Are you my mummy?

Behind the line

What it means

Our interpretation.

A child's plain question becomes the most frightening thing the revived series had done. It is the longing of a wartime orphan, said in a flat, toneless voice through a gas mask, and the story's resolution is that the answer was always yes. The Doctor himself later repeated it as a gag in The Poison Sky, and it still turns up on Halloween costumes, since it is the line that sent a generation behind the sofa.

The question is the calling card of the Empty Child in "The Empty Child", the Ninth Doctor and Rose story by Steven Moffat that BBC One broadcast on 21 May 2005 (part one of two, with "The Doctor Dances"). It is set in London during the Blitz in January 1941. The boy, Jamie, was killed in an air raid, then revived by medical nanogenes from a crashed ship, which left a gas mask fused to his face. He wanders the bombed streets asking everyone he meets this one question, and anyone he touches begins to change into a gas-mask zombie too. The nanogenes finally recognise his real mother, Nancy, in the second part, and heal him.
