The word "Conspiracy" would suit this episode, perhaps the whole series, quite fittingly. That's actually very nice, because if build skillfully, they are indeed valuable plot elements.

And very good animation, like masamuneehs said. But I still don't know why all those people were just standing still when other people around them were tossed around like toys. I would have run like hell to take cover somewhere, not just idle and wonder when's my turn to fly head first and smash some windows. That scene could have used a little more animation, really.
