I see it too! What stands out is that they're both fantasists, logic isn't a strong point, at times child-like, they've got a superior air about them in manner and speech.
I'm thinking both charmed/manipulated their parents and others with their good looks and a sweet demeanor they can turn on or off like a switch.
Tortoise's link to the article about narcissistic rage/injury, imo, applies to both of them too.
What about some Asperger's characteristics too?
