Correct me if i'm wrong, but wouldn't Percy and Annabeth be related? because Athena is berkata to be the daughter of Zeus, which would make Poseiden the uncle of Athena, and that would mean that Athena and Percy are cousins.
Whoa, and that would make Percy Annabeth's uncle... atau would he be her third cousin? I dunno. But in the book, it says that since the gods have no DNA, it would be alright for them to like each other. And like Jez11 said, Zeus and Hera were brother and sister, so I don't think they really care. xD
yah,and if athena is a daughter of zues and percy is a son of poseidon athena and percy r cusins and since annabeth is a daughter of athena percy is annabeth's uncle,so annabeth just made out with her uncle!!!but u know,gods dont have DNA so it dusnt count
