Remus had watched Harry grow from afar. He couldn’t have fought for him, not with his condition. He would have lost, especially after the war. So he had to watch as he was given to the Dursely's, raised second to their son. He was given a quarter of the life he deserves, it barely amounted to the sheer love his parents had for him. He had seen James as a dad, Lily as a mum, and he knew Harry had struck gold. He would have been so loved.
