According to "legend," now, the Pandorica was historically and always accompanied by a nameless Centurion, which nobody I guess found odd. "He appears as an iconic image in the artwork of many cultures, and there are several documented accounts of his appearances and his warnings to the many who attempted to open the box before its time." He yanked the Pandorica out of the Blitz with his own two hands, because robot boys are quite strong. Amy's upset by the video presentation's presumption that Rory must've died in the Blitz, because nobody ever heard about him again. (That is sad. God, I hope Rory's okay!) This story touches Amy on a very deep level, because -- if you are the lady involved -- that is a very awesome thing for a boy to do, regardless of its pointlessness.
So I guess I get it. Or maybe I'm just willing to buy anything and everything Karen G tries to sell us, because I adore her and I would love reasons to like Amy. But first, a bunch of running around, this time because of the stone Daleks in the museum suddenly jumping to life for some reason -- Amelia is like, "This is awesome!" -- and then the Doctor appears again, grabbing his Fez of Future Past and whisking both Ponds around and being generally dashing and sexy. Some sort of danger happens, and then Rory -- now a security guard with a cute haircut -- opens fire on the robot with his robot hands, resulting in the favorite Dalek thing: "Vision impaired!"
Rory tries to apologize for killing the now very happy Amy all those years ago, but she just (of course) tells him to shut up and snogs him until the Doctor gets uncomfortable. Amelia -- thirsty from having her soda stolen earlier that day and then a long afternoon of hiding in dusty museum exhibits and then being chased around by a psychopathic garbage can -- asks for a drink, and the Doctor's like "It's all mouths today, isn't it?" which creeped me out somehow, and then they discuss how the light from the Pandorica falling across that Dalek is what woke it up.
Which I thought was the implication, but I still don't get it. I guess if it's all miracles and wizards and fairytales and the light from the Crack and the light from the Pandorica and blithely not to say cockily jumping into pretty serious/obvious paradoxes and plotholes and whatever, it doesn't benefit anybody to wonder about this stuff. (And here I'd been given to understand that the whole point of watching this show was to worry about just this stuff and discuss it endlessly on the internet and get really mad and say mean things and construct elaborate proofs about made-up stuff. Figures the one time I actually have concerns about magical story logic, they are invalid. Other hand, the way the Doctor says "Pandorica" makes my knees melt, so let's stick with the good.)
