List of characters in the Camp Half-Blood series
Connor and Travis Stoll: Homonym to "stole". Hermes is the god of thieves. Children of Hermes. Percy himself pointed this out but neither of the Stoll brothers understood the joke.  As well, Con, shortened from Connor, is another word for scam or trickery, as Hermes is the god of trickery.  Travis can be seen connected to the word travel, and Hermes is also the god of travelers.
