The final chapter is obviously going to be 16th killing all the clones who ever slighted her. That's basically all of them? Only she and 6th will remain, until the experiment is brought to an abrupt and final end because obviously raising a murderer wasn't the goal. The teachers/researchers who were involved in raising them will also be put down... only to be replaced with clones. They too were clones, all along. Start over from chapter 1.
