In this last segment, Daniela focuses on when the past participle of a verb in the present perfect has to agree (in number and gender) with the direct object pronoun when using compound pronouns. It's a bit tricky.

We learn why Dalmasso asked Mauro to stay on at the Olivetti firm. Adriano pays a visit to Mauro's house to find out if his suspicions are correct.

Peppino buys some groceries for Martino and Marti' is none too happy with the bill. He goes over what Peppino bought, giving the quantity as due and du' [short for due (two)] for the canned tomatoes, beer etc. Often, this due isn't a literal two, but means a small amount. You frequently hear the du' at fruit and vegetable shops or markets, where customers might ask for just a little bit of something, such as "du' ciliegie" [cherries]. The du' is also a polite way of preventing the vendor from heaping produce on the scale.

Ferruccio, the kitchen hand, tells Dante about a conversation he overheard and this creates a little friction between Eva and Dante. Lorenzo hasn't been showing up for meals at the restaurant and Eva learns why.

Marta has conversations with both Manara and Raimondi, neither of which is she too happy about. The term innominato or unnamed makes reference to the evil character in Alessandro Manzoni's novel, I Promessi Sposi (The Betrothed).

The first stop is Italy's easternmost point, the Punta Palascìa and its 19th century lighthouse. Alberto Angela then shows us another site in the Apulia region, Castel del Monte, a breathtaking crown-shaped castle built by Frederick II in the early 1200s.

Daniela focuses on the partitive ne when joined to combined pronouns in the third person singular, masculine or feminine. In this case, the indirect pronoun aspect stays the same in both the masculine and feminine, singular and plural.

Adriano asks Karen Bates to travel to Italy's southern regions to scout out a location for an Olivetti factory. Mauro, after being passed over for a job, decides to go and work for Dalmasso.

Finally, Martino's disappearance becomes known to the townspeople. He is the subject of Don Julio's sermon, and is even mentioned in the Bari newspaper. Martino is absolutely galled by how he's described in the newspaper.

Eva pays a visit to Augusto, a friend and safe-cracking expert, while Lorenzo and Malù break up. Later, Eva and the ladies hold a planning session for their caper.

The squad interrogates Pupi, the murder victim's coworker at the winery. Luca gets to listen in on the interrogation and the ensuing discussions via Toscani's cellphone.

We say goodbye to Agrigento's Valley of the Temples and get a close look at the awesome Riace Bronzes in Reggio Calabria. The two life-size Greek bronzes date to the 5th century BC and were discovered off Riace by a scuba diver in 1972.

Daniela sums up about compound pronouns and explains what a partitive pronoun is. An example of a partitive pronoun is the particle ne (of it, of them).

Teresa is distraught over Libero's marriage and is having a hard time working. Adriano tries to console her and shares his problems with her. Later on she gets a shock.

Peppino goes to see Martino and tells him the truth: that no one in town noticed he was gone. He then does Martino another favor, similar to smashing his cell phone.
