Continuing from my previous post:

That jump is another thing that hints at her superior abilities. I thought 'almost two meters' was a little abnormal for a high school women's high jump, and it turns out it is. Apparently the high jump record for Texas (thanks Google) is 1.93 meters. Saya just missed 2 meters. I had the same impression as Kai at first. I thought she was faking a little bit, even though that whole image really didn't fit the image we all got from the movie.

I'm guessing her abilities were stunted somehow, but they still were fairly superior. After the 'transfusion' she'll be even stronger.
