm, Shinichi began to glow. Her body became bigger. She was maturing. Her high-pitched shrieks turned into more deeper screams.

The heavy pain was lifted, but the burning sensation didn't stop. Shinichi curled her now teenage body into a ball, and sobbed from the lingering pain. She felt shameful as she ran through her thoughts. She wanted to end her life from the pain.

Shinichi shivered. Was dying an better option if that horrific spasm continued? Would it be stupid to end the painright there, then suffer through it. Shinichi shook her head. No, of course death is a terrible option. People needed her, and she wouldn't let them down due to some hardships. She made it through. She'll always make it through.

Shinichi slowly stood up, wobbly and weakly. She breathed, always remembered to breathe. Seizing her school uniform, she walked to the wall and leaned against it for support. Come on, Shinichi. You can do it, she cheered herself on.

She began to put her undergarments on. Then her bra, followed by her shirt. She was on a roll so far. Tie next. Then blazer. She struggled as she slipped her legs through the skirt, for they were still extremely stiff.

She moaned in relief as she finished. Wanting to see the effects of the antidote, Shinichi made her way to the mirror. She was a mess. Her hair was messy, still holding her odd cowlick. She was incredibly thin and pale. She had dark rings under her eyes, but were those really that new?

Her uniform was a mess. Some of the buttons were in the wrong holes and her tie was not tied on correctly. Shinichi sighed and began fixing her broken image. She felt better than before since all of the pain was gone. Her stomach pained with hunger, though after that episode, she could deal with it.

After examining and fixing herself the best she could, Shinichi grabbed her watch (for it was the only thing from her elementary gadgets that fit her) and exited the bathroom. She quickly checked the watch. It was half past eleven. she was in there for nearly thirty minutes. It felt much slower than that, but Shinichi wasn't going to question it.

She entered the living room the be greeted by the beautiful smell of food. Curry rice. Not her ***favorite, but it still smelled delicious. Agasa set it down on the table. Shinichi sat down and devoured the dish. Agasa chuckled at that. He's never seen the girl eat so readily.

"So, how'd it go?" Haibara asked, not even looking up from the book she was reading.

Still eating the scraps, Shinichi replied, "Terrible."

Haibara raised an eyebrow, but still refused to act like she cared. "Oh? Do tell."

"Painful, burning. The usual, only this time it was ten times worse."

"You didn't die so I assume it's a sucess, right?"

"Well," Shinichi greedily gulped down a glass of water, "I would think so." She began picking every grain of rice from the dish.

"We called the Mouri's," Agasa cut in, "and told them that Conan's parents were here to surprise her and take her home. We also said Conan had to leave right away or she would miss the flight and she was sorry she couldn't say goodbye."

Shinichi paused. "What did she say?"

"She was upset, but happy for Conan." Haibara replied.

"I see." Shinichi looked down at her watch again. 11:39. "Hakase. There's one more person I have to say a proper goodbye to."

"Who's that?"

"Can you possibly drive me to Ekoda?"

*Bah, it's nearly 11 at night, so let's pretend that the skateboard doesn't run on solar power/shot
