In the novel I have been writing, I naturally developed my villain's backstory, personality, motives, etc. Somehow, I've made it two thirds through my draft, and I'm realizing my protagonist is very nebulous... even to me. I've spent some time, trying to "get to know her" better, but now I have so much written with what I feel is a pretty two dimensional character. I feel that on some level, she has developed some throughout the story, and that she will continue to develop as her story unfolds, but I do think she needs a stronger sense of self to come across. I am very familiar with her story and what happens TO her, but she, herself, seems very unfamiliar to me, and I'm afraid that is coming across in the form of inconsistencies in her behaviors and reactions. Is this something to worry about when I go back and revise, or should I stop all progress and figure out how to fix this now? Suggestions and ideas are very welcome.
