Plot summary
Cal and Sarah hide the car and the assumed-dead Daniel. Sarah leaves Kira with Cal and returns to Mrs. S's home with Felix, where they find news clippings of Susan and Ethan Duncan, the founders of Leda and the cloning project and Rachel's adoptive parents. Mrs. S, meanwhile, reunites with Carlton Redding, who helped smuggle her and Sarah out of London. Helena escapes from the ranch after Henrik's daughter Gracie tries to kill her and remembers that Henrik took something from her. Alison wakes up in rehab. She is told by Donnie that she will not see her children unless she stays a week. Sarah sneaks into Rachel's apartment, only to be captured by the very much alive Daniel. As he tortures her, Helena arrives and kills Daniel. At the ranch it is revealed that Henrik took Helena's egg cells for in vitro fertilization.
