John Forsythe is again crossing over from Dynasty, with Diahann Carroll.
This is the first time that Joseph Campanella shares a scene with someone other than Barbara Stanwyck - in this case, Tracy Scoggins.
John Forsythe makes a guest appearance as Blake Carrington. His character experiences some shakes in a scene with Jeff and feels unwell in a scene with Jason. This ties in with what was happening concurrently in Dynasty (1981) Season 6 where Blake was being systematically poisoned by the Krystle lookalike impostor, Rita, in her efforts to stop him sleeping with her.
