The Testarossa (literally "red head") is considered to be a supercar par excellence. For a brief period, it was the fastest production model in the world.

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.

Andrea continues to be mistrustful of what Marta is intimating to him. She mentions a house she is borrowing ai Ronchi (in the Ronchis). This prompted us to want to find out where this place is and why she says it in the plural. Here (link to lesson) is what we found out.

This segment is about the film that was made of the Diabolik story. Not everyone was satisfied, including the Giussani sisters, but in those days, certain international standards had to be respected.

René Arnoux is back, telling us more about the Ferrari Testa Rossa, and some interesting facts about the evolution of the name. He also mentions the famed TV series, Miami Vice.

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.

Cioni is very suspicious about Marta's true intentions toward Andrea. The others begin talking about their past relations and aspirations.

We have a look inside the 12-cylinder engine of the Testarossa to see what kind of grade it will receive out of ten.

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.

At the party, tension is high among the friends. Harsh words are exchanged.

Tex Willer is the main fictional character of the Italian comics series Tex, first published in Italy in 1948. The series is an Italian take on the American Old West.

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.

The party is over and it is time to clean up and pack up. Cioni seeks out Ilaria to talk about her situation.

What kind of guy was Tex? For the most part, he was tutto d'un pezzo (a straight shooter). But sometimes it would depend on who was writing the story.

What stands out in this segment is the fact that the Bianchina was the iconic automobile in the beloved 1975 movie, Fantozzi.
