Judging from the previous books in the HoO and PJO, this is what I have thought.

Death- I suspect that someone is going to die, and it's going to be either Nico or Leo. Nico because he's sort of a 'I'll help you when I want to but I walk alone' type of guy. His death would probably depress Hazel, Percy, and Annabeth, while demoralizing both the Roman and Greek Camps. Leo because Gaea has said it herself: "''They need you desperately. In some ways, you are the most important of the seven-like the control disk in the dragon's brain. Without you, the power of the others means nothing. They will never reach me, never stop me. And I will fully wake." ''-Gaea talking to Leo (pg. 253). If Leo is so important to the Seven, then whatever way to get rid of him is by killing him?

Epic Battle Between Friends- I think that there is going to be a epic fight between Leo and Percy and Jason. Remember the line in the prophecy: "By storm or fire, the world must fall"? Well, a storm consists of both lightning and water (Percy and Jason), while the fire is obviously Leo. So I think that either both Jason and Percy are going to fight some mysteriously empowered Leo, or vice versa to prevent the world from being, well, destroyed.

Someone Gets Left Behind- Since the Doors of Death have to be closed on both sides, then I think someone is going to get left in Tartarus (either Octavian, Reyna, or Leo).

Well, that's what I think. Sup everybody.
