I want to ask about Rum-Wakita-, do you think him know about that Shinichi is alive right now!!?
Yes. I think he knows that Kudo Shinichi is alive. We know after all that Rum is actively investigating Kudo Shinichi, seeing as he was looking into his family's activities through Vermouth (File 1060), meaning that he has some kind of lead/info that is prompting this continued pursuit post-File 1012.
Also, according to my personal theory, Rum is a disguised Iori Muga, so I think that Gosho has already hinted at Rum's awareness of Shinichi being alive, as well as actions to get info on him, through Rum's direct involvement with Shinichi's friends: Heiji, Ran & "Conan" (File 1039-1042).
