Giacomo reveals his "discovery" to his family. He tells Mario about the girl he likes. Mario manages to leave with a nice check, signed by Giacomo.

Mario is repaying some debts and buying presents for his family, but his efforts go unappreciated. Giacomo's family is becoming alarmed at how much money he is spending, and decides to do something about it.

Mario manages to put certain ideas in Giacomo's head so that when he gets to the meeting with the notary, he is not the complacent brother everyone is expecting.

Mario gets invited to dinner at Giacomo's parents' house without Giacomo's knowledge. They have him figured out, and ask him to disappear. Giacomo shows up at the office, as promised.

Mario explains karma to a friend. Giacomo surprises his sister at the office. And sister and brother even have a bite to eat together there at the end of the day.

Mario is still in big financial trouble and knows that only Giacomo can help him. What will he come up with next to con his friend into giving him the money?

Maybe, just maybe, Mario is starting to feel bad about what he is doing. Giacomo confides in his sister about the money he needs, and Mario has a surprise encounter at a vending machine he is supplying.

Giacomo finds a way to obtain the money he needs for Mario. There are strings attached, however, and he informs his sister about it. Giacomo makes a surprise visit to Mario's house, and Ginevra makes a surprise phone call to Mario. Things are closing in on him from all sides.

Just when Mario felt he was getting his family back, a little karma comes his way to stir things up.

After discovering that Mario isn't really ill, Giacomo goes looking for Professor Stern once again, hoping to find some answers.

We don't want to give away the ending, so let's just say that Giacomo goes back to the cafe where the redhead works and... who shows up, but Mario.

Journalist Annalena Benini introduces us to different writers from different places in Italy, beginning with Rome, where she interviews Chiara Gamberale, a novelist.

Chiara Gamberale talks about how and where she writes, and how her life has changed now that she has a little girl.

Chiara tells about how she realized she knew how to read, which then led her to begin writing. She wrote her first "novel" in second grade. Where she grew up, on the outskirts of Rome, influence her writing to a significant degree.

Annalena meets up with Paolo Giordano who talks about the trauma of moving from Turin to Rome. Giordano's first novel, La solitudine dei numeri primi (the solitude of prime numbers) from 2008 was made into a popular film of the same name in 2010.
