I remember an interview with Esther Shapiro (during one of her more lucid moments) in which she said that when she and her husband Richard were creating "Dynasty" they had already created Blake, Fallon and Steven when they realized they needed a sympathetic character to whom the viewers could relate. This is when they created Krystle. Peach Dynasty already has enough psychos: Claudia is a homicidal maniac, Kirby may be a pyromaniac and Melissa seems a little unhinged. Alexis is a gold digger and Fallon is a woman who would (figuratively) stab her father in the back to make a deal. We need a sympathetic, decent and honorable character we can root for. I hope Cristal Flores is an intelligent businesswoman who has been working to improve the lives of people living in "shithole" countries when she comes to the U.S. and learns that a recently deceased woman working at Carrington Atlantic had stolen her identity. Initially Cristal only intends to stay long enough to resolve issues resulting from the theft of her identity when she learns of the Clarke County toxic waste spill. Cristal decides to work on behalf of the residents of Clarke County when Blake decides to do some damage control; he tries to charm Cristal and offers her a job working for him where she can resolve the issue in a manner that is satisfactory to the victims of the spill as well as to Blake. Cristal is suspicious of Blake's motives but reluctantly accepts the job. Meanwhile, Alexis has been trying to take advantage of Celia's death to find her way back into Blake's life. Blake knows Alexis is trouble but he also finds her irresistible. Blake also finds himself being drawn toward this new woman who shares the name of his deceased wife.
