But You Almost Knew Him As:
Talk about raping your childhood.
In Raiders of the Lost Ark, we find out that prior to the events of the movie, Indy and Marion Ravenwood (Karen Allen) had an affair that ended when he was 27 and she was about 17. But their relationship took place in the 1920s, when (adjusting for inflation) 17 was like a solid 25 in modern breasts, so it's at least pretty much kosher according to the conventions of the time.
But no possible justification could make Indy anything other than a "sick child molester" if he had boned Marion when she was, say, just 11 years-old. Which is exactly what Lucas and Spielberg originally planned for him.
His winks are signals for help.
