I also feel like they only need the blood of two demigods, not really their lives. Though I feel the Seven will have to kill the sacrifices in the end. Maybe the blood will be part of Gaea's resurrection, so a part of the two demigods will go to Gaea, and killing one of them will cause pain to Gaea or decrease her powers or something. So maybe the Seven will have to kill the two demigods to defeat Gaea.

Now about the sacrifices. One boy and one girl right? My initial bet was Hazel and Frank (so even though Rick kills two, it will still be a happy ending). But I have a hunch that it will be Hazel and Leo. I feel Hazel will die in the end, cause no mortal has come back alive and lived very long. And Leo can go to Ogygia after he dies, granted by the gods since he sacrificed himself.

You guys remembered in The Son of Neptune that Mars told Frank that he'll make a sacrifice that Percy can't make (because of his fatal flaw) and only Frank has the duty to do it? Initially I thought that Frank will sacrifice himself because Percy can't, then I tried to look at it from a different angle. What if Percy doesn't have courage to kill one of the Seven(as sacrifice), and only Frank has the courage to kill the him/her(or both). So I see Frank killing Hazel (and maybe Leo too) just saw they can weaken(or kill) Gaea (and maybe Jason will deliver the final blow).

I think we shouldn't be closed to the idea that more of the Seven will die though.

And random thought: To storm or fire the world must fall.

What if this line literally meant fall. You know Rick. He can use the literal meaning. And Rick can also direct our attention from what really would happen. Like in HoH when I thought that Nico will die because of the oath
