What is actually happening is that the back is presenting without masking who they are through the shell. Meanwhile, the shell alters may decide to coalesce, for greater strength, and may decide to change jobs. Each system will decide what is best for them. Survivors of Illuminati programming will always have some type of hierarchy inside. This is because the cult itself is very hierarchical, and puts this hierarchy inside the person.
Trainers are also very hierarchy conscious themselves.
They know that a system without hierarchy and head honchos inside to direct things will be a system in chaos. They will not leave the person s system leaderless inside. Many trainers will put themselves in the person, over the internal programmers or trainers. The survivor may be horrified to find a representative of one of their worst perpetrators inside, but this was a survival mechanism. A tenet of human behavior is that often people will punish someone less who mimics them.
