"In psychoanalytic terms, having projected his childish rage onto the caricature Dursleys, and retained his innocent goodness, Harry now experiences that rage as capable of spilling outward, imperiling his friends. But does this mean Harry is growing up? Not really. The perspective is still child's-eye. There are no insights that reflect someone on the verge of adulthood. Harry's first date with a female wizard is unbelievably limp, filled with an 8-year-old's conversational maneuvers."
