Steven Moffat has explained that events come to a head in the cliff-hanger for The Pandorica Opens.
“It’s not just the cliffhanger for Episode 12,” he said, “it’s like the cliffhanger for every single episode up until that point. This is where the wheels come off. Everything the Doctor is running from lands on his head today.”
Moffat also reckoned that his seven year-old self would be â€œcrying my eyes out by the end of 12. And then again at the end of 13 – but a different kind of crying”.
The Radio Times have printed a synopsis of the episode:
â€œA message on the oldest cliff-face in the universe, a puzzle box opening from the inside and a love that lasts thousands of years… The fates are drawing close around the Tardis â€“ is this the day the Doctor falls?â€
The synopsis also comes with this juicy and slightly spoilery piece by Moffat himself:
â€œThere was a Goblin. Or a trickster, or a warrior. A nameless, terrible thing, soaked in the blood of a billion galaxies. The most feared being in all the cosmos. Nothing could stop it, or hold it, or reason with it – one day it would just drop out of sky and tear down your world.â€
