"Take Trish to Venice." With their next order from the boss, Bucciarati and his crew head to Naples Station. "Use the key at the water fountain with the turtle on the 6th platform." They find the water fountain, but can't find the place to use the key. Meanwhile, Proscuitto and Pesci from the Hitman Team follow Bucciarati and the others to Naples Station. Bucciarati figures out the mystery behind the key and gets on the express train to Florence, and Proscuitto and Pesci follow.
