The Doctor's great-aunt

The Doctor had a great-aunt who lived in a draughty house high in the Gallifreyan mountains and would sing him lullabies. The Eighth Doctor described her as "terrible". (AUDIO: Together in Eclectic Dreams)

Behind the scenes

• The Doctor's having had a great-aunt was first confirmed in the 2010 video game The Mazes of Time, where he mentions his great-aunt Inertia; the audio Together in Eclectic Dreams was released twelve years later. Whether Inertia is the same great-aunt who sang the Doctor lullabies has not been made clear.
