Mack asks Gary if he wants him to try and track down Lucy in Europe so that they can tell her about Valene's death. This is the only episode of Knots Landing (1979) to reference any Dallas (1978) character by name after Pam awoke to find Bobby in her shower in the final scene of Blast from the Past (1986). The following episode, the Season Ten premiere Return to Camelot: Part 1 (1986), revealed that Bobby's death and the entirety of the ninth season were nothing more than Pam's dream. After the dream season revelation, there were no further crossovers between Dallas (1978) and Knots Landing (1979) with the exception of Gary and Valene's appearance in the former's series finale Conundrum (1991), in which J.R. was shown what would have happened to the Ewings and others if he had never been born.
