He has PTSD from the abuse he faced in the orphanage, getting flashbacks, nightmares and more from the director. He has a low sense of self-worth, and is pretty naïve. He has a fear of being alone, and needs to fight alongside someone. When paralyzed with fear or guilt in battles, he tends to react strongly and believe things at face value, trusting others' judgment above his own and even abandoning his own instincts. He has a strong sense of morality.
