This is my story -
The four time travellers arive at a haunted house after Rory is told of a legend by a wise woman. In the house they're gonna find young Amy walking the corridors being chased by the darkness. As Amy and River go after the earlier younger self, the Doctor reminisces with Rory when they see two recognised symbols on the wall. As the Doctor thinks more and more of the timelords, and Rory thinks of his own childhood, they find themselves becoming part of the darkness. River and Amy however are encircled by the darkness, and I haven't worked out how they will survive.
