Love how they handled the 'center' discussion and reveal. A cynical and frustrating girl, indeed.
The deadpan delivery of the prestigious girl was a welcome surprise, and I'm glad it won't be the last we see of her. It's too bad Kana doesn't see the forest for the trees when it comes to Aqua, but I suppose part of being in love is letting your emotions cloud your rational judgement to a degree.
Why do you think that? Is it because of the timing? She may not have conceived until after leaving the place, but she still could have met someone there, I think.
