SUPER EXHILARATING. I'm super pumped now!
Surprisingly Complex: M.S.S.S Episode 14
Now it's on! Okay, it was confirmed that the Serpent doesn't come from her doubt, but more likely her guilt. But that ending left me... Unsatisfied, addicted. But that's a good cliffhanger for you. Anyway, this episode has one of the best uses of character lens for a while, if not ever.
Remember the opening scene with Tsukihi? That was one hell of a character lens scene there. If I were to count the word "cute" in there, it would be damn too much. See how much it just started to pour after it was said the first time? Tsukihi either did not say the word so much, or Nadeko stopped listening anything else than that word. It's also a good way to tie the whole episode together. By the end of the scene with Tsukihi Sengoku starts to get really really anguished from Tsukihi, seeing her as a monster and a crime detective. It's the power of the lens.
By the way, when they were talking about Araragi's girlfriend, the name was left out on purpose. Nadeko thought that the girlfriend was Hanekawa, where as Tsukihi knew it was Senjougahara, but didn't realize Nadeko's mistake.
Anyway. After the glorious opening we get more Tsukihi and the cutting of the bangs. She couldn't hide behind her hair no more, causing some interesting things. When she can't hide anymore, she goes to the offensive, and it was really weird. It's a completely different Nadeko, but! Even though Nadeko said it was 100% her, I say it wasn't. I say that the aggression actually comes from the Serpent, and it was intentional. It was to put her into submission. Because if she doesn't have control over her body, it implies that she is doing something wrong, feeding her guilt, and thus feeding the Serpent.
Notice how the cutting of the bangs, which was at most, like, two centimeters, made a HUGE impact on her. That is change, she fears it. She fears it so bad, that she is hung up on loving Araragi, just so she can keep things status quo.
And the end of the episode, the infiltration of Base Araragi and finding the old-Hanekawa-esque porn mags made extra-clear that Nadeko had mistaken. Also tells us something about Araragi, too. He probably got those mags because Hanekawa changed appearance. Makes sense to me.
Now, to the ending which left me exhilarated. Nadeko wants her unobtainable love to be obtainable, but she really pleas for it only because she is being manipulated. The fact that the Serpent has a mission to complete for her gives it a perfect reason to take over her body, causing the flustercluck that was the arc's beginning.
TL;DR (Come on, this is one of the shorter ones):
Nadeko went a little nutty before her grumpy moment, and is being manipulated.
I never went in depth with the opening's lyrics, and I tell you they're important, there hasn't been a single opening without meaningful lyrics.
The lyrics themselves are actually pretty creepy. It's all about putting the world into submission if Araragi won't love her back. And by the fact that she wants nothing but everything, it just means everything she wants, meaning Araragi, obviously.
By the "delusions" she is singing about in the beginning, it's either the whole love toward Araragi, or she knows she's being tricked by the Serpent. If she knows she's being tricked, she just tries not to cause problems, causing her to believe her own delusions, leading up to her final demise. There's also an interesting part in the middle. "I understood nothing, but closed my eyes, and looking so very cute asked the stars for help." It signifies the importance of her bangs. They were her cover, so that she could close her eyes in peace and feign ignorance and helplessness.
The "If you will not fall in love with me too, nothing will ever change" is about her desire to keep the status quo, but with a bitter remark. Which is complimented by the ending of the song, where the whole world will be turned upside down just to get Him. It means she wants things to change, but is too afraid of it that she cannot.
