By the time Mustang Sally cracked Bryan with the club, (Fore!) Vito was in Gigi's crew and no longer a contractor. He only made that one appearance as Vito the civilian outside of Beansie's place. I'm sure at that point they hadn't decided to give him a bigger part. You were right. In fact doesn't Vito say something like "I want this guy to bleed from his ass, Skipper." about Sally to Gigi when they're all around Bryan's hospital bed? Hahaha. I'm also assuming that Sally was at least an associate, he was known to the crew and he was Bobby Sr.'s godson.
