Upstairs on the roof, it's morning, which is funny, is it not, since there are no stars, and mornings imply suns, which are another words for stars. (Also, downstairs that goddamn Dalek is still running around and talking all chopped and screwed.) The sun is less like a sun and more like a TARDIS exploding at the end of the universe, keeping everybody warm. Even in her death.
Rory snottily explains that he can also, thanks to being made of plastic, detect a voice in the familiar VWORP VWORP sound of the sun, and the Doctor cranks it for Amy: "I'm sorry, my love. I'm sorry, my love. I'm sorry, my love." River, caught in the center of the explosion: The TARDIS's emergency protocols have sealed off the control room, putting her into a time loop at the heart of the explosion. We jump to the sun, where the TARDIS doors finally open again and again and again, on nothing, and every time she dies, and every time she apologizes to her beloved Doctor...
Until the time that he's standing at the doors, still closed, as she rushes toward them. "Hi honey, I'm home."
It's debonair and sexy and sort of magnificently cocky, this: Like he's finally speaking River's language back to herself. They bounce back down to the Museum rooftop, where there's a quick blue joke about Robot Rory ("I dated a Nestene duplicate once. Swappable head. It did keep things fresh") and another quick joke about his fez, which he has decided like bowties before them are "cool." Bizarrely, he looks incredible in a fez. Maybe he can just do things like this. Amy, chuckling and cute, snatches it off his head just in time for River to take aim and squareness it into oblivion. Normally this sort of thing would get on my nerves (Women: Can't live with 'em, can't save the universe they destroyed without 'em, bitches'll shoot your hat, when they're not telling you to shut up) but there's a relaxedness in all four of them, the actors themselves maybe, that makes it feel like, I don't know. Like we've all been invited to this wonderful, silly party.
Dalek. Again. For the fourth time in ten minutes. Although given the fact that the universe has ended, who else are they going to fight? Just the museum-grade Dalek that got woken up by the Pandorica. So there's shooting and running and four and a half minutes until it kills the Doctor, which he has, of course, on excellent authority. Meantime, here's a good question: Why is that Dalek here at all, to be woken up by the light-slash-"restoration field" of the Pandorica, when Daleks never existed and the whole universe is slightly larger than earth's starless sky?
