"Percy didn't feel powerful. The more heroic stuff he did, the more he realized how limited he was. He felt like a fraud. I'm not as great as you think., he wanted to warn his friends. His failures, like tonight, seemed to prove it. Maybe that's why he had started to fear suffocation. It wasn't so much drowning in the earth or the sea, but the feeling that was sinking into too many expectations, literally getting in over his head."
