Duncan is 16-year-old boxer brought to Walford by Michael Moon. He then befriends Ben Mitchell. When Ben decides he wants to box, his father Phil Mitchell pairs him with Duncan. Duncan tells Ben to look into his eyes as they are fighting, causing Ben to blush.
Later, when Duncan tends to Ben's injured hand, Ben kisses Duncan, and immediately apologies, but Duncan kisses him back. A few days later, they take a break from training and kiss in the alleyway again, and are seen by Patrick Trueman.
Things go wrong between Ben and Patrick, which causes Phil to start a hate campaign against Patrick, so Duncan tells Ben things between them were only a bit of fun, and he decides to change to a different gym. Duncan is credited as Duncan Willis but is referred to as Duncan Wilkins in the show.
