Jimmy Dockerson was a mechanic at Premium Motors and a henchman of Tony Gordon, sabotaging the clients of Kevin Webster. Several months later, Jimmy reappeared when Tony discovered that his fiancée Carla Connor had an affair with her brother-in-law Liam Connor. Tony arranged a hit-and-run in order to murder Liam, hiring Jimmy to carry it out. In December, Jimmy met up with Tony and told him not to call them again. They were spotted by Jed Stone, who was looking for his cat, and was suspicious of Tony being a killer. When Tony strangled Jed and thought to have killed him a few days later at Christmas, Tony phoned Jimmy to ask for his help to hide the body, but Jimmy hung up on him.
