Susan Scott, daughter of Willie Scott, professor of Mathematics (emeritus) at Princeton University, described as "the new Einstein", announced that she intends to search for her biological father.
Given that Marion chooses to be a single Mother in 1937 (ish), and then goes out to trap another man, I wonder what she would think about Indy regarding all the other bastards he probably had and how in Crystal Skull she was so quick to give it up again.
I wonder if she wondered if all the other bastards had names relating to dogs as well? Would it be a cool dog's name like 'Indiana' which you wouldn't know had been a dog's name, or something obvious and scrappy like 'Mutt'. What about "Mongrel', "Mongrel Jones Junior'? It actually rolls off the tongue nicely.
