Here's the next one.

So in the blood of Olympus, we don't get to see Percy's POV. Actually, he doesn't have many significant moments in that book at all. Well, except for two.

The first would be when the seven were trying to find and "subdue" Nike. It was in Leo's POV. In this series of chapters, Percy opens up to Leo about calypso, and they make up. They supposedly become somewhat good friends after that, but it's hard to tell because nothing else significant was shown between them. Not even a simple conversation. But we can always guess.

The second would be with Jason when they were underwater, trying to stop Kymolopia. During this, Percy also opens up to Jason, getting some things off his chest.

So basically, the only significant things Percy did in that entire book were opening up to jason and leo. Storm and fire.

My theory is that sometime between blood of Olympus and house of hades, Percy figured out that whoever killed Gaea, storm of fire, they would die doing it. But he didn't know which one was going to die, so he talked to them both, clearing his conscious, before it was too late.

Now, I only half believe in this theory, because if it's wrong, that means my other theory is correct, and I have a lot of evidence for that one. I won't be able to post it, though, until my other story, A Deadly Secret, reaches a certain point without spoiling it. Anyway, that's all. Bye.
