Back at school, the girls are excited to see their sister, Wen-lin, back. She's brought a bunch of snacks for them to try. One of the snacks is called "halcyon fruit," and it's a great way to "catalyze" a plant. The teacher tells the girls that they'll learn how to use this fruit to "precipitate" a flower's growth. They'll also learn to use a broom to do this. Wen-Lin asks the teacher why they can't use wands, and the teacher explains that wands are easier to use than brooms, since they're lighter and easier to carry. The girls are psyched to try this fruit, and they all do the same thing: they eat it, and it heals all sorts of wounds and pains. They wonder why they haven't been able to use the fruit's healing powers on their own plants.
