me too, i doubt that he will die. but yeah me and my friend just thought of something about the prophecy

First I thought that the line

"To storm or fire the world must fall"

pertains to Annabeth and Percy falling to Tartarus due to Leo(fire).

But we can also interpret it as

To Percy/Jason(storm) or Leo(fire), Gaea(world) will fall/go back to sleep. yes. world = Gaea. Since Leo's mom died because of Gaea it seems right that he will have revenge (and yeah he met Nemesis). What do you guys think?
