Impressive that they managed to stay on board, the only things that weren't addressed were why Kyo-chan always disappears, what the deal was with EroYuu and to a lesser extent what the Twilight actually was. It was great how they reapplied the theme of being true to oneself when it came to Asuka, her flaw was "narcissism" and she got over it when she recognized she wasn't at the center of the world and she could finally forgive herself. Then her becoming an Equalizer at the end confirmed she stopped trying to be "someone else's" Asuka - a stand-in for Kyo mainly - and follow her own heart, thus becoming "whole" and "realizing a complete idea" as Seriosuka said.
As for the Twilight, it seems clear now that it is not a natural force of destruction, working to unravel creation to let it be born anew, but something more akin to sin in the christian tradition - or to evil in the platonic sense -, where it cannot act without a willing agent carrying it given the fact that it had to be "invited" by Lolisuka and that it needed Asuka for whatever reason.
Also, nice that Seriosuka "returned", as well as everyone else who got swallowed up like Kitta-sensei, who by the way finally married his girlfriend. It was all Lolisuka's delusion calling it a force of destruction, because then she is absolved of all guilt since she's merely carrying out what is already decided, but both its goals and modus operandi show quite clearly that the Twilight is mere stagnation, a bog of dead possibilities unlike the existence of the various Fragments which represent living possibilities and futures and were what allowed our Asuka to overcome herself. The very existence of Equalizers goes against the Twilight as a necessary counterpart, since they are the only ones capable of standing up to it and defeating Clutters. Why would there be beings that use the power of Truth and Resolve to fight the Twilight, if the Twilight itself isn't either a mistake, or simply an agent of decay, rather than death?
