Well the chapter was from Leo's POV. I'd have to re-read it, but maybe everyone else was just more vocal about how they could have done something (I know Jason, Frank, and Hedge all said something). Leo thought it was his fault because he used Nemesis' cookie. Hazel blames Gaea instead because she knows what it is like to spend your life blaming yourself for something that wasn't your fault (because of Sammy, who blamed himself for Hazel's sudden disappearance). However, she may have just been trying to shift the blame onto someone else. Hard to say.
