Hmm... Not sure if you could get a more satisfying ending for Deter with a reveal (which Christina had asked for) other than to kill him off. I implied that he would be discredited thanks to his narcissism and copious notes. But you all seem to want to see blood... I hope Christina is happy with it and feels she got her money's worth out of it. But if not, PM me. Since it was your story, I'd make an exception and change things if you really want me to...
