What wasn’t as clear was how in FTL, Granny had overcome transforming into a werewolf but maintained her keen sense of smell. How did she manage to prevent transforming during wolf’s time?
Maybe Granny figured out a way to control the wolf and will herself not to transform. She obviously had full knowledge of the transformation when it happened, unlike Red who had no idea she was the wolf.
I hate to say it, but it could have been an ‘age thing.’ Like Granny said the only thing she still had of the wolf was the tracking sense and everything else just faded away with time. As Granny aged, the wolf aged too.
