We also have a kind of interesting hint as to Hazel's parent. Think about this, if the 7 Olympian week gods are the parents of the 7, all that is left is Pluto/Hades and Athena/Minerva. In Hazel's picture, she is riding a horse when we know from the times Nico tried to ride one, they dont like him at all because he smells of death. That can only mean that Hazel is a daughter of Athena/Minerva. (Waits for people to get mad at me for thinking that Annabeth may not be one of the 7)
