Bait-and-Switch: The episode gives the vibe that it’s going to be about the girls fighting their way through a horde of dragons to get the Sorcerer’s Stone back. Then they find out there’s only one dragon and that he merely took the stone as a “payment” the school allegedly owes him.
Defrosting Ice King: Fafnir is a greedy loan shark with little faith in magic. However, Akko’s passion for magic gets him to lighten up a little and to recall another young witch who shared Akko’s enthusiasm.
Magic Versus Science: Fafnir the dragon puts more faith in science since he believes magic is dying out and will be overtaken by science.
Pet the Dog: Fafnir may be a greedy and selfish loan shark, but he has no intention to hurt the girls when he catches them trespassing on his property.
Wham Shot: When Amanda and Akko look at the remains of one of the dragons, they find a mechanical skeletal structure.
