Has Detective Conan ever appeared Shinichi jealous of Xiaolan, and what is the title of the play?

Probably not. Shinichi won't do that.

Summary. It's the 400th episode of "Doubtful Xiaolan". Conan only has a mobile phone and a number.

So hide the caller ID when calling Xiaolan. Xiaolan suspects Conan's identity, and Dr. Asasa's mobile phone is the same as his own, so in order to hide his identity, Conan borrowed the doctor's mobile phone, deposited several emails in it in advance and set a password, pretending to be his own mobile phone. Let Xiaolan "decrypt" Dr. Asasa's mobile phone.

On the other hand, Conan prepares a new number as Shinichi's mobile phone number. When the time is right, use Shinichi's number to call Xiaolan**, and then go back to Dr. Asasa's mobile phone. In this way, Shinichi was talking about ** over there (in fact, he was playing a recording), and Conan stood in front of him, which dispelled Xiaolan's doubts about Conan's identity.

And Conan can explain that "there is an email from a girl you like on your phone", which can explain his previous flustered behavior. In fact, during the whole process, Conan did not use his usual number. After that, Conan prepared two mobile phones, one with the number of Shinichi and the other with the number of Conan.

I'm sorry I don't understand, but can you elaborate on that?

Friends who have watched Detective Conan know that Xiaolan has always liked Kudo Shinichi, and since he couldn't contact Kudo Shinichi, he would inquire about him from all aspects. But then there was a child, Conan broke into her life, and let him see the shadow of Kudo Shinichi in Conan's body. So there are many friends who have to ask, when did Xiaolan know that Conan was Kudo Shinichi?

Actually, Lemon feels that Xiaolan must have known that Conan is Kudo Shinichi for a long time, because there are several points that are enough to prove that Xiaolan knows that Conan is a smaller version of Kudo Shinichi. Xiaolan in the cartoon is a very smart girl, and she is very careful, whether it is in observing things or observing characters, it is impossible to say that she did not find Conan's flaws.

In addition, Mori Kogoro and I will be pricked by Conan, and every time I will come back to consciousness unharmed. Thinking about such a thing with normal people's thinking, it is absolutely impossible to have no flaws at all, and it is impossible for Xiaolan to be such a smart and careful girl who has not discovered these.

There is also the fact that Conan has always lived with Xiaolan, whether it is in terms of daily behavior or contact in life, Xiaolan has never doubted that Conan is impossible. I remember that in episode 7, Conan always returned to his true colors intentionally or unintentionally, although he was just a child, but he always treated Xiaolan in the way of Shinichi Kado, and once Xiaolan praised Conan and said: "It's worthy of Shinichi Kudo, I found it so quickly!"

However, Conan may have forgotten his new identity at that time, and directly said to Ran with Shinichi Kado, which is also the first time that Ran has doubted Conan's identity. And in episode 96, Xiaolan is even more sure that Conan is Kudo Shinichi, because Conan's action of taking off his glasses is exactly the same as Kudo Shinichi.
