Carl is the weaker and dumb one of the two. Being the child of Jay and Kitcha, Carl is also spoiled and annoys his brother any chance he gets. When carl was only a month and a half he fell off a big rock and busted his jaw. He's fine now but he has this derpy look every once in a while where his tongue falls out a little bit. He also craves his parents' attention but not as much as Walter and goes along with everything he says.
Now that he is an adult, Kitcha decided to make him a finisher due to his big body but Carl really doesn't like this position. There is so much pressure on him since there are really good chasers, Carl just doesn't like his position and he feels the eyes of his hunting party judge him. Even his own brother seems to not hang out with him as much. Walter and Carl got into a fight about carl being the weigh down of the hunting party and that lead to the hunt to fail since they lost the scent. Kitcha realizes that Carl and Walter are siblings and Walter is a big bully so she decides to work with carl by herself when he's not hunting, due to his jaw injury he has to have physical therapy with woody so that he will be able to do his job better.
