Walker, Texas Ranger
His partner and best friend is James "Jimmy" Trivette (Clarence Gilyard), a former Dallas Cowboys player "Go Long T" who takes a more modern approach. Walker's young partner grew up in Baltimore and used football as his ticket to college education.  He was dropped from the team after he tore up his shoulder in a major game, which led to his career in the Rangers (often making references to watching the "Lone Ranger" and how C.D. Parker mentored him as a Rookie Officer). Trivette also works inside the office using computers and cellular phones to collate information of the people who have been taken into custody. Walker also works closely (and shares a mutual attraction) with Alexandra "Alex" Cahill (Sheree J. Wilson), a Tarrant County Assistant District Attorney, who on occasion puts up a frown if Walker does not obtain results in time. He also gets advice on cases from C.D. Parker (Gailard Sartain (pilot season), Noble Willingham (seasons 1–7)), a veteran Ranger (later inducted into the Texas Rangers Hall of Fame) who worked with Walker until retiring to operate a small restaurant and bar called "CD's Bar and Grill", a restaurant widely known in the series for its chili. In Season 7 two rookie Texas Rangers, Sydney Cooke (Nia Peeples) and Francis Gage (Judson Mills), are assigned under Walker and Trivette's command.
