We learn more about Nancy and why she was a people-pleaser and willing to comply with Keith's controlling. We see some remarkable results with people suffering from Tourette's Syndrome. But we also see the dark side of thinking you can totally control your reactions to everything. If you experience something that in actuality you can't control, it is your fault. The problem with these philosophies that claim to explain everything is that they can't. That doesn't mean they don't have some good insights. But they tend to overextend these in their efforts to create a all-encompassing philosophy. As Nancy says, Keith had lots of ideas and concepts which he wanted to make into a science but he never did. But being a psychopathic narcissist, that didn't matter.
