I got a question, in chapter 817 http://www.mangahere.com/manga/detective_conan/v74/c817/13.html Burbon asking them how they deal with their passwords, Ran wasn't that specific, but Kogoro was very specific and said 5563, why would he tell a password of his PC which contains files of cases. personal files, to a stranger? isn't that a bit suspicious? also because of that Burbon knew that Sherry will be on the train http://www.mangahere.com/manga/detective_conan/v74/c817/14.html
