Shortly before her marriage to Clayton, Miss Ellie was kidnapped by Clayton's mentally unstable sister Jessica, who conspired with J.R. to stop the wedding. Clayton and Miss Ellie honeymooned in Greece, and returned to Southfork, in spite of Clayton's reservations about living in Jock's home and his constant "shadow". To ease his transition, Miss Ellie redecorated Jock and Miss Ellie's bedroom, but Clayton went on business trips to avoid staying at Southfork. Finally, Miss Ellie had J.R. and Bobby (Patrick Duffy) move Jock's portrait from the living room at Southfork to Ewing Oil. Clayton became very good friends with his stepson Bobby and Ray, but remained a self-imposed enemy of eldest stepson J.R., getting into many arguments and fights with him. Clayton has a brief infatuation with a young British model named Laurel Ellis (Annabel Schofield), mirroring Jock's near-affair with his former secretary Julie Grey (Tina Louise), after feeling neglected by Miss Ellie. He also suffered from amnesia and nearly left Miss Ellie until recovering. Clayton sold his refinery businesses to Ewing Oil and at one point began a cutting horse breeding enterprise with Ray.
