But they love an audience only because and while it provides them with narcissistic supply. Narcissists are terrified of introspection. Not intellectualization or rationalization or simple application of their intelligence - this would not constitute introspection. Proper introspection must include an emotional element, an insight and the ability to emotionally integrate the insight so that it affects behavior. Not in my book.
Narcissists do engage in real introspection following a life crisis, though.
They attend therapy at such time. A single seductive behavior is no proof of the HPD pudding. I think these distinctions are pretty artificial and this is why we always have multiple diagnoses. I think that the diagnostic distinctions between the Cluster B disorders are pretty artificial. But I think that they all lie on a continuum.
