Now reunited with Gerry, Simon, Lucy and Harry decide that they must try to get to Maracoomba Island. Gerry says this is the mysterious Astrid where they believe that they will find the answer to their friends' disappearance. The group discover their faces on posters all over the area and Simon is recognised and challenged. Is the game up?

Lucy and Harry realise that if Simon is still in the camp it means that the others who have split and disappeared with red eye are probably still there too. They spot their missing friends playing in a rock pool and realise, as they did with Simon, that something is definitely not right about them.
