It's very hard for LKH to admit that Anita is not the only mixed person in the universe, but she tries. The way she treats mixed characters is...weird.
Yeah, I've noticed this, hence how I had her be all confused over Sati. I think there's also been the implication that Anita is a 'better' mixed person because she DOESN'T identify with the culture of her Mexican side.

Well...she's going to need magical energy...the problem is that the people available to donate are...yeah, not white enough. Just prepare yourself.
I know. Oh god I got there and I was nearly screaming.
