Damian is Roxy Mitchell's fiancé whom she starts avoiding calls from during her stay in Walford. Roxy tells her sister Ronnie Mitchell she is going to leave Damian and never go back to Ibiza, but Ronnie warns her to wait until she gets the money out of his business. They then both get into an argument over the situation during which Damian arrives totally unexpectedly at The Queen Victoria pub. Roxy and Ronnie then trick him into believing Roxy's new boyfriend is Ian Beale and she is pregnant with Ian's baby. Roxy even kisses Ian to prove she loves him with all her heart in front of Damian. Damian then leaves to go back to Ibiza.
Two months later, Damian returns to Walford to be with Roxy, who pretends that she had a miscarriage. Roxy tries not to let him know that she is using him only for the money to help Peggy pay off her £40,000 debts and the funds for her and Ronnie's future ownership of the Scarlet nightclub. On 29 October, Damian attacks Ian in the café when he discovers that he and Roxy were never even in love, and then gets himself arrested by Jack Branning when he "hits" Ronnie (this is set up by Ronnie, when she makes it look like he was sexually assaulting her). Damian then realises that Roxy doesn't really love him, but is using him to get the money he owes her. This is the last time he is seen.
