Gary remained in California, free from the pressures of his family, although he returned to Dallas on several occasions: to visit J.R. in hospital after Kristin Shepard (Mary Crosby) tried to kill him; for Lucy's wedding to Mitch Cooper (Leigh McCloskey); to support Miss Ellie after the death of his father, Jock; and for Bobby's "funeral" during the dream season.
They succeed in doing so, which leads to Lucy engineering a reconciliation between Valene and Gary when her uncle Bobby Ewing (Patrick Duffy) and his wife Pam (Victoria Principal) discover him working in a Las Vegas hotel.
She talks to Garrison at the grave, confiding that she is upset how her family is slowly disintegrating - Bobby has died, J.R.'s wife Sue Ellen (Linda Gray) has left him and taken their son John Ross with her, Gary lives in California and granddaughter Lucy (Charlene Tilton) has moved to Atlanta.
Kristin also appeared in the second season of Dallas spin-off Knots Landing, being bailed out of prison by J.R.'s brother Gary (Ted Shackelford) and his wife Valene (Joan Van Ark).
To avoid the scandal of an unwed teenage pregnancy, Jessica gave the baby to her brother Clayton and his wife Amy, before moving to England and marrying a member of the aristocracy, Lord Montford.
She was adamant that the baby was J.R.'s, but J.R. refused to believe her and Cliff was threatening her with a paternity suit; Dusty offered Sue Ellen genuine love and affection, and they quickly began an affair.
His ploy failed, however; his wife Cally (Cathy Podewell) and son James Beaumont (Sasha Mitchell) had arranged for him to be permanently institutionalised, and Jessica had been moved to a different location soon afterward.
The birth of John Ross - named after his grandfather Jock (Jim Davis) - was traumatic, being delivered by emergency caesarean following Sue Ellen's involvement in a drink driving incident.
Calhoun (Hunter von Leer); his father's remarriage to a much younger woman, Cally (Cathy Podewell); moving to England with his mother and new stepfather, Don Lockwood (Ian McShane), and travelling back and forth between London and Texas; and the sudden arrival of his elder half-brother, James (Sasha Mitchell).
Mitch was amused by Lucy's upper-class attitude, especially because he himself was from a poor background; his father had died when he was a teenager and Afton was younger, meaning their mother Arliss (Anne Francis) worked several jobs in order to support the family.
By this point in their marriage, Mitch had become a successful plastic surgeon at Dallas Memorial Hospital and had embarked on an affair with an older patient, divorcée Evelyn Michaelson (Patty McCormack).
Although Lil enjoyed not having to keep Mickey in check, she felt lonely and constantly called the Krebbs' in Dallas; in the end, Donna convinced her to fly down from Kansas and stay with them.
Lil was present at Southfork when Sue Ellen Ewing (Linda Gray), having relapsed into alcoholism after discovering her husband J.R. (Larry Hagman) in bed with oil magnate Holly Harwood (Lois Chiles), tries driving off the ranch in J.R.'s car.
During season 9, Ray's sentence affects his and Donna's adoption of Tony (Solomon Smaniotto); to try and save their case, they fly Aunt Lil down from Kansas to give a full explanation of the story.
At that time, Lucy was recovering from both her divorce from Mitch Cooper (Leigh McCloskey), her rape at the hands of psychotic photographer Roger Larson (Dennis Redfield) and terminating the subsequent pregnancy.
However, these plans were cut short when, after discovering her husband J.R. (Larry Hagman) in bed with oil magnate Holly Harwood (Lois Chiles), Lucy's aunt Sue Ellen Ewing (Linda Gray) suffered an alcoholic relapse and, while drunk, stole the keys to J.R.'s car in a bid to leave Southfork.
Ray took the blame for turning off the machines in order to spare Lil anymore upset, and was subsequently charged with Mickey's murder; however, a sympathetic judge only handed him a suspended sentence.
She confided this in J.R. Ewing (Larry Hagman), Clayton's future stepson, who disliked the idea of his mother remarrying; finding common ground, they agreed to try and prevent the wedding.
However, J.R. soon discovered why Clayton was apprehensive about having Jessica visit: she was mentally unstable, and in order to stop the wedding happening she kidnapped Miss Ellie by placing her, bound and gagged, in the trunk of her car and driving across Texas.
Horrified, and regretting ever plotting to stop the wedding, J.R. pursued Jessica with help from his brothers Bobby Ewing (Patrick Duffy) and Ray Krebbs (Steve Kanaly), eventually tracking her down to a motel in the desert.
Clayton and Miss Ellie attend the will-reading, as does Atticus' twin Arlen (John Larch) and friends Carter McKay (George Kennedy), Curley Morrison (Charles Cooper) and "Rabbit" Hutch (Eddie Firestone).
The police search for her, but she evades them and waits until the Oil Baron's Ball, when Atticus Ward - who had not died in the shipwreck, and had been stranded on an island in the Bahamas - was poisoned while giving a toast.
By the time J.R. manages to escape, with help from his estranged wife Cally (Cathy Podewell), he learns that Carter McKay had already bought Jessica's shares from Dusty, who has controlling interest in them while she is institutionalised.
Deciding to claim her share of the company, Jamie journeyed to Southfork Ranch, where she was eagerly welcomed by all except her cousin J.R. (Larry Hagman), who remained suspicious of her and accused her of being an imposter.
When Jamie presented her evidence that Ewing Oil was split equally between the three original founders, she started receiving attention from Cliff Barnes (Ken Kercheval), the brother of her cousin Bobby's (Patrick Duffy) ex-wife Pam (Victoria Principal).
They were extremely protective of Cally and when they found her in bed with J.R. Ewing (Larry Hagman) at the hotel, they marched him to the police station and had him arrested and imprisoned in a chain gang for rape.
When it is made public that James is the son of J.R. Ewing (Larry Hagman), Debra Lynn approached J.R. with both the news of their legal marriage and J.R.'s grandson, Jimmy (Chuckie and Kenny Gravino).
Despite searching Digger's house, neither Pam nor Maggie could find the paperwork; it was eventually found, after Bobby urged his brother J.R. (Larry Hagman) to intervene with government officials.
The deaths of Tyler and Catherine, coupled with Digger's alcoholism and lack of a job, drove a miserable Rebecca into having an affair with Hutch McKinney (William Watson), a farmhand at Southfork Ranch.
After leaving husband Digger Barnes (David Wayne/Keenan Wynn) and her children, Cliff (Ken Kercheval) and Pamela (Victoria Principal), Rebecca became secretary to Herbert at his company, Wentworth Tool & Die.
