Indiana Jones ended with him riding off with the sunset with pop after discovering the holy grail. Indy does NOT have an illegitimate son named “Mutt” and did not survive being nuked by an a-bomb by hiding in a fridge, or meet space aliens. All of that is bad fan fiction that Short Round dreamed up one day. END OF STORY!
That last film was just a bad dream after too much chili for supper. He’ll wake up in the 1970’s saving relics in a war zone.
