This discussion on sexual power and motivation in 'Paris, 1916' has been one of the best I've ever seen on The Raven - I'm sorry I missed it! Thanks tupogirl, TalonCard and Stoo!
The way I see it, Indy (as most all men are) is completely ruled by his c?ck in that episode. He is being unfaithful to his idealised, pure love for Vicky, he even acknowledges this in the episode - yet he holds Mata Hari to a tremendous double standard - he wants to control her, stop her seeing or even looking at other men, create something between the two of them that isn't even there (he's just 'a little boy masquerading as a man'). Remarkable self-delusion at work.
She desires his youth, and he yearns for sex and her experience. That's all their relationship is based on, I think the spy subplot is just a red herring in what is a rather interesting exploration of the way men view (madonna/whore duality), exploit and try to control women. That episode could only be written by a woman, and Carrie did an amazing job.
One of my favourite moments in the entire series is when Indy kisses Mata for the first time - he, in all his deluded romanticism is right into it while her eyes just stare blankly into the distance as the camera pushes in.
Remarkable shot.
