What are Kennedy's strengths in the novel, Unbreakable?

Art is one of Kenney's strengths along with her eidetic memory. Kennedy also rejects wearing, as she's against the idea that girls have to look pretty and polished with tons of makeup slapped on and their eyelashes curled. She’s going against the traditional views, which sets up her personality for the reader and the fact that she is going to have more going on than just worrying about running into her ex at the movies.

Kennedy's brain is wired for shapes and symbols and ,as such, it fools the reader into thinking this is going to be her specialty within the group. She is the one who notices the symbol in the journal about the shift, which is a bittersweet thing. For one it shows that she has attention to detail that the others don’t possess, and so this makes her special in a way. At the same time, however, it’s Kennedy that gets them started on the shift as a weapon, which sends them down the path to release Andras. In essence, her abilities with art are about as helpful as they are dangerous.
