She is a classic Wodehouse heroine — feisty, pretty, sometimes terrifyingly capable, but absolutely volatile and a little insane (those last two traits — like every other Wodehouse character).
Depending on what type of thriller novel you're writing, some characters may have to have specific traits, such as being insane, or being a spy.
Philo of Alexandria, Josephus and Seneca state that Caligula was insane, but describe this madness as a personality trait that came through experience.
Athletic, Party Animal, Flirty, Hopeless Romantic, Great Kisser, Virtuoso, Snob, Insane, Technophobe, and Schmoozer are totally inappropriate choices for traits for nerds.
An insane capacity for self-publicity proved to be a Currie family trait in 1997 when Edwina Currie's daughter Debbie brought this to the world.
When Jessi becomes a young adult, if you have a choice of traits, do not choose Commitment Issues, Clumsy, Technophobe, Insane, Inappropriate, Mean Spirited, Kleptomaniac, Loser, Slob, or Dislikes Children.
"It's insane, insane, insane, insane," one said cheerfully.
"Insane, insane," he said.
