Maybe Lee Ann De La Vega/Barbara Eden really didn't have that abortion, she claimed she did, or maybe she did get pregnant again even claiming she was barren from that abortion, when she came back to Dallas to seek her revenge on J.R. She managed to end J.R.'s relationship with Vanessa Beaumont by seducing J.R. Having her revenge against J.R
J.R. back in the day, he got around, no telling who the sister is. LOL
But is would be cool to get Barbara Eden on the show even as a guest appearance. Larry Hagman's I dream of Jeannie co star.
