text: Pilot Season/Season 1 cliffhanger: Although this really was not a cliffhanger, the end of the fifth episode of the original Dallas miniseries saw J.R. (Larry Hagman) go up to the loft of the barn to talk to Pam (Victoria Principal), who had gone up there to find her cousin Jimmy (James Canning), after Digger (David Wayne) had fallen off the wagon at the Ewing barbecue. J.R., intoxicated, tries to convince her to tell Bobby (Patrick Duffy) not to leave the ranch. However, she does not want to be bothered, and, in trying to escape J.R., she falls from the loft, landing square on her stomach. Pam, who is pregnant, miscarries her unborn child. Later, Sue Ellen (Linda Gray) questions J.R. as to whether it was really an accident or did he mean for Pam to fall on purpose. J.R. says, "I did not." When Sue Ellen asks J.R. if he cares that Pam lost the baby, J.R. does not answer her, leaving it up to the viewer to decide.
  Season 2 cliffhanger: Sue Ellen's drinking problem has landed her in a sanitarium, where she is pregnant with a child she believes is Cliff's (Ken Kercheval). She escapes from the sanitarium, gets drunk, and then gets into a severe car accident, putting her life and the baby's life in danger. The doctors deliver the baby, named John Ross Ewing III, but he is very small on delivery and is not out of the woods yet; nor is Sue Ellen, who, as the episode ends, is clinging to life. A distraught J.R. is watching his wife at the end of the episode in tears, saying that she has "just gotta live".
