I have a "theory".... What if 704 is in reality the so said "first human with unbelievable spiritual power" that Geumsum(?) Mentioned. If that's right, he is somewhat Sam's relative and died because of so said condition. That would explain Geumsum's (?) surprise when he "first" saw 704 as a reaper. Because he already knew him and had a story with him. (⊙…⊙ )
