Oh darling, you know I love this fic! I think there is a difference between being a father and being a godfather, especially to an orphan like yourself. I think you showed marvelously how Harry would rise to the challenge and do justice to the 'position'. Teddy is one lucky boy.
I love the snippets you chose to show the bond between them, not all sunshine and roses-a few rough patches as well. I love when Teddy morphs into Harry, when Harry shows up at Hogwarts to check up on him, and when Teddy toasts Harry-which brought tears to my eyes. Well done, love.
