Dallas

In the first episode of Dallas in 1978, Bobby Ewing brought his new wife to meet his family at Southfork Ranch. However, Bobby's family were dismayed to discover that Bobby's wife was Pamela Barnes (Victoria Principal, briefly Margaret Michaels), the daughter of Digger Barnes (Keenan Wynn, originally David Wayne) and the sister of Cliff Barnes (Ken Kercheval), both of whom were arch-enemies of the Ewing family. In 1982, Bobby and Pam adopted a boy named Christopher (Joshua Harris, originally Eric Farlow), who was the biological son of J.R.'s deceased sister-in-law, Kristin Shepard (Mary Crosby). Pam had always wanted a child but was unlikely to be able to have one of her own. Bobby's sister-in-law, Katherine Wentworth (Morgan Brittany), later had an unrequited crush on Bobby and began to become obsessed with him. Katherine broke up Bobby's marriage to Pam by writing a letter (pretending to be Pam) addressed to her lawyer. Bobby turned to childhood sweetheart Jenna Wade (Priscilla Presley; previously Morgan Fairchild and Francine Tacker) and they became engaged. Katherine ran Bobby down with her car, where he later died in hospital from his injuries. However, a year later, the storylines of the preceding season, including the accident and death of Bobby, were nothing more than a lengthy dream of Pam's. Bobby and Pam were reunited but Jenna discovered that she was pregnant with his child. Bobby wasn't interested in getting back with Jenna, and Jenna later gave birth to his son, Lucas Krebbs. When Pam was involved in a car crash which resulted in her suffering severe burns, she disappeared from the hospital and divorced Bobby and gave him sole custody of Christopher. Bobby became close to April Stevens (Sheree J. Wilson) and they began a relationship and eventually married. However, while on their honeymoon in Paris, April is kidnapped and later shot; she dies in Bobby's arms.

Bobby is first on the scene after hearing a gunshot from J.R. (Larry Hagman) room uttering the words "Oh my God." The camera never shows what Bobby actually saw and it was thought J.R. committed suicide, although in subsequent films it was explained J.R. shot a mirror.

J.R. Returns and War of the Ewings

In J.R. Returns, Bobby had a relationship with Julia Cunningham before taking over Ewing Oil. In the follow-up film War of the Ewings, he is no longer with Julia and the reasons are not even explained. He eventually starts a relationship with European oil heiress Jennifer Jantzen, who was a business associate of his brother J.R. and whose father's company Jantzen Oil was saved from bankruptcy by J.R. Between 1996 and 1998, Bobby is CEO of Ewing Oil. In 1998, Bobby retires from Ewing Oil and begins travelling with Jennifer Jantzen.^[5]

Dallas (2012)

By 2012, Bobby has remarried again, this time to a woman named Ann Smith, and is the owner of Southfork Ranch, according to the terms of Miss Ellie Ewing's will (in season 14 (ep. 353), Miss Ellie had deeded Southfork to Bobby while she was still alive, thereby suggesting a continuity error). Bobby has retired from the oil business, believing that alternative energy is "the future", a belief he shares with his now grown adopted-son Christopher, and is content to raise cattle on the ranch. He has decided to sell Southfork, due to his contracting a gastrointestinal stromal tumor (GIST) and resulting fears that he will not be around to keep the ranch safe, and that Christopher is not yet ready to take over from him. Once again, this brings him into conflict with his older brother J.R. and his nephew, John Ross Ewing III (who has discovered oil on the ranch). Bobby is shocked and saddened when he finds out his brother J.R. is dead. When J.R.'s will is read Bobby receives J.R.'s entire boot collection on the condition that he keeps them cleaner than he keeps his own. Also an old letter from Miss Ellie reveals that John Ross gets half of Southfork. Bobby doesn't agree but goes along with it for now, although it later leads to some disputes between Bobby and John Ross. Bobby also learns that his first wife Pam died of cancer in 1989.

Knots Landing and Bobby Ewing's death

As many storylines on Knots Landing depended on the actions of several characters following the death of Bobby Ewing in 1985, the subsequent dream revelation from Dallas in 1986 did not get applied to the continuity of Knots Landing. Bobby's return was never addressed or even mentioned and, following this, no further crossover storylines were featured on Knots Landing.
