Hailey is an ordinary kid who is very introverted and sort of risk-averse. She doesn't go looking for crazy things to do. In fact, every time she comes up with an idea she wants to do, she just puts it on her list and plans to put it off. And when The Professor arrives in her bedroom, she is very reluctant to talk to her at first, but after hearing she made a to-do list that is the first step to saving the world, she has to try new things, which is something Hailey has a tendency to avoid.
