The Dalek turns on the basement screen again -- Goddard notices first, of course -- and prefaces that it's speaking only to the Doctor. "You're gonna get rusty," says the Doctor. "I fed off the DNA of Rose Tyler. Extrapolating the biomass of a time-traveler regenerated me." Dumb. I get that this show is about silly phlebotinum stuff like that, and I'm clearly willing to overlook it, but sometimes it seems like its own worst enemy. It almost makes a point -- Rose humanizes everyone around her, because she's that awesome -- but either explain the thing or don't. This explanation that doesn't even kind of make sense just confuses this issue. Plus, I don't even wanna think about what else traveling in the TARDIS has done to Rose. So the Doctor and the Dalek chat about how it's been looking all over for other Daleks, which it knows are gone, and the new problem there is that it's just, as the Doctor says, "a soldier without commands." The Dalek goes kind of nuts about how, in the absence of any real meaning, it'll go back to Directive One: "The Dalek instinct to destroy! To conquer!" Daleks are, like, 90\% the voice. It's so creepy and angry and robotic and nutty at the same time. And the Doctor finds that boring and stupid, and tries to explain that there's no Dalek empire to destroy for, but instead of replying that "Exterminate" is fun all by itself, the Dalek just asks him what it should do. The Doctor: "If you want orders, follow this one: kill yourself." But that's no good, because that's acting against the survival of the Daleks. So finally the Doctor just gets pissed: "The Daleks have failed. Why don't you finish the job and make the Daleks extinct?" There is Method spittle. "Rid the universe of your filth! Why don't you just die?" Which is very...oh, I see the Dalek agrees: "You would make a good Dalek." Again, thanks for cutting my entire steak for me. It makes me feel very grown up. The screen goes blank, and the Doctor okays them to seal the Vault. Van Statten happily does all the rerouting stuff, and the Doctor's irritated by this happiness, and Goddard points out that Rose is still behind the bulkheads.
