S1, E6: The Chamois resort is thunderstruck by the revelation: if Father Cyril isn't Emma's biological father, Marie-Odile conceived her with another man, which means she must have cheated on Etienne 25 years ago. Even so, Marie Odile swears to high heaven that she didn't have a lover. Her protests don't convince anyone: not Emma nor the Bernards, and least of all Etienne.Humiliated, betrayed and hurt, Etienne leaves her right then and there and returns to Paris. His departure is bad news for Krystel, whose co-workers have accidentally caused a fire while searching his office. If Etienne goes back now, everyone is going to get fired.
