Phineas said he is the son of Neptune in the books and we can only go by the book. Arion on the other hand again is in greek myth but neptune is as much the Horse god as he is an sea god where posiden is an sea god who made Horses. Also their are many meaning of the word lost, like there to you. Leo can a Lost hero because he would always run away. Beckendorf and Beauregard are also lost heros because their cabins went downhill when they were lost.
