A Good Man Goes to War Prequel Released

Hello. The Almost People left us with a giant cliffhanger (of which an analysis will be posted) for next week's episode - where is Amy? Who is Madam Kovarian? And will the Doctor and Rory find Amy? We will all find out next Saturday at 6:45pm. In the meantime, the new Prequel for the mid-series finale. It involves Dorium, the blue-skinned alien from the Pandorica Opens giving the brain of a Judoon to some hooded figures (members of Demons Run?) who want to imprison a little child... could it be the Doctor's? Maybe, but it could as easily be Amy's. To watch the Prequel, click here.
The synopsis of A Good Man Goes to War may hold some clues, so here it is:

Amy Pond has been kidnapped and the Doctor is raising an army to rescue her as the drama continues. But as he and Rory race across galaxies, calling in long-held debts and solemnly given promises, his enemies are laying a carefully concealed trap.

In her cell in Stormcage, River Song sadly acknowledges that the time has come at last – today will mark the Battle of Demons Run and the Doctor’s darkest hour. Both sides will make their sacrifices and River Song must finally reveal her most closely guarded secret to the Doctor.

I can't see anything there, but maybe you can. Finally, the Fourth Dimension has no new clues. Nothing. What has happened? We will find out in time.
