==Personality==
Jack is a genius at engineering and has vast knowledge about everything related to technology. Despite sharing the same interest for machines and computers, he admits that he greatly relies on his girlfriend Carrie Newton for emotional support and guidance, due to her being more experienced than him. He is naturally devastated by her death, and falls into a deep depression afterwards. Jack turns into a shell of the optimistic tech nerd he once was, becoming quiet and emotionally distant from the rest of the Naval Military. He also becomes irritable and occasionally aggressive, as shown when he snapped at Ooi, whose life Carrie saved at the cost of her own, when she attempted to comfort him. Due to his emotional distress, Jack is often delegated to less dangerous tasks, such as hacking.
Following the events that eventually resulted in his new relationship with Yuudachi's sister Shigure, Jack finally starts to move on from his girlfriend's death and takes a more proactive role in the community, including becoming an intelligence officer for the Naval Military.
