For the longest time I've just sort of taken it at face value that Debbie made her do all that, I mean even if she was just trying to make Pixy normal, it wasn't an amazing thing to do. I know there's a Kiwi around here that knew/knows her IRL that has said it.
Honestly though, I'm starting to think that the whole blonde/tanning thing was something that she chose to do, but later on she made up some overblown story when she decided she was from grorious nippon. I mean it wouldn't be the first time she's lied about something and made someone else out to be horrible.
I don't know, maybe I'm just putting too much thought into a simple crazy weebaloo.
