In the book To Kill a Mockingbird did Jem Dill or Scout change or grow?

they all change and grow somewhat. Dill becomes more mature from the Tom Robinson trial, and doesnt instigate as much trouble as before. Scout goes from a kid to a young lady, and learns alot also. Jem grows up and learns to take care and watch out for the others. When Atticus makes him read to Mrs. Dubose, that is part of his maturity too.
