Barry Corbin (Executor) previously played Sheriff Fenton Washburn in nine episodes of Dallas (1978) from 1979 to 1984.
This is the first time that Valene Ewing (portrayed by Joan Van Ark) has been seen onscreen since the reunion miniseries Knots Landing: Back to the Cul-de-Sac (1997), and the first time she has appeared in an episode of Dallas since the original series finale Conundrum (1991).
Though they hadn't communicated on screen since the fifth season of the original Dallas, thirty two years earlier, Gary Ewing and his daughter Lucy walk right by each other, without as much as a Hello.
Though they each spent close to fifteen seasons marrying, divorcing, remarrying and having many variations of relationships with brothers JR and Gary Ewing, respectively, this was the only time Sue Ellen and Valene ever had an onscreen one on one exchange.
