I mean, if you’re a Nazi, what is the ultimate treasure if not the control over time itself to change the course of your own terrible history?
Wonder if Indiana will be tempted at a certain point with the prospect of going back/changing and fixing his past mistakes with this macguffin, but then realizes that a life well lived is a life well lived, no matter how many mistakes he’s made in his life and ultimately wouldn’t change anything. I could almost see a “The Last Crusade”-esque scene of him talking to his younger self, confronted with a choice, then refusing it, kind of like him with the Knight.
There’s this almost ethereal, slightly dangerous and mysterious wonder from a lot of the other supernatural encounters in the series that I think could be applied to the time travel aspect in this film. Wonder if time travel will be treated the same as a lot of the previous macguffins in this franchise. This mysterious, unknowable thing that the enemy tries to utilize and control, but it ends up backfiring on them for their recklessness, lack of respect for and misuse of the the natural order things. Used as a plot mechanic for Indiana’s story, maybe explained a bit, but not explored much more beyond that, just like the Holy Grail, the Ark and the Shankara stones.
