Highlander S02E11 - The Fighter

MacLeod's old friend Tommy Sullivan is a scrappy little Irishman, a one-time boxer turned trainer, who can charm anyone into anything. He charms MacLeod into backing his current boxer and charms Charlie into playing Cyrano to help him woo a shy waitress. But when a rival manager who was trying to steal Sully's fighter turns up dead, MacLeod's opinion of his old friend begins to be altered forever.
