We must remember that Chelsea was reared by her parents the same way the Hitler Jugen were trained to be tough when abusing and persecuting Jews. She was trained to be numb to feelings which may have been triggered by hearing the truth about her psychopathic parents, just as Hitler trained youth to be numb to the pain they inflicted on innocent victims.
My goodness, what a damning indictment! I thought I was the pessimist. However, you have to wonder what else could it be like growing up with those two as her primary caregivers.
Their personalities have been imprinted on her soul.
Especially with Chelsea being an only child.
