I have to confess, even though I think the Daleks have been overused and I'd been spoiled rotten for the finale, I got chills here.  I really did.  At this moment, approaching a battered and confused world, the Dalek fleet is as overwhelmingly terrifying as it ought to be.

Sarah Jane, the only companion to have been there at the creation of the Daleks, starts to shake.  Jack's and Martha's jaws drop. 

"What is it? Who are they? Do you know them, Jack?" Gwen asks, starting to panic from the reactions around her.  Jack's answer is to provide fanservice to Torchwood shippers of all stripes, throwing his arms around Ianto and Gwen and kissing them each in turn.

"There's nothing I can do," he says.  "I'm sorry... we're dead."

Sarah Jane is equally uncharacteristically useless.  In a move that's rightfully parodied in the latest issue of Doctor Who Magazine, she launches herself at Luke, crying so hard that she can barely get her lines out.

Rose swallows hard, straps her BFG back on, and strides out into the night.  Dalek ships are flying just over the buildings now, and if they'd used the atmospheric shield to keep the human race alive, it was only because they wanted practice shooting at running targets.  Rose strides through the streets as buildings explode behind her.

On the flagship, Nick Briggs is having fun talking to himself as the Daleks report that the battle stations are ready and "the Crucible is at 90%." One of the Daleks gloats that "the human harvest is about to begin."

In New York, General Sanchez is also shouting for battle stations. "Geneva declaring Ultimate Code Red.  Ladies and gentlemen, we are at war."  Explosions rock the UNIT base and Martha, running to the window, must be getting a huge case of post-traumatic stress syndrome as Dalek ships skim the skies raining death just as the Toclafane had done a year ago.

Back on the Dalek ship, the scarlet Supreme Dalek gloats that the Daleks are the masters of Earth.  Around him, hundreds of Daleks take up the chant.  "Da-leks-are-the-ma-sters-of-Earth!"

In the meantime, the TARDIS is flying shakily through space as the Doctor explains to Donna that the Shadow Proclamation are "a posh word for police. Outer space police."  Although we're shown a quick clip of the TARDIS spinning towards a space station in real time, rather than coming to a landing it materializes in a... well, the background makes it look suspiciously like a bathroom.

The platoon of waiting Judoon cock their weapons as the Doctor and Donna slide out of the TARDIS, holding their hands up.  David Tennant gets to show off his verbal skills as he barks out a long, rapid speech in Judoon that makes the squad stand down and take him to their leader, who is a lot less impressed.  The albino woman in black refuses to believe that the Time Lords are more than "myths and legends," telling the Doctor that he cannot possibly exist. 

"More to the point, I've got a missing planet," is his response.

If possible, she gets even more underwhelmed.  "You are not as wise as the stories say.  The picture is far bigger than you imagine; the whole universe is in outrage, Doctor."  Twenty-four planets are gone without a trace, lost in the same moment.

"Which ones? Show me!" the Doctor demands, running over the top of a stool on his way to her monitor.  You just can't take that Time Lord anywhere nice.  The display gets in a nice list of shout-outs to previous episodes - Woman Wept, Klom, even arguably a shoutout to old school and the fandom again, as Callufrax (spelled Calufrax on the fic-recommending community on LiveJournal) goes by.

"What about Pyrovillia?" Donna asks, remembering her adventures in Pompeii.

The Shadow Leader sneers "Who is the female?"

Donna is the last companion anyone can get away with dissing in the Whoniverse.  Donna promptly sneers right back that she's Donna, a human being and "every bit as important as Time Lords, thank you" as the Doctor smiles proudly.

The Judoon claims that Pyrovillia is a cold case; having disappeared more than 2,000 years ago, it cannot be related.  Neither can the disappearance of the Adipose breeding world, which Donna brings up next.

But the Doctor seizes the clue.  "That's brilliant!  Planets are being taken out of time as well as space!"

He busily starts creating a holographic list of the missing planets, adding in the two that Donna mentioned.  But it's not enough until he namechecks "Midnight" and adds in the lost moon of Poosh as well.

As the new little ball joins the rest of the holograph, suddenly the planets rearrange themselves.  It turns out that those particular astral bodies "all fit together like pieces of an engine."

"But who could design such a thing?" the Shadow leader demands.

"Someone tried to move the Earth a long time ago," the Doctor says softly.  "But it can't be."

Back on Earth, things are rapidly approaching a crisis.  The Valiant is down, falling from the sky.  Gwen and Ianto rattle off a list of bases invaded or destroyed while Jack tries to get Martha to run for her life.  She refuses.

General Sanchez has other plans anyway.  Project Indigo is about to be activated, and Martha is going to be the guinea pig.  Martha protests that it hasn't been tested while Daleks sweep through the UNIT base above them, wiping out the soldiers.  Behind a wall of wheel locks is a futuristic backpack/parapchute.

Jack, still connected via Martha's earpiece, begs her not to use it; it isn't safe.  An unimpressed Sanchez, who must have excellent hearing, snaps that Martha takes her orders from UNIT, not from Torchwood.  Martha is the only hope of finding the Doctor.  Moreover, he is entrusting her with the Osterhagen key in case all hope is gone.

"I can't take that," a horrified Martha whispers.

"You know what to do! For the sake of the human race!"

Daleks have breached the corridor.  Martha takes the key and pulls the ripcords on Project Indigo, the last sounds she hears being Sanchez's death yell and Jack shrieking "Don't do it!"

Jack kicks his desk in fury and grief, explaining to the rest of his team that Project Indigo is teleport technology stolen from the Sontarans, but without stabilizers or coordinates, Martha has been scattered into atoms.  "Martha's down," he announces.  Ianto puts a shocked hand over his mouth.
