Jo is Jo, meaning her interests lie far beyond solving the case, organizing her information, or writing a book. What her primary mission is unknown to me and anybody I know.
Part of her passion may be fueled by loneliness, but there is something else. She dug into Duane and DB Cooper in a huge way even when her husband Jim asked her not to. In response, she had to sneak around the guy. Why did she do that? To feel important?
Does she like playing mind games with everyone in Cooper World? Is it an addiction? A rush? Or is someone paying her to do it? Where does she get all of her information? How did she know where Tina was before me and Galen? Why do so many Norjak principals pay her homage?
Jo is one of the mysteries of Norjak.
