Grace feelings

I know Grace is upset that her father cheated on her mom and had another baby outside their marriage but she shouldn't take it out on her brother. She should get to know him and accept him as her brother. It wasn't his fault that he was born and wasn't brought up until he became a teenager. This is a part of growing up and Grace needs to stop acting like a child. Those days are over and now it is time for her to act like a young adult.
