That's actually pretty interesting to know. =)
Though, I'm glad they didn't kill her off. She at not be a character many people like. But I like her, because she wasn't made to be as strong as Naruto & Sasuke. And I believe that's okay.
I got to see her develop/grow in other ways over the years and I'm grateful they kept her around. She knew she'd never be as strong as the both of them, but that didn't stop her from trying to improve herself. I admire that in her character.
