I already wrote about the Great Leader and her immortality. Another interesting point emerged, if we accept the theory about replacing her with a similar girl/clone: is the current Amelia just a talking doll, used as a cover by a group of politicians, or is she an exact copy of the Leader, created by her most loyal people, so that she could rule the country forever and according to her plan, no matter what? I haven't decided yet which of these is true.
In the past, as an alternative, it could be not a clone, but a similar girl. We are talking about a time about 100 years ago, when cloning technology had not yet developed.
