Synopsis

There have been many ways to invade the Earth, and the Doctor has seen them all – or so he always thought. And then the human race wakes up one morning and discovers the world has been overrun by… small black cubes. Which then proceed to… do nothing at all. A plan is afoot, humanity is endangered – but by what and how and, above all, when?

For the first time in his world-saving career the Doctor has to call upon one of the least of his virtues: patience. And the Ponds face something possibly more terrifying than any world-ending apocalypse: the Doctor is moving in!

Continuity

• Rory's father Brian reappears. (TV: Dinosaurs on a Spaceship)
• The Eleventh Doctor, Amy and Rory have fish custard. (TV: The Eleventh Hour)
• Kate Stewart is the daughter of Brigadier Alistair Gordon Lethbridge-Stewart. She previously appeared on-screen in HOMEVID: Downtime. She shortened her family name when she joined UNIT as she wanted to be judged on her own merits.
• It is ten years since the events of The Eleventh Hour.
• The Doctor, talking to a flying cube, says "Is that all you can do? Hover? I'd a metal dog that could do that" referring to K9 Mark IV (and possibly to K-9 Mark II from K9 (TV series)).
