"The Cylons are such a frightening concept - not knowing who is real. No way"

The quote by Mary McDonnell talks to the worry and uncertainty that the Cylons give the world. The Cylons are a race of robotic beings that look and imitate human beings, making it hard to tell who is genuine and who is not. This produces a sense of fear and fear, as one never understands who is a Cylon and who is not. McDonnell's quote reveals the worry and unpredictability that the Cylons bring, and the concept that there is no chance to know who is genuine and who is not. This fear of the unidentified is an effective idea, and McDonnell's quote speaks with the power of the Cylons and the fear they bring.
