The Bionic Woman
To maintain the show's plausibility, creator/executive producer Kenneth Johnson set very specific limits on Jaime Sommers's abilities. He elaborated, "When you’re dealing with the area of fantasy, if you say, ‘Well, they’re bionic so they can do whatever they want,’ then it gets out of hand, so you’ve got to have really, really tight rules. [Steve and Jaime] can jump up two stories but not three. They can jump down three stories but not four. Jaime can’t turn over a truck but she can turn over a car." These limits were occasionally incorporated into episodes, such as "Kill Oscar Part 1," in which Jaime is forced to make a jump that's too far down for her bionic legs, causing massive damage to them and nearly causing her death as a result.
The Return of the Six Million Dollar Man and the Bionic Woman
Former lovers, both bionically enhanced, Steve Austin and Jaime Sommers have been retired from the OSI for ten years. They have remained out of contact with each other due to the complex history of their relationship. In exposition, its explained that after the two fell in love, Sommers was in a skydiving accident which caused extensive injuries. She was rebuilt with bionics, but her body rejected them ("The Bionic Woman: Part 1 & Part 2"). The experience caused partial amnesia which made her forget her romantic feelings for Steve ("The Return of the Bionic Woman: Part 1 & Part 2"). She later fell in love with fellow OSI agent Chris Williams (as shown in season 3 of "The Bionic Woman"). Steve, not wanting to interfere, refused to go on a mission to aid Chris and Jaime. On that mission, the two became separated and an explosion hit Jaime, which caused a major concussion. She had to be evacuated, which left Chris alone and he was later killed by a sniper. When she recovered from the concussion, all of her memories were restored and her feelings for Steve came into conflict with her love and grief for Chris.
