Nadine's mother is very caring, if somewhat overprotective. Catherine lives near Rivet City, and asks you to look for her daughter. Nadine was always a headstrong girl, and the first to bag a live Mirelurk hatchling, but Catherine fears her little mite doesn't have the experience to survive in open wilderness.
"You! Are you going to Point Lookout? I need your help! My daughter stowed away on the Duchess Gambit a few weeks ago, and I've been worried sick ever since. I haven't heard anything from her, but if you're going there, could you look for her? Please, I'll do anything to help!"
"Only that it's where Tobar gets those Punga Fruits he sells off. Must be making a good profit off of them, too. I hear rumors the place is full of swamps and killer plants, but I don't know about all that."
