Storylines
The character of Kristin first appeared on Dallas during the second season in the company of her mother, Patricia Shepard (Martha Scott). Patricia was always proud that her daughter, former beauty pageant winner Sue Ellen (Linda Gray), had married into the prominent Ewing family. Patricia was hoping her younger daughter Kristin (then portrayed by Colleen Camp) would also find a successful man to marry. Kristin spent some time at Southfork Ranch and J.R. (Larry Hagman) came up with a plan for Kristin to seduce Bobby. (Bobby had just recently separated from his new bride Pam, and J.R. was plotting to break them up for good.); J.R.'s plan backfired. Bobby wasn't interested in Kristin romantically and nothing happened. Bobby and Pam reconciled. Kristin left town for a while.
Kristin returned to Dallas at the beginning of the third season (now portrayed by Mary Crosby). J.R. offered Kristin a job working for him at Ewing Oil and a condo for her to live in. Eventually, J.R. and Kristin began a long term affair. Kristin helped J.R. by finding out valuable information from J.R.'s business partners. J.R. failed to come through on the promises he made to Kristin that she would be rewarded for the spying she had done, being that he would marry her. Kristin became bitter with J.R., feeling he had betrayed her. J.R. had also managed to anger many of his business partners and family members. J.R. was shot by an unknown assailant at the end of Dallas'''s third season.
