Chapter 51 - Third Year - The Man Who Cried Wolf

At the Potters' Christmas party, Remus seeks out Darius Barebones to learn about his father Lyall Lupin. The devastating conversation reveals that Lyall was obsessed with werewolf control, that Greyback was once in ministry custody but released due to Lyall's colleagues dismissing his warnings, and that his father may have killed himself after being bitten. Darius's casual mention of werewolf registries and his belief that "only good beast's a dead beast" leaves Remus reeling with the knowledge that his father's death was connected to the very creature his son would become.
