Following the rotten creator idea. The creation of ESB was close to the creation of Raiders, and at that time Lucas pushed for the implication that in Raiders, Indy had had relations with an underaged Marion.

G — I was thinking that this old guy could have been his mentor. He could have known this little girl when she was just a kid. Had an affair with her when she was eleven.

L — And he was forty-two.

G — He hasn't seen her in twelve years. Now she's twenty-two. It's a real strange relationship.

S — She had better be older than twenty-two.

G — He's thirty-five, and he knew her ten years ago when he was twenty-five and she was only twelve. It would be amusing to make her slightly young at the time.

S — And promiscuous. She came onto him.

G — Fifteen is right on the edge. I know it's an outrageous idea, but it is interesting. Once she's sixteen or seventeen it's not interesting anymore. But if she was fifteen and he was twenty-five and they actually had an affair the last time they met. And she was madly in love with him and he...

S — She has pictures of him.

Lucas had a cavallier attitude to plot devices in the creation of entertainment, this psychiatrist story seems out of character with early 80s Lucas.

Wow, that's REALLY disturbing. First Marion is eleven during the affair, then ten (22 minus 12), then twelve, then finally fifteen...but only because Spielberg made an objection to George's initial suggestions. Good thing he was there to do so--a good example of why George really needs someone who can actually say no to some of his stupider ideas! I realize this was only a story conference, but jeeze...to even suggest some of this stuff is unthinkable for a character you want to have any kind of moral compass.
