Frieren and Fern wonder what type of good smell the spell produces. They try it on Stark, and find that he smells like grilled meat. The two conclude that the smell is based on the user's definition of a good smell. Stark asks what's for dinner, and both Frieren and Fern exclaim that they want meat, scaring Stark.
