Melinda Clarke Joins 'Dallas' as Tracey McKay, a Character From the Original Series

Dallas has cast Melinda Clarke as Tracey McKay, one of Bobby Ewing’s girlfriends from the original series. Clarke — whose credits also include The O.C., Days of our Lives and CSI — will appear in two episodes, beginning September 8.

Tracey was introduced on the CBS version of Dallas in the 12th season, played by Beth Toussaint. The character is the daughter of Ewing rival Carter McKay (George Kennedy), and was briefly romanced by Bobby (Patrick Duffy). The affair ended when he tangled with Tracey’s drug-dealing brother Tommy (J. Eddie Peck). Tracey briefly returned to the series the following season when Tommy was killed off.

Earlier this season, TNT's Dallas introduced Carter's grandson Hunter (Fran Kranz), a childhood friend of John Ross and Christopher's who is secretly helping Nicolas (Juan Pablo Di Pace) with his scheme against the Ewings.
