The Mark of Athena
Aphros and his comrades rescue Leo Valdez, Hazel Levesque and Frank Zhang from drowning in the ocean after they defeated the skolopendra. He later interrogates Leo in order to figure out why they were here and whether they could trust them. He listens to Leo tell his story about their quest, and in the process of listening knits a bonnet. He later agrees to send a group of mer-heroes on a quest to save the creatures trapped by Phorcys, and gives Leo a plate of Brownies and the recipe.
