So halfway through I forgot where I was going with it so I began making stuff up and I really just gave up on keeping people in character too. But yeah.
And I'm inconsistent with using character first/last name in narration but it's how I think of them in my head...sorry.
Here's how the detective boys found out.
Really it was Haibara's fault, she forgot about the children coming over and she also forgot to lock the door. So the kids walked in on Conan popping an antidote into his mouth.
They first thought that Conan was sick, which he quickly denied, but the antidote was designed to be a fast acting one, which was rather unfortunate and unlucky because fo the situation and Conan was quickly gasping in pain as Haibara tried to herd the children out of the room and house.
But three concerned and freaking out kids weren't the easiest for someone the same size and stature to wrangle, and Agasa wasn't in the house to help. Quite a series of unfortunate circumstances. At least their view was mostly cover be the sofa so they didn't physically see Conan grow. But when Shinichi sat up groaning from behind the couch wrapped in a blanket the kids quickly made a connection. Although their first reaction was slightly amusing.
"Ah! You're Kudou Shinichi!" Genta had pointed out the obvious.
Mitsuhiko had followed up, "Why are you here?"
Ayumi asked the relevant question, "Where's Conan-kun?"
Shinichi looked a little overwhelmed and disoriented for a second before it clicked and he let out a quiet groan.
"No," He had murmured flatly, reflecting Haibara's current thoughts.
"What do you plan to do, Kudou-kun?" Haibara asked eyeing the teenager as she released the children and walked towards Shinichi to check his symptoms.
Shinichi flopped back onto the sofa and the kids crowded around him. He groaned again in exasperation.
"I don't know, Haibara, what do you say?"
"Conan-kun?" Ayumi called and glanced around the sofa to no avail. She only found Conan's glasses.
Haibara had calmed the slowly panicking girl by saying, "You won't find him here. He's sitting on the sofa."
Three pairs of eyes turned to the teenager on the sofa with his hands covering his face. "Haibara!"
"What do you mean Ai-chan?" Ayumi had asked. Shinichi cast a glare at the other shrunken teen before vaulting of the couch to get his clothes. All three authentic children seemed very confused but neither Shinichi or Haibara provided more.
But children's minds weren't exactly bound by the laws of physics and logic. So having them come to the correct conclusion didn't take long.
"Are-are you saying?" Mitsuhiko began, slowly turning to Haibara to see a slight smirk.
"Who knows? What am I saying?" The girl cryptically replied turning to type at her computer. Shinichi soon appeared again dressed in his signature blue Teitan school outfit.
"You guys are still here?" Shinichi asked, "Why are you guys here in the first place?"
Mitsuhiko offered the answer, "Well, we heard from Conan that Heiji-san was coming today and-"
"HOLY SH-" "Language, Kudou-kun." "HATTORI IS COMING!"
"Yo! Kudou!" A dark shinned Osakan waltzed into the room with acute timing.
Haibara sighed, "Speak of the devil."
Heiji paused at the doorway. The detective boys also paused. For the third time that day Shinichi let out a groaned and slumped against the wall.
"Kudou?" Heiji asked, concerned. Shinichi raised a hand as greeting to his friend without lifting his head from the wall.
"My head hurts from trying to figure out how to clean up this problem," The tired teen muttered. Haibara looked up.
"Do you actually have a headache? Is it from the antidote?"
"No, no, I'm fine."
Mitsuhiko was thinking. He already has an idea of what's going on. Conan had mentioned Heiji was coming over, and that Heiji was going to meet with him. But Heiji's first thing was to say 'Kudou' and address Shinichi, who wasn't there a few minutes prior and Mitushiko was relatively sure that Heiji didn't come to see Shinichi. Then Haibara had mentioned 'antidote'. It made as much sense as it didn't.
"Were you poisoned?" The words blurt from his mouth before he could stop it.
Every occupant of the room went silent.
Heiji's comment broke the silence, "Wow, ya taught 'em well."
Mitsuhiko continued on the train of thought following back to that time he had a similar idea with Haibara being a child star. "You were poisoned. Being a famous detective caused something to target you. But instead of dying you..." He didn't say it but everyone knew what he was going to say. "You know. But because whatever dangerous thing was targeting you supposed you were dead, you went into hiding. You posed as Edogawa Conan to help lure out this criminal organization...is Haibara actually a spy?" (Refer to OVA 11)
The older occupants of the room stared blankly at Mitsuhiko for his spot on deduction.
"Oi, Hattori, am I teaching them too well?"
"Possibly."
"No wonder why Conan was so good at soccer!" Genta exclaimed. Everyone sweatdropped.
Shinichi walked up to the freckled boy and crouched to his height, "Amazing deduction, Mitsuhiko. Sonotoori desu. You're exactly correct. But don't pry further or you might be in danger, okay?" Shinichi then turned to address the other detective boys.
"I don't want any of you children caught in this dangerous stuff. You understand right?"
"HAI!" They chorused.
"Of course, you also have the important job of keeping my secret and helping me in the less dangerous stuff, as a bargain for this."
"Ne, Shinichi-oniisan?" Ayumi said shyly.
"Yes?" The teen detective turned to the girl.
"Arigato for trusting us!" The girl chirped and pecked the teen on the cheek. (Refer Ep. 109) She giggled and smiled at him.
"Ah? Ayumi-chan!?" Shinichi sputtered, confused by being pecked by a kid. Heiji was laughing his guts out behind him.
Genta and Mitsuhiko turned to face each other. "Even as Shinichi..." Genta started.
"Ayumi-chan has kissed him again," Mitsuhiko finished.
"Run, Kudou, run!" Hattori chortled behind Shinichi as said person scrambled to get off the ground before the two jealous boys could finish plotting his murder.
The kid had turned simultaneously with similar dark expression, then both began running after the teen with Mitsuhiko threateningly calling, "Conan-kun!"
Which at that he paused and slapped his hands over his mouth. "It's just slipped, I-"
"It's okay-" Shinichi offered, which allowed Genta to attach to his leg and the teen promptly tumbled to the floor. "Oof."
Heiji probably had the best laugh of his life. That was until the antidote wore off and Conan rallied the detective boys against Heiji. (Maybe KID got involved too because there was green hair dye in his shampoo when he got home.)
Haha, I'm sorry, that was really random. I've been bored but I'm too lazy to properly think of logical stuff.
But yeah, I thought it would be cute. XD
