text: Season 9 cliffhanger: Evil businesswoman Angelica Nero (Barbara Carrera) intends to kill J.R. and his cousin Jack (Dack Rambo) for double crossing her, but J.R. has her apprehended by the police. Unfortunately, Angelica has already had a bomb attached to Jack's car, which explodes with Jamie (Jenilee Harrison) inside. After hearing this on the phone, J.R. runs out of his office to go to Jack's apartment. As he leaves the office, Sue Ellen arrives in the other elevator looking for him. As soon as she enters J.R.'s office, another bomb left by Angelica goes off, and the entire floor that houses Ewing Oil explodes, showering debris onto the street below. The scene then shifts to Pam in bed, the day after her marriage to Mark Graison (John Beck). Pam wakes up to hear the shower running. Assuming it is Mark, she opens the shower door, only to find Bobby Ewing, alive and well. (In the Season Ten premiere, Bobby's death and all of Season Nine was revealed as a dream of Pam's).
  Season 10 cliffhanger: The Ewings suffer a devastating loss as Ewing Oil is closed down by the US Justice Department as punishment for J.R.'s shady dealings which caused an international incident. Pam, on her way home to Bobby from the doctor's office after finding out she can finally conceive a baby, crashes into a fuel tanker, which then explodes.
