1. The writers can't seem to decide on what the kids know and what they don't know. If they don't know anything about intimate displays of affection let alone sex, how come the boys like to rubberneck at the girls when they're playing on the sand? .... do they know what it means?? If they're told their only purpose is to fight, how come they're allowed to run around a beach willy nilly next to an abandoned village?
