History
Aftermath
Having survived the incident, Davros recorded a "whole and true study" of Dalek history and science to ensure their purity and survival in case he ever died. In this study, he wrote that he was still connected to the life force of every Dalek, but that he had the stolen regeneration energy, making him question what may be possible in the future. He concluded his discussion by once again stating that his children were the ultimate form of life and that all other lifeforms needed to be exterminated. (PROSE: Secrets of the Dalek Laboratory)
