4x14 - The Cesaronis

Marco and Eva, after the shock of Marta's disappearance, realize they've spent too much time at work and too little time with their family. They decide to treat themselves to a relaxing day at the beach. But Marco has a secret that's making him feel bad, and it will come out, upsetting his relationship with Eva. Walter and Carlotta also face a moment of truth: they love each other. She leaves her husband, and he leaves Alice, who, however, doesn't know about Carlotta.
