One of my steps in revising the already partly revised first draft is to catch all the hints and suggestions for ideas to develop that linger in the text. These usually are ideas that could have been developed and taken the story in a different direction, or hints for clues to be planted or red herrings to be dragged through the next twenty scenes that were never used. They have all been rejected if not consciously then de facto. I catch them as I read through, and usually don't think about them again. In any story the options are many before we begin writing, but with each scene they are narrowed.
In my current WIP, however, I've taken them more seriously as astute suggestions from my unconscious, and not to be ignored. As a result of thinking about them harder, I've solved some problems that I was lazily going to just read past (until the final draft, of course, one of my bad habits). Ginny Means, a social worker whose caseload focuses on teenage girls in foster homes, has already appeared in two short stories in Alfred Hitchcock Mystery Magazine, with a third in the pipeline. The one hint I grappled with the hardest is the idea of giving Ginny a rescue dog.
In my current WIP I thought the idea of a dog seemed too cliched, since the main character was a single woman who worked, so when I scribbled the line in the first few chapters that Ginny fostered dogs occasionally, I thought I'd just leave it like that. There wasn't really any reason to develop this, so I let it just sit there while I focused on the plot and other characters.
As I kept going I had the usual plot holes to fill, motivations to figure out, and details about her life to clarify. In one instance the presence of a dog could be a crucial clue, and I thought about giving her one of her own. But that posed other issues. She needed to be someone who could roam late into the night without worrying about a dog in the back seat barking loudly at shadows or others in a passing car or walking along on a leash on the sidewalk. But Ginny also had to be seen as compassion outside of her work as well. The idea of the fostered dog reappeared, and once I began to look at this more seriously, I could see all sorts of possibilities for her character as well as another pivotal figure.
I was slightly worried that I was creating another character who had to be seen in part as a villain who had some good qualities. He felt like a cliche and I wasn't sure how to deal with this. I didn't want it to be easy for the reader to dislike him, so somehow he had to be shown to be a decent guy. He got a dog, and Ginny was sympathetic. The foster dog was in.
When I talk about writing as a process of discovery I'm usually thinking about the personalities and quirks of specific figures in the story, their appearance and family relationships. I'm not thinking about dogs determining clues and character, but that's what happened in this WIP. Giving Ginny a foster dog to care for occasionally doesn't change other aspects of her life given in previously published short stories, and remains a feature I can use or not depending on the plot. Those hints and suggestions I usually eliminate have turned out to be important sign posts in this WIP and I'm reading them more carefully now.
