Yeah I know he likes to make his own twists to actual mythology. But he also likes to make twists within his own story as well, like how Frank is neither ADHD or dyslexic but lactose intolerant. Before the HoO, ADHD & dyslexia was true for every demigod, now we find out otherwise. And we never did find out about Minerva in CJ.

Again, I'm sure Annabeth is the 7th demigod, but I'm just trying to think outside the box and open my mind to other possibilities. Jason isn't technically a son of Zeus, Frank's not a son of Ares, and Hazel isn't a daughter of Hades. For all we know, the same could be said for whoever represents Athena.
