Miss Ellie mentioned Bobby going to California too, as seen in the Knots Landing pilot. Lucy mentioned visiting her parents to Alan Beam and Muriel in Second Thoughts. On Dallas, JR referenced meeting Karen Fairgate. Gary mentioned Sid and Karen Fairgate to Miss Ellie. On Knots Landing, JR mentioned Lucy’s wedding, which aired on Dallas the following night. In Five Dollars A Barrel, JR asked Gary if he was still working at that used car lot (Knots Landing Motors). Miss Ellie acknowledged Gary’s strength that wasn’t there before (from his life on Knots Landing), when he came for Bobby’s funeral. In Love and Marriage, Jock said that Gary was doing fine in California, just days before Knots Landing began. Bobby referenced Miss Ellie’s mastectomy to Valene on Knots Landing. Karen Fairgate mentioned Jock’s recent death to her brother. And JR on Dallas put Kristin on a plane to California and she showed up in Knots Landing.
Was Gary and Val's divorce even referenced on Dallas? I can't remember it, but it's some years since I last watched either show.
On Dallas, Lucy mentioned that Gary and Valene had split up, in reply to a question from Don Lockwood and with Sue Ellen present.
To my knowledge, Gary’s jailing in the murder of Ciji, Val’s breakdown and vanishing after her twins “died,” Gary’s “death,” etc., was never mentioned on Dallas. Am I wrong?
You’re not wrong. Although on Knots Landing, Abby had a one-way telephone discussion with Miss Ellie when Gary was in prison.
