Oh man, all the treachery and politics coming out in this episode. It's a great blend of the fun of probending and the seriousness of the greater movement. I loved Amon's line of "cleanse them of their impurity." It furthers my previous notion of the Equalizers being a religious metaphor. This whole bit also ties nicely into the current (unfavorable) notion that the current religion of the world is science/technology. We're so obsessed with it and the commentary here is spectacular.
Beyond that, I loved the venture into backstory land with Tenzen and Bei Fong's past relationship. Also helped with characterization and uniting the fronts. And, and, and - who didn't love the cabbage seller from the original series? I was thrilled with the radio message regarding Cabbage Corp at the beginning of the episode - and how it connected with the world's technology. Brilliant!
