This scene has another complication . The guy in the Gray Hat from earlier with William and Walter who was supposed to be retired along with Abernathy are both present . So the fact that Walter is present there would indicate that it had occurred . I think she sees here new dad then flashbacks to Gray Hat 30 yrs ago , then mixes the 2 together such that you have Walter but lose Gray Hat . Walter throws off the definitiveness of this incident . <| sep |> I do love Hagrid ' s story but I do think a book based on it would be repetitive as the Harry Potter did a great job at going into it . The book would probably be pretty short as well beings that life as a gameskeeper can ' t be all that exciting . <| sep |> Nope . Still a rifle .
