This whole process is rather insidious.
I go to turn in, but then an idea strikes me. The extension of a story thread I threw in there, the growth of a throwaway character. Suddenly it's 2am and I'm staring at a computer screen, cursing this story-induced insomnia.
Hell, the problem I had just now was that I introduced a secondary character as an alias of Richard Faraday, but then the story took him somewhere else entirely... now I'm thinking what the opposite number of a Ghost Detective would be, and how interesting it would be to have him thrown into the mix. I just need a name for the role. When I say opposite number of a Ghost Detective, I don't mean "a ghost", because that's too easy. Argh, what to do?
