Dr. Stephen Kellerman: Patient interview 9. Dr. Crane continues to evade questions. I believe he is quite sane. Just evil. He takes no interest in the people he has hurt. His research appears to be the only motivating factor in his life. What is it about fear that drives your obsession?
Scarecrow: Fear drives everything, Stephen. Everything. Your life is governed by fear. Every decision you make is a product of that fear.
Dr. Stephen Kellerman: Don't be ridiculous.
Scarecrow: You married your wife... Margaret, isn't it? ...because you were scared of dying alone. You have children because you are scared of leaving nothing behind that really matters. You go to the doctors because you're scared of dying. Do I need to go on?
