Pam sees only pink tile, no Bobby anymore, camera pans down to see Mark Graison's body on the floor of the shower. Bobby, knowing that Pam has just married Mark, first visits Jenna, who, shocked, pulls him into her room and rapes him (off camera). Detectives reveal to the family that, with Miss Ellie's cooperation, Bobby was hidden away for months, his will executed, because the FBI and Interpol had become aware of an elaborate plot put in place by Katherine, just before she died, to anonymously hire assassins thru a shadowy eastern-european/oriental syndicate to kill Bobby -- and possibly other Ewings -- and so Miss Wentworth's death was unknown or irrelevant to the killers because they had no knowledge that she was their client.... thus explaining away retroactively the entire Angelica Nero storyline. When JR complains his private eye had verified all of it, the federal detectives show him a photo of his investigator, pin thru his neck, on the floor of a Fort Worth motel -- perhaps he'd stumbled across something Nero didn't want him to know... Jenna has that dullard look on her face when she and Bobby hear the TV report that Mark Graison is dead... Sue Ellen has a bandage and bruise, and Jamie was several yeards away from the car when it blew up... Donna is preggers again, much to her distress, as Ray finishes building his house.... Turns out the IRS worked with the other agencies so no fraud charges can be dumped on the Ewings for executing Bobby's will, and Harve Smithfield tries to convince JR not to waste time and money by suing his own mother or the feds, and that JR's time is better spent trying to buy back the parts of Ewing Oil he'd thought he'd purchased a short times earlier... Pam goes to her bedroom door at the end of the first episode of the new season to see Bobby's face; she hesitates, shakes her head gently, and then closes the door, leaving Bobby's face in partial darkness. Freeze frame.
First scene of second episode of the season: Bobby's comes into Pam's room and explains what happened, and Pam realizes she'd thought she'd seen him in the shower because she'd caught a glimpse of him across the street as she'd come out of her wedding to Mark, and due to the emotional shock of Mark's death... and then they're off into the new season.
Is it perfect? No. Ask me for details; watch me sputter.
