Me: So how did Sauron take “upon himself the form
of a werewolf” when a werewolf is a man turned into a wolf? Did he turn himself into a man and then turn himself into a wolf, just to mess with Luthien and Huan? Why not just a wolf then? How do you turn into something that’s already a mix of two things that you’re not either one of?
