Percy has shown himself to be pretty smart in the series. I mean is he book smart, good gods no! However, he managed to outsmart Chrysaor in The Mark of Athena. Even back in The Son of Neptune, when he had no memory, managed to beat Phhineas in a bet. Even Hazel commented that Percy was smarter then he let on and made a mental note not to underestimate him again.
