Later, during a game of hide and seek, Sophie falls into a hollow tree and disappears. Jean and Marguerite help her out, while Leon stands, frozen with fear. Mr de Ruges wants to teach his son a lesson and as Leon runs away, a shaggy looking man with unkempt hair comes out of a bush. It turns out he is a sailor looking for his family. His name is Blaise, and he was the Sybille's first mate. Sophie realises that she and her father were not the only survivors of the wreck and that Paul could still be alive. She is the only one who knows that Blaise is father and husband to the Lecomte women and has the privilege to witness their reunion.
