Ir really isnt that hard to understand. There has been a Roman/opposite gender counterpart for some of the seven gods of Olympian Week so far. Nico, son of Hades and Hazel, daughter of Pluto. Thalia, daughter of Zeus and Jason, son of Jupiter. Clarisse, daughter of Ares and Frank, son of Mars. The only three that dont have one (as we dont know who the last child is) is Aphrodite, Hephaestus, and Poseidon. However, that is most likely because on the Greek side, the child of Aphrodite and Hephaestus are new and we dont know all the Roman Campers.
