Rest in Peace, Gayle Hunnicutt.
In my opinion JR's previous love stories, first with Lee Ann De La Vega and then with Vanessa Beaumont, are more believable than the one with Callie Harper.
With regard to Vanessa (the actress was almost a double of Linda Gray when she was very young), I can believe she was the first great love of JR who subsequently looked first in Julie Gray and then in Miss Texas Sue Ellen Shepard almost as substitutes , all very similar physiognomically to each other.
Then ... over the years, Sue Ellen became the most important woman, in love and hate.
