(From previous seasons reimagining of the 1983 TV miniseries, will be uploaded to.)
In the dark bowels of the mothership, Anna confronts her mother Diana—the previous leader of their race. So that she could seize power, Anna overthrew her mother and imprisoned her for the past 15 years, allowing the rest of their race to believe she was dead. Anna asks her mother about understanding human emotion and the human soul which she considers to be humanity's greatest defense as it empowers people. Diana discovers through Anna that Earth is the last viable planet close enough where the Visitors can continue their species, but tells her that using humans for breeding purposes will only ensure that the next generation of Vs have emotions and that she will be unable to control them. Meanwhile, Erica has Tyler's blood analyzed as she believes the Visitors may have done something to her when she was pregnant with him 18 years earlier. Ryan seeks advice from Father Jack regarding whether or not he has a soul, while Anna tries to lure him back to her side by giving his daughter an illness. Chad is a target of a Fifth Column attack. Erica and Agent Malik follow a lead where they both become suspicious of each other leading to a struggle which causes their vehicle to crash.
