Valene's storyline in her first two episodes on Dallas focuses on the rebuilding of her relationship with estranged ex-husband Gary Ewing. When Valene arrives in Texas to find her daughter, Lucy Ewing, she is brought back into the drama of the Ewing family. Upon arrival, she is reunited with Gary with whom she slowly falls back in love. Once Dallas became a hit, series creator David Jacobs proceeded to launch a spin-off series titled Knots Landing, which would feature Valene and Gary prominently. The actress had strong input on how they would create her character outline. She recalled, "I remember going to wardrobe and getting a peachy pink waitress uniform, and the shoes. And then I was trying to get that Texas sound, her all important accent. And so we created her layer by layer."
