I wonder how they'll address the fact that the Doctor's apparently been wandering on his own for 200 years, since it was only
very lightly hinted at during "Closing Time" I believe that the clips of his shenanigans during the beginning of Series 6 are supposed to be what he was doing on his own, as well as cover what exactly he's been doing to attempt to restore his reputation as a Madman with a Box, rather than a great warrior.
Also - best theory I've heard so far: The eyepatches have an image of the Silence on them, and thus the people with them- Madame Kovarian & TONS of other people in the upcoming episode can see them without ever forgetting about them (since she sees the Silence in the background behind River and isn't at all startled by them).
If that's at all
CLOSE to what they are, suddenly the clip of River with an eyepatch is a lot less frightening in a bad way, and badass in a good way.
