Clarisse La Rue and Percy Jackson are trying to fight off Clarisse's immortal half-brothers, Deimos and Phobos. They ended up at Staten Island Zoo after Deimos mentioned that Ares' chariot was "in a small zoo" (driving Ares' chariot was a test for all of his offspring). When Percy and Clarisse arrived, they were confronted by the two immortal brothers which ended up in a massive brawl. This ended with Percy saying "They may scare you, but they are wimps when it comes to fighting."
