[He's trying. Percy will always try, even if he doesn't always succeed.]

I'm not saying it's definitely gonna work, but there's a chance. The Hypnos kids - some of them can do this thing where they go in dreams and... something like that. Anyway, I think the idea is that you never really forget stuff, it just falls away or fades or something, and sometimes they can use your dreams to help you get back whatever you forgot. Especially if there's some kind of a block on it, and it's not from when you're a little baby or something like that.

I don't know it'll work, but if anyone can do it, they can. It's worth a shot, right?
