>>185I'm not sure that's really the case, it depends on what you mean by "the difference between the two sisters". When Ooishi visits Keiichi at the hospital at the end of Watanagashi and explains what happened, he reports that Shion was found dead in the well, and Mion fell from an apartment window. This is actually not wrong, it's consistent with their birth names. The problem is that no one knows Mion and Shion switched places when they were kids, and that the person who had been living as "Mion" is Shion and vice-versa.
