7/10- Unforgiven
Dear Professor Lupin, Harry wrote one tired and hot afternoon not a month after Sirius died. He had received a letter from Mrs. Weasley, telling him that Remus thought Harry was angry at him. And he was, but probably not for the reasons the lycanthrope thought.
With a frustrated sigh, Harry let the pain that had plagued him since he found out who Remus was, pour out onto the page.
Mrs. Weasley tells me you think that I blame you for Sirius' death. I do not. I don't see how I could. I do blame you for other things. I blame you for not trying harder to find me. I blame you for not telling me you were my father's friend. I blame you for never being more than my Professor. I blame you for being the first person to listen to me with affection and respect, and then leaving me all alone, in a world that had turned on its head. I blame you for never hugging me or being what you could have been to me. I blame you for letting your fear get in the way of being there for me.
For these things I will always blame you, though I could never blame you for Sirius. In that, the blame lies on me, and I am sorry for losing you your last friend.
With deepest respect and compassion,
Harry Potter.
Harry never sent the letter. Years later, when Teddy was an adult with two sons of his own, he gave the letter to him when he asked why Harry always called Remus Professor Lupin.
