do none of you understand how being someone's niece/nephew works? The fact that Athena is Poseidon's niece does nt mean that Annabeth is Percy's niece.
dude, jason is pipers cousin, pipers mom is cheating on leos dad with franks dad, leo is percy's niece, will is nico's uncle, and clarrise is thaila's neice.
SO I HAVE BEEN READING ALL OF THE JACKSON BOOKS AND IT SAID THAT ATHENA IS POSEIDON'S NIECE, RIGHT, AND PERCY IS POSEIDONS SON AND ANNABETH IS ATHENA'S DAUGHTER AND THEIR DATING. DOES THAT MEAN PERCY IS DATING HIS NEICE!!!
