So what will become of Mills/Ideas for a sequel??
I'd say that after his much needed 1-3 year "rest" in a psychiatric facility, he gets out to learn that John Doe (out of some type of sympathy/respect/guilt) has left him the remainder of his money. Which Mills then uses to fund his hunt for serial killers. I'd like to also have some appearance of Somerset in maybe helping him physically or just advising him in his investigations.
What are your ideas??
