User blog comment:Rwtia64/`Percy? not a child of this Great Prophecy?/@comment-3007773-20101221023146

I think he will be one of the seven because he's like, a child of the Big Three. And I know Jason, Piper and Leo are part of the seven demigods that will "answer the call". It says in The Lost Hero. And I want Percy to be one of the seven, too. I think it says Percy was one of the seven in The Lost Hero... I lent it to a friend right now, so when I get it back, I'll check to see.
