Okay,Raider's of the Lost Ark took place in 1936, and the Last Crusade did take place in 1938,( My mistake ) but there goe's your idea of bring back Shorty because in the 20 year's or so between the story line of Temple of Doom and Indy IV, 11 year old Short stuff will have turned into 30 year old tall stuff. I think like I said before that bringing Shorty back as member of the archeology team is great, but I also think Indy should have a son (by Marion)
in Indy IV,( you can read some of my thought's on this subject at my other thread. )
