Seriously guys I have only watched this video like 3 times, as well as prologue, and I need you. Fucking depressed EVERYTIME I watch it. with all the theories about Jin is dead....or he is alive and all the other members killed themselves...DEPRESSED. Anyway I found an interesting theory on a YouTube comment where no one dies! Basically it was about insecurities and overcoming them which is a million times less depressing. Yay for that! Anyway I hope we find out for sure soon!
