Satoshi comes to believe he was the only one who could protect his sister. Despite his best efforts, Satoko still suffers a mental breakdown.
In the Question Arcs there remains uncertainty as to where exactly Satoshi disappeared. According to the TIPS in Meakashi-hen, he was last seen at a Nagoya train station boarding the Shinkansen bound for Tōkyō. However, no solid evidence exists to confirm that rumor, and it is most likely a false tip to justify the expansion of the police's search range. It also conveniently explains away his failure to reappear.
