The Scarlet Dalek is calling for the surviving humans to be brought to the Crucible when a new voice calls from the dark.  "Supreme Dalek, is there news?"

"Is there news of him?"

"No reports of Time Lord.  We are beyond the Doctor's reach."

All we see of the new speaker is a sharp-nailed fetish glove, taping at a console.  While the Supreme Dalek blows off the idea of the Doctor foiling their plans - the Supreme Dalek is obviously unaware of 45 years of show history - the hand announces that "Dalek Caan is uneasy."

A metallic finger flips a switch and a light flashes onto one of two creepiest sights this season - an opened casing, the Dalek inside twitching its tentacles at the sudden brightness.

Supreme Dalek still isn't impressed.  "The abomination is insane." it points out.  The new voice rebuts that it still only speaks the truth, and furthermore, it had made everything possible.

(For those who've mercifully forgotten the Daleks Do Manhattan two-part episode from last year, Caan was the surviving Dalek of that encounter, having thrown himself into the temporal void to escape the Doctor.)

He's much the worse for wear now, wriggling his naked tentacles and flopping around a bit.  According to the intervews, Nick Briggs was having the time of his life getting to do more than e-nun-ci-ate-threats-care-fulllly into the ring modulator, for Caan sing-songs, babbles, and warns them all that "the threefold man... the Doctor" is coming before breaking into classic insane evil giggles.

Back on the Shadow Proclamation space base, the Doctor and the leader are bent over the monitor, trying to figure out what to do.  Donna is sitting on the stairs, still stunned, and listening to an odd, overlapping heartbeat.  Another albino woman with freaky red contacts, slightly younger than the leader, offers her water.  She also offers the insight that there was something on Donna's back and condolences for her loss.

"Yeah, my whole planet's gone," Donna sighs.

"I mean the loss that is yet to come" is the unreassuring response.

The Doctor has been oblivious to all of this, but he does come over to badger Donna to tell him what might have been happening on Earth as a warning.  Electrical storms?  Freak patterns?

"There were the bees disappearing," she says defeatedly.

"The bees disappearing," he repeats sarcastically.  Then he repeats it again, first in wonder, then excitement, finally launching himself with a yell back at the monitor.  Both Donna and the Shadow Leader think he's nuts, but in a burst of exposition he explains that the bees were probably going home without even so much as a last message of "so long and thanks for all the pollen."  They would have traveled by tandoka, which leaves a trail, and look at that, whatever stole Earth used the same technique!

"We can follow the trail!" he exults.

"Stop talking and do it!" Donna yells back, leading the full-on charge to the TARDIS.  

There's still a trace, a faint and scattered one, but enough to follow.  The Doctor sticks his head out just long enough to tell the Shadow Leader what can be done - only to be rocked by the news that she is accordingly impounding himself and the TARDIS.  "We are declaring war across the universe, and you will lead us into battle!"

It's a beautiful acting moment for Tennant as the Doctor relives the last, horrible moments of the Time War.  Surprisingly, he doesn't lecture or bluster about war not being the way, or how unfit he would be to lead. He just swallows hard and says that he'll give her the door key.

Then, naturally, he slams the door in her face and runs like a rabbit while the Shadow Leader orders for him to stop, screaming over the sound of the TARDIS dematerializing.

On Earth, the Daleks are starting to round up people.  One family resists, returning to their home, which the Daleks explode with them inside.

Wilf and Sylvia are watching around a corner, Wilf armed with a paintball gun.  At the sight of the burning building they run, only to be caught by another Dalek.  Wilf paint-balls it in the eyestalk, but that's not as effective as he would have hoped; the Dalek just sears the paint off.  But while it works itself up into a frenzy of "Exterminate! Exterminate!" it is exterminated itself from behind, a huge blast blowing its entire top off.

Wilf looks through the burning casing at Rose, who is recharging her BFG with another pump.  "Wanna swap?" he asks, offering the paint gun.  (Wilf, don't ever change!)

Rose establishes that they're Donna's family and that they can't contact her.  Wilf is trying to establish Donna's galactic coordinates while Sylvia still insists that his stories of Donna traveling in time and space are ridiculous.  Wilf finds it equally ridiculous that Sylvia can continue to deny it while Daleks glide through the streets.

Rose is crushed.  "You were my last hope.  If you can't find Donna, we can't find the Doctor. Where is he?"

He's in the TARDIS, which has taken him to the Medusa Cascade and stopped.  "I came here when I was a kid," he muses, "just 90 years old.  It was the center of a rift in time and space." It's also the end of the trail, which has gone cold, and nary a sight of the missing planets.

Donna panics. "You never give up!  Please!"  

But the Doctor stands silent and unmoving.
