Through the character of Dalek Sec, the episode suggests that even the most "perfect" killing machines are susceptible to the transformative power of human emotion. While the Cult of Skaro’s experiment ends in failure and death, it leaves a lasting question: is it truly survival if you lose the capacity to feel?.
