We're still at the Camposanto in Pisa. Alberto Angela shows us a wonderful fresco of the Last Judgment, and tells us the story of the artist as well as what is depicted.

Marika and Daniela continue their conversation about making conversation in Italian. They even talk a little bit about baby talk, Italian style, including the vezzeggiativo (affectionate) form of adjectives.

Two very important question words dove (where ) and quando (when) dominate this romantic summer song. This song is very ballabile (danceable) making it a very popular summer hit. From the Italian band, Benji & Fede.

Maria Inglese, an Italo-German artist, sings a famous song by Lucio Dalla, dedicated to the Neapolitan opera singer Enrico Caruso. Even though the song uses ti voglio bene, the generally less romantic version of "I love you," it was likely meant romantically here, as Caruso had fallen in love with and married a younger woman shortly before his death.

A student asked Daniela to explain the difference between finché and the adverb fino. In fact, these words are tricky for English speakers to grasp. We're talking about "until" and "as long as," and in questions, "how far" and "how long."

Nino La Martina is questioned by Luca. Toscani and Lara's injuries are being taken care of, but Luca offers to take Lara to the emergency room. She has another suggestion to make.

There are several couples in this segment, in various stages of breaking up. Some, but not all of them are even coming to their senses.

This new episode begins with a botched order at the restaurant and a curious conversation between two customers, which Andreina is overhearing, or rather, eavesdropping on.

The best way to get around Lucca is by bike. Arianna rents one and enjoys riding along the amazing walls of the city, still intact after centuries.

They go to dinner with Francesco and Matì and gently encourage the couple to think hard about what they want. It's natural for memories to come bubbling up from when they were courting.

The fresco depicting the Last Judgement is almost like a photograph of the Middle Ages. Alberto Angela shows us where the sinners ended up and what happened to them in Hell.

This single, Vento sulla Luna (Wind on the Moon) provides plenty of expressions and modi di dire (ways of saying things) to boost your vocabulary. It was written and is performed by Italian singer-songwriter Annalisa in collaboration with Rkomi.

In English, the difference between "until" and "as long as" is quite distinct, but in Italian, it's a little blurry because the presence of the negative word non (not) might change the meaning of a phrase or it might not. When the meaning is not altered by its presence, the word, in this case non (not), is "pleonastic." We're talking about finché and finche non.

Ada and Pio go dancing, but when they get back to her place, they get an unexpected interruption. A bit later, Ada innocently reveals some new elements to the case, and Luca comes back to life from his doldrums.

Mara is bummed out, for sure. Felice too! Delfo, on the other hand, shows a side of himself no one has seen before.
