Ever have a character who's impossible to nail down? I have a minor character right now who is giving me fits. Her voice isn't the problem. I just can't figure out what her "thing" is. Her defining characteristic. Her deepest need. Right now, she feels kind of scattered. I know all these different aspects of her personality, but they don't feel cohesive yet.
I think J.K. Rowling is a master at this. Name any Harry Potter character, I can probably tell you what his or her "thing" is.
Hagrid? Gruff teddy bear. Molly Weasley? Worrywart mom. Fred and George Weasley? Troublemaking jokesters.
Yet, not a single one of her characters, even the most minor, feels one-dimensional.
Yep. I've got a Mary Sue on my hands.
What's a nice, mean tic I could give her?
