they will serve a purpose, we see the evolution of the lost symbol guy and the iron fist girl into probably the so-called "ai" and "the grandmother of julliette?".

In one of the older episodes, the Gloria Hildebrandt character is part of a group that remembers "the old world" and got a forced treatment of the "vitamin D+" amnesia drugs.
