Is Marions bearing of a son compatible with the time periods of Indys previous films?
Mutt was probably conceived in 1936 at the end of Raiders of the Lost Ark, meaning that he was born in 1937, making him 19 or 20 years old in The Crystal Skull. Marion and Indy might have stayed together for a few years, and Mutt could have been born as late as the early 1940s (making him as young as 15 or 16), given that Indy introduced Marion to Mutt’s future stepfather, who was a RAF pilot killed in WWII shortly after they were married. There is a scene in Crystal Skull in which Marion and Indiana argue over Mutt on issues such as fatherly absence, paternity and step-parenthood. It is likely Marion’s pregnancy was unplanned, and she discovered her pregnancy well after Indiana’s departure, typical of Indy’s personality as an adventurous yet emotionally distant person.
