Charlie Fairhead
Thompson has so-far made four appearances in "Casualty" sister show "Holby City": the show's first episode in January 1999; the second episode to the Christmas crossover in December 2005; another crossover to "Holby City" in February 2010 when Charlie has a heart attack; and the most recent appearance in October 2012 when he interviewed Chantelle Lane (Lauren Drummond) for a full-time nursing position. Thompson also made an appearance in "Casualty" spin-off police drama, "HolbyBlue" for its first episode in May 2007.
Charlie is the lynchpin of the emergency department. He's been there since the beginning (having joined the department more than a decade before Casualty was first aired) and has always proved to be an indispensable, trustworthy and diplomatic member of the team. People look up to him, and he always tries to be there when the ED family need him.
