A boy on a bicycle appears randomly, and is turned to dust. The Doctor gets very intense with them about leaving town, but they are not really buying what he's selling. Rory, slightly elsewhere, slows down for Amy's sake and starts whinging about how he fixed all these old people and kept them alive. One old lady gets all in their faces and Rory tells fat pregnant "Chubs" to get out of the way so he can kill the old lady. To his credit, it takes him a bit of moaning and a sharp word from Amy before he can bust a log over her old lady head.
Locked into a nice little house, Amy is about equally upset about how they've abandoned the Doctor and how Rory called her "Chubs." Rory comforts her, to the best of his ability, so you know they're going to do something stupid if they don't wake up soon.
Meanwhile, the zombies have a very wobbly Doctor pinned in a butchers -- the Doctor actually checks to make sure the sign says CLOSED -- and the DL accuses the Doctor of being a vegetarian, "You big flop-haired wuss," and I must say that if the DL is all about supplying the Doctor with autocritique he seems to be saying that the Doctor is gay a whole lot. I mean, for now, because later on he'll just go an extended diatribe about how the Doctor is a pedo, so let's not give DL all the credit we might.
The birds finally come, and the DL points out that if the Doctor falls asleep right now, "Several dozen angry pensioners will destroy [him] with their horrible eye things," which is accurate and funny and immediately negated by a terrible pun, and the Doctor pops his fingers in his ears long enough to get inside the freezer before he passes out.
On the cold dead TARDIS, the Doctor says they have to agree which is the real world. The Doctor finally brings up Rory's and maybe his additional factors, which include the idea that maybe they're voting for their regular lives with Amy because they're actually competing over Amy. Amy is grossed out, obviously, but frankly all of them should be. As freezer burn sets in, they talk about their various frozen body parts and put on ridiculous ponchos that she has cut out of blankets.
