My problem with Look Before You Sleep was, that it was OOC for twilight, because originally she wasn't even socially awkward. Fluttershy is socially awkward. Twilight is just anti-social.
This is probably a case of
Alternate Character Interpretation, but I've always seen pre-FIM Twilight as a study-obsessed bookworm, who ends up being
both anti-social and socially clueless. After all, if you don't socialize, how would you learn what the social norms
are? The fact that she uses reference books for even simple things like slumber parties and running a marathon indicate that (a) she
knows she's unaware of various social norms, and (b) she's still clueless enough to try to get the answers from a book, instead of
asking someone. Pity she didn't have a copy of "Winter Wrap-Up For Dummies" in the library.
As for fandom, I've always been a strictly Canon guy, myself. Fandom things are amusing, but in the end if it's not
Word Of God, it's just periphery fluff.
