I have an idea for a character for Indy 4. Indy should have a younger sister. She should be sweet but tough. Much like her older brothe an she too would be an archeoligist. And have to work with her brother. She would have the same stubborness and need to be the leader as Indiana, thus creating room for sibling quarrels that would get them in trouble. Instead of Indy having the love interest she would, this could bring out the overprotective older brother in Indiana. Her age would be somewhere between 20-35 what do you think?
