Not sure if someone already answered your inquiry, but writing in on Poseidon's page that he and Hades are brothers doesn't count for the in-show universe unless the writers make them brothers on the show. The fact they are brothers is true for Greek mythology, but the Once characters are not siblings because that hasn't been proven or shown.
