Terry is a former professional boxer who has served time in Wormwood Scrubs prison ("two years for GBH and three for attempted robbery" according to a police sergeant in the first episode, "Gunfight at the OK Laundrette", although other episodes slightly contradict this and the overall charges are often quite vague), having served a substantial term because he would not become an informant against his co-accused. With few options, Terry is employed as Arthur's minder on vague and ungenerous terms, with it often being hinted that Arthur has manipulated him into this job, and indeed is seen to continue to manipulate Terry throughout the character's run in the series, despite his often attempting to find other means of employment and break free from Arthur's control. (The later feature-length special "An Officer and a Car Salesman", which leads into Series 7, Terry's last stint in the series, begins with Terry once again inside, this time after being caught with some of Arthur's hookey merchandise). In Terry and Arthur's final episode "The Wrong Goodbye", it is suggested that one of Terry's prison terms was taken in place of Arthur and explains why Arthur and Terry have a deep bond, though casts Arthur's treatment of Terry in far less flattering light.
