I'm surprised how utterly easy it is to answer every single question for some of my characters, and how hard it is for others. Although I guess I shouldn't be: Martin actually Lives In My Head, Alix has been around for months, and Dariel's brand new.
If anyone's interested in my answers to any of the questions for any of my characters, feel free to do what that poster suggested and leave a comment with the question number/s and the character name.
