Carter is a lawyer and the former boyfriend of James Nightingale. When Carter arrived in Hollyoaks, he complimented James whilst doing his workout. They ended up talking and Carter revealed that his law firm was looking for a new member to add to his team, which intrigued James. He invited James to lunch with his partner, Lara and James attended with John Paul McQueen pretending to be his boyfriend. The lunch went well at first until John Paul's boyfriend Scott Drinkwell showed up, which causes James' plan to backfire, leaving James humiliated in front of Carter.
The next day, Carter interviewed Joanne Cardsley for the position after James told her about the job, and he offered her the job. When James arrived, Carter revealed that he has hired Joanne. Joanne is surprised that James and Carter knew each other. James revealed to Joanne that Carter was his ex-boyfriend and that him wanting the job himself was for personal reasons. Carter then reminded James that their breakup wasn't his fault and that he should ask his mother if he didn't believe him, which left James confused. Carter said goodbye to Joanne and promised to stay in touch with her.
