Calenzano felt the need to tell Imma and Calogiuri some details about his childhood in Switzerland so that they would be able to understand what had happened between him and Stella.

In front of Imma, Calogiuri, and Diana, Calenzano describes every detail of when he went to Stella's apartment to see her. He's distraught, as he relives the experience.

Calenzano finishes telling his story and Calogiuri takes him away. Stacchio's teacher stops by Imma's office with a pupil, Nicolas, who has a story of his own to tell.

Pietro goes to his saxophone teacher's house to help her with a technical problem. At home, Imma gets an important phone call that has nothing to do with the case she just solved.

Imma appears to be on the psychiatrist's couch, describing a dream, but the situation becomes more and more bizarre and we don't really know what's real and what isn't.

Imma had been dreaming and wakes up to a call from Don Mariano who wants to see her, urgently. But she has another emergency to deal with first.

Imma is still worried about her husband ending up in the hospital when, back at work, Diana has bad news for her. Imma remembers her appointment with Don Mariano, but that's not the worst of it.

Imma goes to the Foundation where Don Mariano had his office. She and the team look for the tablet and talk to the young man who helped out there. They also talk to the housekeeper Ilona, who says there were plenty of people out to get Don Mariano.

Imma goes to the hospital and can't help looking at Pietro's phone while he is sleeping. Back at the office, Diana is in tears because her husband wants a separation.

Imma is talking with Mottola to find any connections with Don Mariano's death. He is accusing the deceased of not having helped him, and at a certain point, she says: Ma si rende conto? (but do you have any idea?) For more on this expression see our lesson. Back home, Imma is irritable, but she can't talk to her daughter about the real reasons she is upset.

Comedian and actor Caterina Guzzanti is a guest at a middle school in Afragola, in the province of Naples, a school named after Rita Levi Montalcini. Guzzanti meets with the students from the theater class for a lesson on the imagination, which has a lot of importance in her work but was also very important to the great researcher from Turin, Montalcini.

Rita Levi Montalcini talks about when she won the Nobel Prize in 1986. Her niece, Piera, tells the story from her point of view, and Paola Tarassi, a research student of hers, tells about studying with her after she had already won the Nobel.

Rita Levi Montalcini felt that imagination was the "secret sauce" of her research. And this encouraged her to turn to young people, who have plenty of imagination. She didn't hesitate to teach kids of junior high school age, which came as a surprise to some people, since she was a winner of the Nobel prize.

Rita Levi Montalcini dedicated a great part of her life to young people, especially young researchers, and though she had no children of her own, she felt that all kinds of young people were like sons and daughters to her.

Rita Levi Montalcini talks about what, as a little girl, she wanted to be when she grew up. One of her main goals was to help women, especially ones from poor countries, become what they were meant to become.
