More thoughts on Indy's friendships..
Some friendships have periods of less than friendly times. Assuming that Sallah is part of Indy 4, do you think that a chilly relationship could occur between he and Indy? Could their long friendship be endangered by pride and distrustfulness? Would such a state of their comradeship work for you as a subplot? Should this be explored at all? Might it add an interesting twist? Would you be for or against something like this between Indy and any of his circle of friends, including his lover (be it Marion, Willie, someone else?), his dad, his child, or even Short Round?
