Rena is able to play sleeping without letting anybody notice. Since we completely lost the sight of her after few pages of this file, I guess she has already managed to escape. In the mean while, it was decided that Conan will visit the three suspects to gather more information about them. Just before that, he ran into someone called Nakamichi from Soccer Club. Conan asked him if he by any chance had seen Eisuke around. Nakamichi said he had not seen him as he entered the hospital only 4 days ago. But he did saw another guy called Aizawara Eisuke just for the sake of seeing. Anyway, later on, Conan plays pranks with the 3 patients while recording them. When he showed what he had recorded to the FBI, Akai Shuichi seemed like he figured out who was it!

What's bothering me now in this file more than anything else is how Nakamichi story is related to the main story?
