I forgot about Peter Benton! I used to feel like at Peter's core was this deep, deep fear of being helpless and it drove him to be the ogre in those first seasons. I feel like Dr. Park is just driven by this need to be admired and that need creates the opposite result in his colleagues. Considering that so many variations of the "brilliant but flawed" archetype were necessary for this, I give Dr. Gupta kudos and I wonder if these are just combinations of people he has worked with in the past.
What I really want to know is this: Where did he find the time to write a novel?
