Jody is often fearful of and intimidated by his father. He has a quiet, mild personality and is usually very curious about his surroundings. He is very easy to teach and eager to learn, and he spends a lot of time with the ranchhand, Billy Buck, on his family's ranch in order to learn the things that he knows.
Jody does appear to have a mean streak in that he oftentimes takes out his aggression on animals nearby; this is not entirely unexpected--after all, he is just a kid and does not always know how to properly vent his feelings.
Jody is also very sensitive. When his horse dies, when Gitano leaves the ranch w/out warning and when he learns how sad his father makes his grandfather, Jody responds with tender concern and passion.
