• There's this problem about the Adept Dystopia that Demerzel created (Yes, that is no Utopia). We know that obtaining a Septima has nothing to do with someone's bloodline, and a non-Adept parent can have an Adept daughter or vice versa. (For example, both Dr. Kamizono and his son Copen were ordinary humans but his daughter Mytyl is an Adept), So what happens if a pair of Adepts had a child that was born with no Septima? Was that child killed instantly, or the parents have to purchase a compatible Septima for them?
• We're never shown what happened to the original Sumeragi Seven, or what Zonda did with no way of achieving Eden. It makes one think what Demerzel had planned for them, and if he let them live past normal human lifespans, but it appears that his modus operandi is out with the old, in with the new, and survival of the fittest. So, what did they actually planned for them?
  • The only Sumeragi Seven Adept (bar Zonda) who was still around after Nova's death is Carrera, and Asimov might had been killed him on the way back to earth. As for the Eden Seven, Asimov simply needs to raid them and try to kill everyone there. I think he also extracted Zonda's Septima, hence the illusory Falcon clones Copen fights when he approaches Demerzel.
