1. Prior to taking over as showrunner and lead writer of "Doctor Who", how many episodes had Moffat contributed in the Russell T Davies era (2005 - January 2010)?
From Quiz "Doctor Who" - The Steven Moffat Years
Answer:
Six
Aside from Davies, Moffat was the only other writer to have contributed at least one episode to each of the first four series of the revived "Doctor Who". For Series 1, Moffat wrote the two-parter story consisting of "The Empty Child" and "The Doctor Dances", set in a Blitz-threatened London where a gas mask-wearing child roamed the streets. "The Girl in the Fireplace" was Moffat's Series 2 offering, with the French aristocrat Madame du Pompadour having her life interwoven with the Doctor's. In Series 3, Moffat's "Blink" was a standout and regarded as his best work yet, with the exceptionally frightening Weeping Angels making their first appearance. His fifth and sixth offerings formed another two-part story in Series 4, namely "Silence in the Library" and "Forest of the Dead", in which the Doctor met River Song, one of the most important women in his life, for the first time.
