Harry Potter was not the boy-who-lived and therefore he was not the favored child of his parents. No, his twin brother Nathan Potter was, and Nathan was easily loved by all, including by the supposedly emotionless Harry Potter himself.
Harry had no time for jealousy—especially not of the brother whom he loved dearly. He barely had time to even enjoy his childhood as heir to an ancient and most noble house.
Under the guidance of cold and strict tutors Harry has grown to be a rather emotionally detached young man. However, perhaps his friends could help him learn what it means to have friends that aren’t his brother. And maybe, just maybe, guidance from professor Snape, and upperclassmen could help Harry become the empathetic Healer that he did not know he could be.
That is if he can learn to navigate and cope with his visions as a seer and not fall victim to Voldemort's ever growing obsession with him that may very well lead him to insanity.
