I just made an account for asking this question. I'm from germany, so please excuse my english.
My question is about this article: http://www.detectiveconanworld.com/wiki/List_of_characters_who_know_Ai_Haibara%27s_identity
My question: How do we know that Shuichi Akai knows the identity of Ai Haibara? Or rather how do we know that "he figured it out at some point near the end of the Vermouth arc."? (see below in the quote from this website)
This doesn't make any sense to me, because if he would knew that Ai Haibara is Sherry (at some point near the end of the Vermouth arc), than he would know automatically that there is something that can change an adult to a kid. Logically he would know instantly, that Conan is Shinichi Kudo, because he suspected him for a long time already.So, the thing is, that he knows that Conan = Shinichi, but this is something he's finding out later as Subaru Okiya.
If we're following the premise that he knew that Ai = Sherry from the point of the Vermouth arc, than he would knew that Conan = Shinichi, too.
That means that either the List of characters who know Ai Haibara's identity is wrong (which I think is the correct answer, because I didn't find a 100% clue for Shuichi knowing Ai's identity), or the List of characters who know Conan Edogawa's identity is wrong, because Shuichi would know Conan's identity at some point of the Vermouth arc, too.
