Davide focuses on bodybuilding, while Libero and Diana navigate adolescence. Renzo wakes up in the hospital, saved by Luigi. When Sartori confesses to Luigi that he is his real father, the young doctor reacts bitterly, forcing Sartori to cancel his upcoming marriage to Eloisa via letter. Undeterred, Eloisa joins student protests and visits Flaviut in prison. Gabriele tries to reconnect with Davide, only to discover his boxing coach is Margherita’s ex-boyfriend—a revelation that deepens their rift and leads to their separation. Diana falls for Sandra after a club performance and stuns her father by deciding to move in with her. Meanwhile, newlyweds Libero and Marta welcome a baby girl, Nadia, shortly before Marta departs for Africa.
