And so, watching this time, I knew it was definitely the final shot. In a few moments’ time. Douglas would call ‘cut’, and Matt, Karen and Arthur would step back out of the box for a laugh and a cry, I’d make some highly inappropriate jokes in place of a speech, and a few hours later, we’d all be at a party, and I’d be dancing very badly. But that’s just real life. What about the story?
What about the Ponds? Amy and Rory wouldn’t be coming back out of the box. Where do the characters go when the story is over?
I don’t know, of course - but wherever they go, I watched them leave. Douglas called ‘action’, our three heroes made their very last dash for the TARDIS and then Amelia Pond and Rory Williams stepped into the blue box and out of this world.
And I never saw them again.
