At the end of the fourth season, Kristin returned yet again claiming to have given birth to her and J.R.'s son and wanting money. She is soon thereafter found drowned in the Southfork Ranch swimming pool. She had overdosed on drugs and, in her stupor, fell and hit her head and went over the balcony railing, landing in the pool. After Kristin's death, her son Christopher is adopted by Bobby and Pam Ewing. It was later revealed by Bobby that Kristin actually miscarried J.R.'s baby. Kristin then married petty criminal Jeff Farraday (who was the same blood type as J.R.) and gave birth to Christopher. She later returned to Dallas leading J.R. to believe Christopher was his son and trying to blackmail him, ultimately leading to her death.
