13. '"Are You My Mummy?'
From: "The Empty Child"/ "The Doctor Dances"
Premiere: May 21, 2005 / May 28, 2005
Faced with a genuinely terrifying epidemic during the height of the London Blitz, the Ninth Doctor and Rose encounter a mysterious boy with a gas mask fused to his faces, who blankly repeats a chilling question: "Are you my mummy?" Along with Captain Jack Harkness (John Barrowman), whose popularity would earn him the lead role in Doctor Who spin-off Torchwood, the Doctor resolves the calamity, and in a rare celebratory moment beams with joy: "Everybody lives!"
