• Li Weide gave Slughorn material for his Ideological and Moral Education Class and suggested that Tom raise a Basilisk to increase the supply of potion ingredients.

• Li Weide showed Slughorn an improved Red Collar and explained that Tom's Parseltongue would safeguard the initial Basilisk-control experiments.
