Simon comes to terms with what his ancestors did to the world and realises that although he can not change the past, he can do something positive with his own life by helping his people collaborate with the mutants. He comes to believe that the nuclear war was meant to happen, so that Laura (whom he finally acknowledges as his cousin) and the rest of her kind could be born. Catherine initially acknowledged Ophelia who she met during the cattle mission, but Simon denied any knowledge of her. However at this point he finally admits to Laura that he is in fact her son. Laura was angry at first for Simon lying to her and denying an old woman the pleasure of meeting another family member, but then comes to terms with the situation. She takes Simon on her horse back to the house where he will reveal all and use his knowledge to allow the new generation to expand their skills and make the new way of life a better place like it once was.
