In the early seasons of Dallas (1978)

 In the early seasons of Dallas (1978), Ray Krebbs and Lucy Ewing are shown having a secret romantic affair, meeting in the Southfork barn and hayloft while she is still a rebellious teen and he is the ranch foreman. Their relationship is portrayed as a troubled, on‑and‑off fling that has to be hidden from the Ewing family and ends when the risk of discovery becomes too great.

Later in the series, it is revealed that Ray is actually Jock Ewing’s son, which means Ray is Lucy’s half‑uncle; after this family connection comes out, the show quietly drops any mention of their past romance and keeps their interactions respectful and non‑romantic. Writers and cast have sometimes noted in interviews that this early storyline is treated as a youthful mistake and is not revisited, allowing both characters to move on to healthier relationships.
