I just don't get why so many fans wanted or expected a heel face turn from Sonata Dusk. As for me, I never saw any hint of remorse or doubt about her actions as a member of the Dazzlings. Not once did she look even the slightest degree uncomfortable with what was going on.

Yeah, I get that she's ditzy and that she's cute, and that she loves tacos.

I even compared her to Avatar: The Last Airbender's Ty Lee, who <<don't click if you don't want spoilers>>

But really, I never saw any hint of redemption in Sonata herself throughout the entirety of the film. And it baffles me that anyone could look at the character and seriously see any hint of desire to turn from her evil ways. Oh, well. -_- I guess if you look cute and ditzy, you can get away with anything.

To make the point, I offer this:

After watching Twilight outright cry because of what Flash Sentry said to her and how he behaved, this appears directly afterwards, and Sonata is smirking the entire time (not to mention channeling Doctor Evil). Like, so a villain. And a moment later, she laughs just as loud and long as the other two do. Why no expectations of "coming to the Light side" for them?

To conclude... Sonata does not want to be redeemed. She does not deserve to be. She is a villain, end of story. A cute, somewhat distracted villain, but a baddy nonetheless.
