On Floor 500, the computer confirms a breach, and the Editor giggles kind of crazily: "I knew it...It's someone inside that room! Which one?" We focus on Rose and the Doctor and Adam, the last of whom is wigging out this time because he can see Cathica's very useful brain. (What was the worst part for Rose? I guess just the fun time all the aliens were having. That's way less stressful than this. No, well, Earth blowing up. I think maybe Rose wins after all. Plus Adam being a pussy and all.) Rose asks Adam whether he wants to get out of there, but Adam = Knowledge. "No...no! This...technology, it's amazing!" The Doctor almost snaps his fingers: "This technology's wrong." The music goes all "We're on the case," that discotheque-ish dance mix sound, and Rose looks up excitedly: "Trouble?" She and the Doctor grin wolfishly at each other, Adam completely left out: "Oh yeah."
Two stories here, before we continue. The first one's Zoroastrian, and the second one is Gnostic. Stick with me.
First, in the Avesta, Angra Mainyu, or Ahriman, is the Evil Spirit of the God Ahura Mazda -- specifically, the twin of Spenta Mainyu, whom Zoroaster used to illuminate the two principles of creation and destruction which combined in Ahura Mazda. (Compare with Shiva.) Ahriman chose evil, and, in doing so, created death. On Judgment Day, Ahriman will be destroyed and disappear from the world forever. But some believe that the whole material world is just a trap created by Ahura Mazda for Ahriman anyway, meaning that when he destroys the world, we will be free, as well. So that's one story: if you're trapped in God's prison with the Devil, and the Devil wants out, who's really the bad guy? Ask Milton.
