At first, Jack seems rather cold and distant, not relying on the help of others and claiming to be able to handle things alone. Once someone earns Jack's respect, he'll do anything within his capabilities to earn that person's respect back, and also help them in any way he can .He has his own cactus plant he really likes. He hates Onions very much. He's okay with pets on his ears. He could be a cuddle person when alone.
