To be honest, Senichi has no idea how Vermouth discovered Haibara's traces in the original story.
In the original story, there was only a sudden scene where Vermouth discovered Haibara, without revealing how exactly she found out.
However, a somewhat reliable speculation is that Vermouth saw Haibara and recognized her afterward.
Just like Pisco, who was shot in the head because of Senichi's appearance, it's highly possible that Vermouth had seen Haibara when she was younger, so upon seeing her again, Vermouth immediately recognized her and realized she had shrunk.
After all, Vermouth, being dubbed as the "immortal witch," had lived long enough to see a younger Haibara, so it's reasonable.
On the other hand, Vermouth was particularly interested in Conan and Ran due to her connection with.
And with Conan living in Ran's house and Haibara being in the same class as Conan, their daily interactions could have been another point of discovery.
Overall, the likelihood of Haibara being discovered was quite high.
However, because Haibara and Conan were in similar predicaments, it was actually somewhat safer.
As long as Vermouth cared about her "son" Conan's safety, even if she wanted to kill Haibara, she could only do it herself and couldn't leak the information to the organization.
After all, if the information about Haibara shrinking was known to Gin, it would essentially mean exposing Conan's identity, and Gin would definitely choose to silence him.
In other words, as long as the story continued along its original trajectory, there would be no problem.
As for Akemi Miyano's identity, it must be kept strictly confidential, absolutely cannot be leaked. Once discovered, it might trigger pursuit, and even involve the "innocent" Haibara and Professor Agasa.
Fortunately, Akemi Miyano's identity could withstand investigation. After all, it was based on the real identity of Narumi Asai. Even if someone investigated Asai... no, Narumi Sakurada, on the island, there would be no loopholes.
Although the husband, Saburo Sakurada, was overseas, to maintain the facade, a sum of money was still transferred to Narumi Sakurada's account every month. Of course, Saburo Sakurada couldn't transfer the money himself, so it was all orchestrated.
Occasionally, there were also some souvenirs sent over from overseas in the name of Sakurada, and occasionally some return gifts from Tokyo, perfectly portraying the image of a loving couple separated by distance.
As long as an investigation was conducted, the identity of "Narumi Sakurada" would stand up to scrutiny.
Just a female doctor who came from Tsukikage Island, married her husband shortly after, and due to her husband's work, he went overseas, leaving her alone, so she took on a job as a full-time caregiver for the elderly.
A completely ordinary person, without any suspicious traits.
Of course, being around the target naturally raises suspicions.
But Senichi already has a plan for this.
"Alright, let's not chat further for now. Just be cautious."
ignoring Haibara's resentful gaze, Senichi looked at Miyano Akemi and explained: "The arrival of Shuichi Akai itself indicates something.
The Black Organization probably hasn't given up on searching for the two of you. I have a feeling something is brewing."
Senichi's expression turned serious as he continued, "Better safe than sorry. I just hope my instincts are wrong.
In any case, be careful during this time, pay attention to your conversations, and always be aware of the possibility of bugs.
If you find one, don't rush to destroy it. Contact me immediately and carry on with your normal conversation. Don't let the eavesdropper know you've detected the bug."
Upon hearing Senichi's instructions, everyone's expression turned serious,and Conan also frowned and said: "We need a tight plan to ensure our identities aren't compromised..."
"No need, I've already devised a thorough plan," Senichi shook his head and smiled at Conan, "You just need to cooperate with my plan when the time comes."
Conan's face suddenly darkened upon hearing Senichi's words, looking exactly like Haibara who was stabbed in the heart before.
Damn it!!
He's treating me as a tool again, not even consulting me about the plan, and when did he even set up the plan, you bastard!!
We've just encountered this situation, why are you so proficient already?!
Facing Conan's resentful gaze, Senichi smiled faintly and didn't say much.
After all, the plan was already set long ago, with numerous contingencies prepared. How could your makeshift plan with so many loopholes compare to mine?
"Can you at least tell us the plan?" Conan looked at Senichi with a probing gaze and a hint of defiance, "Maybe I can help improve it. After all, there's strength in numbers."
"Well, I can tell you, but honestly, there's nothing you can do to help with this plan," Senichi said with a slight smile, delivering a heart-piercing blow.
Conan, who had been scowling, was initially somewhat unconvinced, but after hearing Senichi's plan, he became even more disheartened.
Because this plan will help Akemi Miyano protect her identity...
I really can't contribute anything!
Damn it!!
Being able to fight is great! How awesome it is to be able to disguise yourself! ! Even his skills are much better than mine! !
Upon hearing that all the skills needed for this plan were beyond his capabilities, Conan fell into a deeper sense of despair.
Of course, what Senichi told Conan and the others was just a rough plan. It was impossible to disclose the specific countermeasures.
After all, that was a plan Senichi had devised specifically for the circumstances that would unfold later. Revealing it now would only cause trouble.
But even with just a rough plan, it left everyone deeply worried.
"Don't worry, there won't be any security issues," Senichi reassured them with a smile, "If I can't win, I can still run."
"I just hope the situation won't turn that way," Haibara said with a gloomy expression, "Then you won't have to take risks."
"Alright, you guys don't need to worry. After all, this plan is just a contingency for the worst-case scenario."
Feeling the heavy atmosphere around him, Senichi smiled and said, "Maybe we won't even need this plan at all."
However, these were just words of comfort from Senichi. He himself didn't hold much hope for it.
The plot was bound to unfold, that was for sure, especially since the next phase involved the first direct confrontation with the Black Organization.
But as for worrying about safety... Senichi wasn't worried.
After all, he was a man who followed the guidance of his heart. How could he put himself in jeopardy?
Besides, Senichi had meticulously devised a plan tailored to the situation, coupled with two capable teammates. Safety was definitely not a concern.
