Booth

Military Background: His past as a sniper in the Army Rangers has shaped his life, giving him a strong sense of duty, though he sometimes carries trauma and guilt over the deaths he caused. Beliefs: Unlike Dr. Brennan (who is strictly rational and scientific), Booth is a devout Catholic who believes in destiny and God. Personality: He is a sociable, athletic, protective man with a great sense of humor. He is passionate about ice hockey, wears colorful ties as a good luck charm, and has a notorious phobia of clowns. Relationship with Brennan: His dynamic with Bones is the core of the series. He often affectionately calls her "Bones." While she provides the cold, hard facts and evidence, he provides the intuition, the connection with the suspects, and his understanding of human behavior. Evolution in the Series: He began with little faith in science, preferring interrogations and instinct. Over time, he learns to respect the work of the scientists at the Jeffersonian. He is a very family-oriented man. He has a son named Parker from a previous relationship, and later starts a family with Brennan, with whom he has two children: Christine and Hank.
