I've always thought of characters like advent calendars. You have Christmas and you have all the little doors over the windows and every day you're allowed to open one more as it gets towards Christmas and you see more and more about what's inside that house.I remember as a kid being fascinated by that and I've always thought of my character as a little bit like that. I like to have secrets and slowly let those secrets out to the audience, sometimes never let them out, but let them see as you open the shutters, open and see a little bit more of a character.
