Glow in the sky / Eternal youth - S5.E2

Ezio and Cesare, certain they're in contact with aliens, become convinced the world is about to end and decide to steal a submarine to save themselves from the Great Flood. For Giulio, however, the most important thing is to make a good impression on Lucia. While Alice and Rudi grow increasingly cold, Diego meets Miriam, and they immediately fall in love.

Giulio finds himself dealing with a young suitor who, because of Ezio and Cesare's intervention, threatens to report him in revenge for being rejected. Lucia's intervention brings the girl to her senses, and Giulio, happy at his newfound connection with his ex-wife, can only be stunned when she announces she's about to return to Venice.
