Celebrities from North America discussed most episodes of Doctor Who, from The Eleventh Hour to A Good Man Goes to War, laying special emphasis on what those episodes told audiences about the monsters encountered by the Eleventh Doctor (the Silence, the Silurians, Prisoner Zero, the New Daleks, etc.).
        Since this episode was broadcast prior to Let's Kill Hitler, it maintained the deliberate misdirection in The Impossible Astronaut that the Silence was a species.
