Jack's bullets run out, and he tosses it aside and produces another, smaller gun from ...somewhere...and shoots with that, but no dice. The Daleks back him up against the wall, and he opens his arms to them. Delicto. Jack falls.
The Doctor finally finishes up the thing he was making, and as the Daleks crowd the room, he tells them that they need to think hard: "If I activate the signal, every living creature dies." God, on the screen, assures the Doctor that He is immortal. The Doctor Excellently Asks, "Wanna put that to the test?" But God knows the Doctor's buttons pretty well: "I want to see you become like me. Hail the Doctor, the Great Exterminator!" They play chicken, with the Doctor's hands on the plunger, about to activate it, angry but hesitating. God is all, "Prove yourself, Doctor. What are you? Coward? Or killer?" It's too much. Too many memories. Even if it's just one Dalek and a fucked up coterie, it still means he didn't do the unthinkable thing. These aren't Daleks, but they're close enough. What a weird inversion these two escapee Daleks put on the "everybody lives" thing -- they didn't die, so he's just shy of a genocide; two symbols of his just-incomplete damnation. Who are simultaneously the symbols of his doom. Which: Gollum, already. The Doctor's brain hurts for a while, and he lets it go, back to the lateral jump, and answers: "Coward. Any day."
God warns the Doctor that mankind "will be harvested," because of his "weakness," and the Doctor is like, "Bored of that." But I mean, yeah. At least the Doctor learned that he wasn't God; if nothing else, MI-5 Margaret and the Fourth Continually Shitty beat that out of him. Who knows how long he'll retain it, though. The Doctor: "And what about me? Am I becoming one of your angels?" I said the Doctor's nightmare was being caged up, alone, but also that he was bound to keep his spark, his individuality, which is what the Dalek kill. And these new Evangelical ones even more, maybe. Way worse than the Big Brother house, in terms of a hell. "You are the heathen. You will be exterminated." And the Doctor sighs, his Will and his Knowledge already gone. Operating on one-third of a soul. Full of painful, retained Memory. "Maybe it's time." And he closes his eyes.
Vworp! Yeah! The Daleks all alert each other to the shit they can plainly see, which is the TARDIS arriving, and the Doctor's eyes snap open in shock. "You will not escape!" shouts God, but like, I'm past caring about what God says at this point. The Doctor is totally going to escape, dude. Basically.
