Saw a bit on TV yesterday, caught the Italy scenes from Part I. Couple things I noticed this time around:
* When Fabrizio goes inside the cafe to fetch Vitelli, he makes sure to bring his shotgun, and Calo also grabs his from the ground and hoists it up in plain view of Vitelli and brothers
* Fabrizio is the first one to notice Appolonia, he gives her a weird look (maybe he even smells her?) when she is descending down the stairs to first meet Michael; maybe part of his treachery had something to do with Mike getting the girl
