Howling:"Doctor who...?"

In Series 6 we find out that the Silence want to destroy the Doctor in order to prevent him going to the Fields of Trenzalore and answering the First Question, which is apparently "Doctor who...?" For some reason, they believe the answering of the question will lead to something terrible. But this doesn't really make a lot of sense, as the answer to "Doctor who...?" is simple: Doctor nothing; it's just "The Doctor." People have been assuming the answer is the Doctor's true name, but it's not. Why would this so terrify the Silence? 82.2.136.93talk to me 14:56, May 12, 2012 (UTC)
