- But Prof. Lupin isn't there. Instead, it's everyone's favorite substitute: Snape.
- He says Lupin is "incapable of teaching at the present time."
- Today's lesson: werewolves.
- Once again, Hermione seems to appear out of nowhere to be her usual Brainiac self.
- They discuss the difference between an Animagus and a werewolf.
- What's the diff? An Animagus has choice to transform; a werewolf does not.
- Snape assigns a long essay on werewolves.
