Kyle is first seen as a child in the episode "Happy Landings," where it is revealed that he was another boy trained at the Centre under the care of Mr. Raines (who then was still Dr. Raines). Kyle's story is then expanded further in the two-part "Back to the Dragon House." According to "Back to the Dragon House," Kyle is the brother of Jarod, though neither remembered this fact to the memory repression following the trauma of their kidnappings. Like Jarod, young Kyle is to be a Pretender, though Dr. Raines also wishes to mold the boy into a killer operative with no morality.
