not nessiserily Zeus could have forgotten about Jason or he knew about Jason but thought it was best to keep him a secret plus Percy made a deal with the gods at the end of The Last Olympian with the gods that all demigods would have to be claimed by the time they were 16 and at Camp Half Blood so......... there is still the possibility that Jason is the son of Zeus
