The dark conversation about Sherry
The start of the chapter appears Gin's Porsche. Gin is having a conversation with Vermouth who talks about the Belltree Express which Gin wonders why Sherry would ever go in such a conspicuous ridiculous train. Vermouth explains to Gin that all the passenger cars on that train have private rooms, which means if she would escape the Kantō region without being noticed, that would be the best option to escape. Gin still cannot believe that Sherry was at the mountains of the Gunma Prefecture. Bourbon also had the same opinion about that Sherry was around somewhere in the Gunma Prefecture.
Vermouth explains further to Gin that if Sherry boards that train, as far as hunting grounds go, won't that be the most suitable. Gin agrees by what Vermouth have said. Vermouth tells Gin why she'd leaked the information to him. Gin response that he is happy to hear the name Sherry after a long while which he thought that she was having mercy for her female colleague. Vermouth response telling Gin for what he is taking her for and ends the conversation. She then remembers what she had told Conan before by giving up Sherry for him. Vermouth then thinks that she isn't the one who is going to hunt Sherry, but Bourbon which she is the one who cannot be allowed to live in this world. She then thinks by that Conan must not think badly about her.

Haibara gives Conan the blame, which Conan told her that she had to stayed home and rested until it went over. Sonoko then appears telling them that they should thank the Suzuki Conglomerate for reserving them a special seat, but unlike them, Sonoko and Ran are sitting in a luxurious first class cabin, which Ran asks Sonoko that it may be the place where Kaitō Kid has announced his next heist next month. Sonoko response saying that she will place a love letter for Kid to notice it, but Ran doubts if Kid has the time to steal a love letter, and evenly tells her that Makoto might be angry if she does something like that. Sera then appears telling that she is only interested in the deduction quizzes they hold each year, which Sonoko asks her why she came here.
