One Moment

One Moment was the 5th episode of the Bluesilver sixth series. It could be counted as the first part of the series finale, but is considered by most to be a separate story.

Synopsis
"It's like finding a laptop in Ancient Egypt. That room looked brand new because it is; time is shrinking like a sponge losing water... Ignore that comparison, actually, it was rubbish." - The Doctor

In an ancient castle in the far future, the TARDIS becomes the core of a machine that threatens to compress time into a single moment. To save the universe, The Doctor, Amy and Rory have to combat the vicious Griever and appeal to the soul of a damaged woman mourning the loss of someone she can no longer remember.
