How Deok-su’s fate was foreshadowed
In episode 7, Deok-su confronts his maker, but he was foretold in episode 2 when he’s being chased by a group of men he owes money to.
He leaps from a bridge into the water to avoid them. During the glass bridge game, he does not consciously decide to do so, and there is no water there to break his fall. Good riddance!
