The Last of the high kings

The main character in the book is J.J. He's a static character so far as i have read in the book. He's a brother to his younger children and takes care of them. All he does is help out with everything but its not suppose to be his job. His character so far in the book has stayed the same and hasn't changed. He's a flat character for me because I haven't learned anything about him so far. I've learned a few things about the other characters but not him specifically.As I go on reading I think he's going to turn into a dynamic or round character because I'll have more information on him and have a clear understanding of his character.
