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 Sue Ellen (Linda Gray) had married into the 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.
