I'm betting that that 'unknown' camper is Annabeth. Who else would it be? AND, me and my friends are betting (literally) other people that Frank will be a son of Artemis. It's impossible, you say? Heh. Well, PJO fannigans, Rick Riordan said that everyone would be surprised by who Frank's godly parent is. AND, he can change form... Or at least it's rumored. Hazel is probably a daughter of Apollo or Hermes.
