Ok, got it, I've just checked her last real fight and you're right (damn, I missed).
Even so, how's what she says a contradiction, KLG?
To me it looks more like that the shoot that normalized her for a while made Medaka acknowledge her abnormality, because she felt heavy and mindless and not in her everyday fitness. You can say it wasn't build up, but there are sudden developments that don't need a build up, right?
Well, not like it matters anymore now she has lost her memories. Smart move, Nishio.
