The (almost) final scene of Don Camillo's Last Round, and this exchange between Peppone, freshly elected senator, on the train for Rome, and Don Camillo, who went to the station to see him off as a call back to the ending of the first movie:
Don Camillo: I never forgot that you came to salute me when I was going into exile. Now you're leaving. Peppone: I'm not going into exile; I'm going because I won, not because I lost. Don Camillo: You lost your wife who voted against you; you lost your town where you were somebody. You won — what? The honour of being another face in the crowd, a ball in the urn. Peppone: I will always be what I am. Don Camillo: Oh yeah? Well then, when you sit down in that huge sad hall, as if you were in school, then you'll think about everything you left behind. You'll think of what you used to see out your window in the morning while you were shaving; you'll think of your workshop and how you enjoyed tinkering your Sundays away... You'll even think of me, how I'm not there to give you a wallop when you deserve it — which is roughly once a day! Peppone (deeply unhappy): When I come back I'll crush you to a pulp! Don Camillo (just as upset): But you know you're not coming back! And I can't even say "Goodbye, Peppone"... only "Adieu, Senator".
In Don Camillo: Monsignor, some of the village's young Communists go to another city for a protest, which turns very wrong, as one of them is killed. The funeral is a very moving scene; Peppone is one of the pallbearers and is holding back tears, and when the procession walks past the church, Don Camillo himself sounds the death knell — despite his earlier refusal because the dead man was excommunicated — in sync with the "people's bell" Peppone had had installed.
Pretty much all of "The Whistle". Thirteen year old Pino dei Bassi is the son of Cino dei Bassi, a very talented hunter with a gift for shooting and a very distinctive whistle. Cino was one of Don Camillo's best childhood friends; he fell in a ditch with his shotgun, which went off, and died in Don Camillo's arms. Cino's father and grandfather also died in gun-related accidents, so when Pino asks Don Camillo if he can go hunting with him, Don Camillo refuses. But the boy is as sure a shot as his father was; he ends up going hunting all alone with Don Camillo's dog, Thunder. One evening Pino goes to a preserve and shoots a pheasant, but a warden shoots on instinct and kills him. They bury the boy like they buried his father, the warden gives himself up to the carabinieri (because Thunder howled under his window non-stop for twenty nights), and when Don Camillo goes out hunting again, he hears Cino's whistle in the night.
The story of Bianco, the old horse that used to pull the carriage which carried people to and from the old steam trolley. After the trolley was replaced by a bus, the horse was "retired"; then, one day, he hears a whistle that sounds just like the trolley, and takes off at a dead run toward his old post. Peppone and Don Camillo follow him on Peppone's motorcycle, and find the horse dead where he collapsed near the highway. The whistle turns out to come from a steamroller making repairs on the road. At least the poor horse died happy, believing it was the trolley.
