During the first episodes of the series, the teenaged Lucy (Jock Ewing's granddaughter) is seen sleeping with ranch foreman Ray Krebbs (Steve Kanaly). Later, in season 4, Ray was revealed as Lucy's uncle, an illegitimate Ewing son through an extramarital affair that Jock Ewing had during World War II. Unhappy with his small, one-dimensional role, Kanaly had considered leaving the show; to add depth to the Ray character, Hagman suggested that the writers create a plot wherein Ray becomes half-brother to J.R., Gary, and Bobby, noting his resemblance to Davis. The episodes where Ray and his niece Lucy had a fling are, as Kanaly told Dinah Shore in an appearance on her show, "prayerfully forgotten, I hope."
