I'm sorry if someone else has already posited this idea.

Her father is quoted as saying he's fascinated by everything to do with Spain but hasn't a drop of Spanish blood, right? And there's a Freudian theory about how young kids develop feelings for their opposite-sex parent. An unconscious sexual desire wish to exclude the parent of the same sex. Usually called the Oedipus complex (for boys) the girl equivalent being called the Electra complex.

Maybe she's always played with this persona - the Spanish Hillary as a way to capture her father's attention. And it got very strange and out of control as an adult. Topped off with a massive dollop of narcissism and a dash of histrionic personality disorder.

She also married a much older man - a father-figure.

Yikes for her. But it feels like an "aha" for me.
