Huge spoiler alert if you haven't already finished chapter 1:- read at your own risk, YOU WERE WARNED
The student banned from the game and then found dead in his garage... stress and overexertion?? From personal experience when I was younger, I was told a friend of my parents that I knew, had died in his sleep... turned out years later it was a suicide by hanging due to depression, and I was being protected from the darker truth.. I suspect that's what may be revealed in a later chapter...
