The Dalek comes back to life so there's more running, at some point during which Rory points out that, between the fez and the mop, the Doctor now looks exactly like he did the first time he created this time loop and gave him the sonic, so the Doctor hops back to give Rory the sonic so he can free the Doctor to come give him the sonic... (Is it because of the collapsing universe that this is okay? They're all just playing in the starless margins anyway, so it's like scribbling on the back of a fax: Nobody would know anyway because it doesn't count. You could write horrible curse words, or the exact opposite of what it says on the front of the fax, and nobody would ever know. Is that it? That sort of makes me like this story more, if it's true.)
Cleverness, jumping about, Amelia wondering if the Doctor is just straight up magic or what, and then they set off running up the stairs, and then the Doctor remembers to hop back and tell Rory to put it in Amy's jacket, where it now is. (Some of these serve no purpose but cleverness, which makes them not so clever.) So then the Doctor hops all about, slipping the brochure through Aunt Sharon's door and dropping off the soda -- still cold, ha -- and telling them about the vortex manipulator and how it's awesome, and just when you're still clapping your hands and going more more the Doctor himself appears in front of the Doctor and, um, dies.
He hugs himself from the floor, prone, and whispers something specific to himself, and then dies. The Doctor seems not so worried though -- "I've got twelve minutes, that's good... You can do loads in twelve minutes. Suck a mint, buy a sledge, have a fast bath!" -- and then flourishes himself back up the stairs, calling after Rory and Amy... But not Amelia, who has been Cracked. So what about Amy? All three of them, now, are anomalies apparently, "hanging on at the eye of the storm," which is just thrilling! Nothing exists, so nothing they do matters, so they're free to save the universe. It's like if the words on the back of the fax somehow got to the person anyway, and changed everything. That is very awesome. While Amy grits her teeth and gets very angry about the thought of the Doctor dying (specifically, note, that "He'll find a way"), Rory very sweetly and reverently covers the dead Doctor up.
