I remember taking an English or Literature class when I was young, and analyzing "Hamlet" in depth. We discussed the motivations of Hamlet and the other characters. Why did he wait until the end of the play to confront his uncle? Why didn't he do something about it immediately, instead of agonizing over it for the whole play? As the discussion stretched longer and longer, I eventually came to the conclusion that the reason Hamlet did what he did was because it made for a more interesting story, and not because Hamlet was a "real" person with complex subconscious motivations. He waited because that's how he was written by Shakespeare, and if he hadn't, the play would have been over in 20 minutes. Simple as that.
I get a similar feeling when I see in-depth discussions about reality shows. Don't get me wrong, I enjoy "Heroes Of Cosplay." It ain't Shakepeare, but I find it entertaining. Those of you who enjoy it, I'm glad you are so emotionally invested in the stories and characters you see. And sometimes dissecting a show is part of being a fan.
Sometimes questions don't have answers. Sometimes the only answer to "Why did she say that," or "why isn't she nicer" or "why didn't she credit him" is simply "because that's what happened in the episode," or "because otherwise nothing would have happened, and that might not be very interesting."
Of course, sometimes there are answers. For example:
No word on why the Lulu dress that appeared at Katsucon 2012 wasn't ready for Emerald City.
The short answer is, the Lulu we made for Katsucon last year was a piece of crap held together by glue and wishes, that barely survived long enough for the skit she did. We were trying to actually make it well, for the first episode. When it looked like we weren't going to get the outfit done in time, we might have fallen back on the Katsucon outfit it still existed, but that thing had been discarded long ago (though we saved a few elements that were worth keeping, like the jewelry and accessories).
BTW, despite the rumors, Yaya does actually make her own costumes. I've seen it myself when I've been over to their house. At most, Brian (her bf) will do a coat of spray paint or some minor touch-ups. But he's mostly way too busy making the products they sell at the 2 - 3 dozen conventions they go to each year. They make all that stuff in-house, so he barely even has any time to work on his own projects (he's building a Keaton batmobile), let alone work on her costumes.
