Everything beginning with Pam Ewing waking up to see Bobby in the shower, including the two reunion movies, is just a dream.There is no plausible way that Pam could have dreamed a full season of episodes in eight to nine hours of sleep. Also, she would have to have known that there was a mysterious woman stalking Bobby before the "dream season" began, and we saw no hint of that at the time. But it is acceptable for everything seen by viewers since the end of the "dream season" to be the dream of a comatose person who has been unconscious since 1986. Perhaps someone shot J.R. and was successful. This is supported by the fact that the dream revelation was ignored by the spinoff series Knots Landing.
J.R. Ewing wasn't really suicidal at the end of the series.I don't buy J.R. as somebody who can be told what to do. Especially not by some figment of his imagination. But he was freaked out by his hallucination, and in the end took up violence against it by shooting the mirror instead of himself.
John Ross is not J.R.'s biological child but Elena Ramos is.Elena has been around Southfork her entire life and she'd certainly be the right age to be the result of one of J.R.'s affairs. She clever and good at finding oil, Sue Ellen has taken a shine to her and it would make a very satisfying end to the Bobby/J.R. feud if their children (who are not biologically related to each other) end up together. Obviously neither Elena nor J.R. are aware of this at this point. As for John Ross (who could be Cliff's son afterall) it would be equally satisfying to see his talk about being a real Ewing to Christopher blow up in his face.
The creators' long-term goal is to Pass the Torch to the younger generation (Christopher, John Ross, Elena, etc.).Hence Bobby's intestinal cancer and J.R.'s (allegedly) weakened health.
A number of characters in Revolution watched this show before the blackout occurred.If Jeremy Baker is familiar with One Life To Live, then it's not a stretch that a number of the older characters in the cast are familiar with this show.
