Rose gets nearer the rooftop, as the child looks down at her, begging him not to move. A rope...swings into view from somewhere, and Rose just...takes hold of it, for some stupid reason. I can handle gas-mask zombies and "Moonlight Serenade," but this mysteriously appearing rope that Rose just grabs really hacks me off.
Meanwhile, the audience is still laughing, and the Doctor is still looking around at them all, like, "What's so funny?," which makes them laugh more, and he keeps going, and knowing it's the Blitz, as we will, you can see where they're coming from: "It's just, there's this thing I need to find, would've fallen from the sky a couple of days ago..." That's like classic comedy, if somewhat British. Then a siren goes off, and everybody starts to evacuate for the raid. "...With a very loud..." the Doctor says, and looks up at the ceiling, where the siren's coming through, and then at all the people rushing out of the building. At the back of the hall, there's a poster reading, "HITLER WILL SEND NO WARNING!" He trails off: "...Bang?" Alone, he makes a hilarious face that says, "Awww, man!"
Rose is now climbing the rope, expending all her energy on doing something amazingly stupid, on which I have the full agreement of the music. Even the child figures it out: "Balloon!" From which Rose is now hanging. For no reason. Well, perhaps it was cloudy, and she just generally thought a rope appearing out of nowhere was just the kind of luck she's used to. And maybe she doesn't let go immediately because she's a clutcher like her boyfriend. And maybe leaving the Doctor without a second thought so she could join a ghost story already in progress a few feet away -- and that the Doctor noticed it no more than she did -- was just plot shorthand, and they actually trust each other so much that they know they can just randomly meet up back at the TARDIS later, because God knows after the immense fuckup Rose perpetrated last week, she's earned that kind of trust. Maybe all those things are true. Or, all sarcasm aside, I'm willing to admit that there's a high probability that I'm missing something obvious. But still. Rope. Grab. Aloft. Screaming "Doctor! Doctor! Doctor!" And floating over the TARDIS, meaning that Rose didn't even get ten yards out before screwing up this week. And that's when she sees the German planes, dropping bombs on London, and rethinks her shirt. The planes zoom toward her, across a sky all indigos and oranges. The Jenny Sparks t-shirt didn't do it, but the sky sure does: that's an Authority sky.
