Hunter was the ringleader when it came to all the mischief around the house. He was very aggressive and rude due to the arguments that his parents have about their marriage. He often argued with his brother and talks back.
During observation he and Rivers were calling each other slurs. The name that he called Rivers was a swear word.
He opened up to Jo that his parents fight a lot and are on the brink of a divorce, which made his dad lose his temper with her.
