Five different stories, by five different writers. I was under the impression that they're possibly interrelated only in that they describe Twilight's plans starting to come into play, although nobody knows it yet.
There are several important points to make concerning this issue...spoilers if you haven't read it yet.
1. As said above, new Slayers are continuing to be activated. Which means, new Potentials are being created. Which means that Twilight isn't going to be able to stop the Slayers just by killing them all, or even killing all the Potentials. The only way to stop the Slayers is to put an end to the magic that creates them. (The First Evil was apparently unaware of this as well.)
2. The whole world is apparently perfectly aware of the existence of vampires. When did that happen?
3. The new Slayer's story (she doesn't get a name) is handled strangely. Her story begins from her POV, with what's going through her mind told in the form of "voice-over" captions. But this ends when she walks into Harmony's party, and everything from then on is told only through action and dialog... right up until the Slayer is stabbed and bitten and (maybe) killed. This is a bit like losing the cell phone connection to this girl's thoughts just before the most important events. Shouldn't we have continued to hear what was going through her mind?
4. Did Harmony actually kill the Slayer on camera? She stabbed her in the shoulder... probably not fatal, and then bit her neck. But Harmony has been biting people non-fatally all through the episode. Is MTV really willing to show someone being killed on camera as part of a reality show? Does the FCC have no problem with this? What about MTV's insurance company? Or the police? I know this is just a story, but this whole thing just doesn't come across as plausible.
5. The Slayer had a cross around her neck which should have made it very difficult for Harmony to bite her there. The cross was there when the Slayer kicks Harmony off the balcony... but missing seconds later when she jumps on top of Harmony and is stabbed and bitten. Where did it go?
6. The Slayers have managed to operate in secrecy for a long time now, but suddenly some twit at MTV "does some investigating" and finds out all about them. I'm guessing that's because MTV is infiltrated by the Twilight organization, who arranged Harmony's show to rally public opinion against the Slayers, and that's where they got their info on the Slayers. What about Anderson Cooper, who "did some digging" and found that the Slayers "say they're our protectors"... huh? Who's been giving official Slayer statements to CNN?
7. Since when has being bitten on the neck been something pleasurable that normal people would seek out? I can see it as a kinky thing or a form of self-harm (like Riley did), but... doesn't it hurt? A lot? WTF?
Very strange storytelling going on here.
