Mancini is a character who makes a one-time appearance in the Season 2 episode titled The Truth About Holly (episode).
Caitlin nearly has a chopper accident during her movie stunt. Dominic and Hawke believe this is the doing of Ed Aarons who is trying to harass Dominic's niece Holly Matthews. They go in search of Ed Aarons at the premises of Edw. Aarons Inc-Interstate trucking. Mancini is in charge there and tells them Aarons is not there. He is in Mexico and doesn't know when he will be back. Dominic and Hawke ask him to pass Aarons a message. They want him to leave Holly alone or else they will go back to Mexico and bust up his mansion--again.
