Early on in the game, “Hope is close to his mother Nora, confiding in her and relying on her for protection,”, and does the same with he’s around Lightning.
a boy’s decisive psychosexual experience is the Oedipus complex—his son–father competition for possession of mother.
And while Hope is very close to his mother, he’s had a distant relationship with his father ever since he became a teenager.
Psychosexual infantilism—Despite mother being the parent who primarily gratifies the child’s desires, the child begins forming a discrete sexual identity—”boy”, “girl”—that alters the dynamics of the parent and child relationship; the parents become objects of infantile libidinal energy.
Hope and Nora went on “dates” together. Not those that would lead to an intimate encounter, but just a friendly mother-son vacation. The mother did not think of the son this way, and I’m sure that Hope only subconsciously felt like this.
Hope seemed almost as over-protective of her as she was him. Hatred of his father to his mother might be a subtle hint of unhealthy jealousy. In devaluing his father, he overvalues his mother. But in doing so, he took the relationship for granted.
Nora’s death was so shocking to Hope become of his closeness to her. She was in a sense his best friend, and possibly the standard for all women in his life.
Psycho-logic defense—In both sexes, defense mechanisms provide transitory resolutions of the conflict between the drives of the id and the drives of the ego. The first defense mechanism is repression, the blocking of memories, emotional impulses, and ideas from the conscious mind; yet its action does not resolve the id–ego conflict. The second defense mechanism is identification, in which the boy or girl child adapts by incorporating, into his or her (super)ego, the personality characteristics of the same-sex parent.
We can see just how much Hope repressed his feelings for his mother, by projecting them onto Lightning. Hope also lost his mother, and was looking for some guidance.
All of his guidance came from his mother. Once he decided to stay by Lightning’s side, he followed her around like a baby duckling.
With Lightning, he was probably able to let his guard down around her. He could show some attraction towards her, as he knows she’s not related to him.
He desires to become stronger, probably in order to protect the mother he couldn’t, as she died protecting him.
Later on, Hope takes his father’s calm and collected persona. By acting more like his father, Hope probably reasons that this is what his mother would have wanted from him.
Dénouement—Unresolved son–father competition for the psycho-sexual possession of the mother might result in a phallic stage fixation that leads to the boy becoming an aggressive, over-ambitious, and vain man.
Hope blames his mother’s untimely death on Snow, and it culminates into murderous fantasies. Thankful, he’s able to resolve his frustrations before he acts on them.
