Characters of Casualty
Duffy next appears in the opening two episodes of series 21, in 2006, as part of Casualty's 20th anniversary celebrations. Charlie, paramedic Comfort Jones (Martina Laird), nurse John "Abs" Denham (James Redmond) and SHO Gurpreet "Guppy" Sandhu (Elyes Gabel) head to Cambodia where Duffy has set up a clinic for local people. Charlie does not take to her new partner Mike Hornsey (John Bowe) especially when he refuses to carry out an operation, claiming he has had a drink. When Charlie rings back to the UK to check up on Mike's background, he discovers that he had been struck off, but later Mike tells Charlie and Guppy that he was struck off because he helped his mother die. Duffy is upset that Charlie went behind her back, but they eventually make up.
